That is, the dynamic torque that the power tool applies to the bolt, overcoming the friction. The axial preload force for the bolts generated by the dynamic torque meets the engineering requirements for the preload force. Generally, the torque value preset by the tool or equipment is the dynamic torque value.
The dynamic torque sensor provided by Sino-Inst is a resistance strain dynamic torque sensor. dynamic torque sensor Torque measurement using strain gauge technology.
A strain bridge is formed on the elastic axis. The electrical signal of the elastic shaft being twisted can be measured by supplying power to the strain bridge. After the strain signal is amplified, it undergoes pressure/frequency conversion. becomes a frequency signal proportional to the torsional strain.
What is the purpose of the force torque sensor?
The force torque sensor is divided into two categories: dynamic and dynamic. Force torque sensor is the detection of torque torque perception on various rotating or non-rotating mechanical parts. And convert the physical changes of torque into precise electrical signals.
The force torque sensor can be used in the manufacture of viscometers, electric (pneumatic, hydraulic) torque wrenches. It has the advantages of high precision, fast frequency response, good reliability and long life.

The torque transmitted by various rotating power equipment systems is extremely efficient.
It can detect the rotational speed and axial force while detecting the torque.
It can be used to manufacture viscometers, electric (pneumatic, hydraulic) torque wrenches.
Torque sensors are not common in our daily life, but their application is very important. The torque sensor on the car checks the torsional deformation of the torsion bar and converts it into an electrical signal. This electrical signal is transmitted to the electric power steering system under the battery.
The sensor consists of phase splitter units 1 and 2 and a torsion bar. Sensor 1 is located on the steering spindle and sensor 2 is located on the pinion shaft. After the torsion bar is rotated, the two phase splitter units create a relative angle.
The converted voltage signal is transmitted to the electric power steering system. The electric power steering system determines the corresponding working voltage of the EPS steering motor according to the relative resistance. The location of the two cells is also used above.
The electric power steering system only starts the motor to generate electricity when steering is required. This can reduce the fuel consumption of the engine.
It can provide power under various driving conditions. Reduce motor unevenness. The output torque of the motor is assisted by the action of the transmission. Assist system interference, improve the vehicle’s steering characteristics, and improve the vehicle’s active safety.
Without hydraulic circuit, it is easier to adjust and detect. Assembly automation is higher. Different models can be quickly matched by setting different programs. Shorten production and development cycles. No oil leakage problem, reduce environmental pollution.
Electric power steering systems primarily use torque sensors to detect the magnitude and direction of torque or the angle produced by the steering wheel when the driver steers. And convert the required information into digital signal input control unit. Then there is the axis control unit pair.
These signals are calculated to obtain a torque compatible with the driving conditions. And this command is used to drive the motor to work. The output torque of the electric motor is assisted by the action of the transmission.
It’s not hard to see that torque sensors are very important. Damage to the car’s torque sensor directly causes the car to lose its steering assist function during driving. Stiff steering failure.
Such torque sensors are very important in automotive safety issues. The quality of the torque sensor directly determines the safety factor of the car.

Some of his most notable projects include the development of an intelligent control system for oil refineries, the design of a cutting-edge distributed control system for petrochemical plants, and the optimization of control algorithms for natural gas pipelines.
The 1050C Dynamic Micro Torque Sensor is suitable for low to mid-range torque measurements. Measurable measuring 0.1/0.2/0.5/1/2/3/5/10 Nm. The maximum speed does not exceed 4000 rpm.
In the dynamic measurement process, the measuring element needs to lead the signal line from the rotating shaft to the control circuit of the fixed housing for signal processing.
If it is led out by the collector ring and the carbon brush (similar to the motor brush), it is a contact type; If the principle of electric, magnetic and optical sensing is adopted, the signal signal is directly transmitted instead of the collector ring and the carbon brush, that is, non-contact measurement.
According to material mechanics, when a torque is applied to a shaft, it will cause a torque deformation. It consists of two physical quantities, one is the torsion angle and the other is the maximum shear stress or strain.
As long as one of them is measured, the torque of the shafting can be obtained according to the relevant calculation formula. Therefore, according to this measurement principle, it can be divided into torsion angle measurement and strain measurement.
Principle of strain measurement.
The most traditional method of strain measurement is to paste resistance strain gauges. With the development of science and technology, in addition to resistance strain gauges, there are many new methods. Such as acoustic surface wave strain measurement, piezoelectric strain measurement and strain measurement by the stretching effect. But the essence of its measurement is to obtain the strain value.
Traditional resistance strain gage torque transducers have strain gages as bridges, glued at 45° and 135° on the elastic axis. When the elastic shaft is torqued, the torsional deformation will lead to the change of bridge resistance, and the change of the strain bridge resistance will be converted into the change of the voltage signal. The signals transmitted from the rotating shaft to the fixed housing mainly include carbon brush contact, electromagnetic induction and wireless transmission.
When the existing torque sensor is used, it is mostly used as a precision torque measurement. After a long time of use, it will cause mechanical fatigue. Therefore, it must be calibrated and tested.
Turn on the industrial control host and open the test software. Make sure that the connection between the pressure sensor and the motion card is stable. The numerical value is within the range of error (0.01gf.cm-0.03gf).
Assemble the auxiliary connectors.
Open the software to select the corresponding range of the sensor. Then open the calibration sensor interface. Clear the value when the sensor has no load.
Select a suitable weight according to the sensor range. Select a small weight for a sensor with a small range, and a larger weight for a large range. For example, choose 200g, 100g weight for 2N.m, choose 500g, 1kg weight for 50N.m. Tie the weight to one end of the connecting piece. Hang it on one end of the pulley through the rope along the groove of the standard piece. Keep the contact state without external force Stablize.
On the software calibration interface, click Allow Calibration. Enter the torque value of the calibration weight (gravity * force arm), and click OK.
Wind the weight in another direction. Check the reverse force value. If the difference is large (>0.5gf.cm), take the average value of the positive and negative force values.
The calibration cycle is normally 1 year. If it is repaired or adjusted during use, it needs to be re-calibrated.
Torque sensors are precision measuring instruments used to measure various torques, revolutions and mechanical thermal efficiencies.
Determine the distance between the prime mover and the load according to the connection form of the shaft and the length of the Dynamic Micro Torque Sensor. Adjust the distance between the prime mover and the load shaft so that the coaxiality of the shaft is less than φ0.03mm. Secure the prime mover and load to the reference plane.
Put the couplings on their respective shafts.
Adjust the distance between the torque sensor and the reference surface. The coaxiality of its axis with the prime mover and the load shaft is less than φ0.03mm. And fix the Dynamic Micro Torque Sensor on the reference surface.
Tighten the coupling and the installation is complete.

Torque is usually referred to as external torque. For example, the rotation of the main shaft of the lathe is an adverse effect of the benefit of the external torque supplied by the power unit. Whereas torque is internal torque. When the spindle bearing is working, the secondary benefit of the cutting speed of the CNC blade to the spindle of the machine tool causes it to cause rotational elastic deformation. It can be used to estimate the torque size.
Torque is the torque that produces a flipping effect or rotational deformation of an object, which is equivalent to the multiplication of the force and the moment arm.
Torque is a parameter that is very frequently involved in rotating dynamic systems. In order to detect the rotational torque, the rotation angle phase angle sensor is used more.
The relatively perfect detection technology of torque test is strain force measurement technology. It has the advantages of high precision, fast frequency response, good stability and long service life.
The special torsion resistance strain gauge is hung on the elastic shaft to be measured with strain force viscose, and a strain force bridge is formed. If the power supply is switched on and off during the supply work to the strain force bridge, the light bulb number that the elastic shaft is twisted can be detected. This is the most basic torque sensor approach.
Dynamic torque transducer: mainly used to measure torque and speed in rotating occasions. Dynamic torque transducers can be divided into large-range torque sensors, micro-range torque sensors, and disc torque sensors according to their shape and range.
The measurement principle of the torque transducer: using the strain gauge electrical measurement technology, a strain bridge is formed on the elastic shaft, and the electrical signal of the elastic shaft being twisted can be measured by supplying power to the strain bridge. After the strain signal is amplified, it is converted into a frequency signal proportional to the torsional strain after pressure/frequency conversion.
Commonly used dynamic torque sensors mainly have the following forms:
Inductive torque sensor: This type of sensor mainly adopts a non-contact measurement method. This kind of torque sensor has a long life, high reliability, and is not easy to be worn.
Potentiometer type torque sensor: This type of sensor can be divided into gear type, torsion bar type, and arm type according to the type. Among them, the torsion bar measurement has a simple structure and relatively high reliability. It was widely used in the early days. Sensors of this type are contacting and suffer from wear that reduces their performance.
Metal resistance strain gauge type: This type of torque sensor is mainly composed of a measuring bridge by pasting strain gauges on the elastic shaft. When the elastic shaft is subjected to torque, it will produce a small deformation and cause the bridge resistance to change. .And the change in the resistance of the strain bridge is converted into a change in the voltage signal to achieve the torque measurement we want.
Torque can be divided into dynamic torque and static torque, which have a great impact on the final assembly of the product. Therefore, in the actual processing process, it is very important to distinguish between the two. Today we are going to tell you the difference between dynamic torque and static torque.
Dynamic torque: It is the peak value displayed in real time during the assembly process when the fastener is tightened. That is, the dynamic torque that the power tool applies to the bolt, overcoming the friction. The axial preload force for the bolts generated by the dynamic torque meets the engineering requirements for the preload force. Generally, the torque value preset by the tool or equipment is the dynamic torque value.
Static torque: refers to the torque required to overcome static friction after a fastener has been fastened and we continue to rotate in the direction of tightening. Generally, the peak torque we measure with an analog hand wrench is the static torque.
Torque sensors are the detection of torsional torque sensing on various rotating or non-rotating mechanical components. Torque sensors convert physical changes in torque into precise electrical signals. Torque sensors can be used in the manufacture of torque wrenches.
Sino-Inst is a manufacturer of Dynamic Torque Transducers. We offer more than 10 types of Dynamic Torque Transducers. Dynamic Torque Transducers can measure a variety of different mechanical power, rotational speed and torque measuring devices.

High pressure rotameter is suitable for flow measurement of high pressure liquid and gas. Standard type rotameter: DN15-DN50, can withstand 4.0MPa. High pressure rotameter: DN15-DN50, can withstand 25MPa. The pressure level of the jacket is 1.6MPa, and the special type should be negotiated with our engineers before selecting and ordering. High temperature metal tube rotameter can be applied to temperature range: 100℃~450℃ The high-pressure rotameter adopts an advanced magnetic sensor that detects the change of the magnetic field angle without contact. And with a microprocessor system. It can realize liquid crystal indication, accumulation, and remote transmission (4-20Ma). Pulse output, upper and lower limit alarm output and other functions. This type of intelligent signal transmitter has high precision and reliability.
The high-pressure metal tube rotameter is the force that the upper and lower ends of the float generate differential pressure to form a rising force when the measured medium passes through the conical measuring tube from bottom to top.
When the lifting force on the float is greater than the weight of the float immersed in the fluid, the float will rise. The area of the annulus will increase accordingly. The fluid velocity at the annulus will drop immediately. The differential pressure at the upper and lower ends of the float will decrease. The float is stabilized at a certain height until the lift force is equal to the weight of the float immersed in the fluid.
The height of the float position corresponds to the flow rate of the measured medium.
The float has a built-in magnet. When the float moves up and down with the medium, the magnetic field changes with the movement of the float.
a. For the local type, the rotating magnet in the local indicator is coupled with the magnetic steel in the float to rotate. At the same time, the pointer is driven to indicate the flow rate at this time through the dial.

It is widely used in the measurement and automatic control of liquid and gas flow in national defense, chemical industry, petroleum, metallurgy, electric power, environmental protection, medicine and light industry and other departments.
What Is Difference Between Rotameter and Flow Meter?
A rotameter is a device that measures the flow rate of liquid or gas in a closed system. It consists of a float that moves up and down in a tube, based on the fluid’s flow rate. The faster the fluid flows, the higher the float rises.
A flowmeter is a device that measures the volume of liquid or gas that flows through it. There are many different types of flowmeters, each designed to measure different types of fluids. For example, positive displacement flowmeters measure the volume of fluid that passes through them, while rotameters measure the rate of flow.
Choosing the right flow meter can be difficult, because there are so many different types available on the market. How do you know which one is right for your specific application?
Sino-Inst offers a wide range of high pressure flow meters that are specifically designed to operate in demanding applications. Our high pressure flowmeters are made from stainless steel construction and are ideal when measuring the flow of fluids under high pressures.
Yes, rotameters are affected by changes in pressure. When the pressure decreases, the rotameter will read a lower flow rate. Similarly, when the pressure increases, the rotameter will read a higher flow rate. This is because the rotameter measures the fluid’s velocity, and changes in pressure will affect the fluid’s velocity. Therefore, it is important to keep the rotameter’s pressure at a constant level if you want to accurately measure the flow rate.
The flow detection element of the rotameter is composed of a vertical tapered tube that expands from bottom to top and a float group that moves up and down along the axis of the tapered tube. Below, I will give you a specific introduction to the classification of rotameters.
Glass rotameter:
Glass rotameters are mainly used in various departments such as the chemical industry, petroleum, light industry, medicine, fertilizer, chemical fiber, food, dyes, environmental protection, and scientific research. Used to measure the flow of single-phase non-pulsating (liquid or gas) fluids. The anti-corrosion glass rotor flowmeter is mainly used for the detection of corrosive liquid and gas medium flow. Such as strong acid, strong acid, oxidant, strong oxidizing acid, organic solvent, and other corrosive gas or liquid medium flow detection.
The main parts such as the liquid plastic tube rotameter cone tube are made of AS, ABS plastic. Has relatively good corrosion resistance. The product also has the characteristics of reasonable structure, small size, lightweight, and the tapered tube is not easily broken. The plastic tube rotor flowmeter can be widely used in chemical, environmental protection, food, and other industrial sectors.
Plexiglass rotameter:
Plexiglass rotameter is divided into panel type plexiglass rotameter and pipeline type plexiglass rotameter.
Plexiglass rotameter also has the characteristics of high transparency, intuitive reading, not easy to break, lightweight, long life, and convenient installation and connection. However, the tapered glass tube of plexiglass cannot be used for organic solvents (such as trichloroethylene, dichloroethane).
Metal tube rotameter:
Metal tube rotameter is divided into on-site pointer indication type and remote transmission type.
Metal float flowmeter is a kind of flow measuring instrument commonly used in industrial automation process control. It has the characteristics of small pressure loss, large detection range (range ratio 10:1), and convenient use. It can be used to measure the flow of liquid, gas, and steam. It is especially suitable for medium flow measurement with low flow velocity and small flow.
The metal float flowmeter has a local display type and an intelligent remote transmission type. With pointer display. Instantaneous flow, cumulative flow, liquid crystal display. Upper and lower limit alarm output. Cumulative pulse output, standard two-wire 4-20mA current output, and other forms. Provide users with a very wide choice of space. In addition, the instrument uses a high-quality MCU micro-processing system. Ensure the excellent performance of the flowmeter in various applications.

What is the difference between a resistance temperature detector (RTD) and a thermocouple? Both RTDs and thermocouples are sensors used to measure heat such as Fahrenheit and Kelvin. These devices are used in a wide range of applications and settings, often presenting people with the dilemma of choosing between RTDs or thermocouples. Each temperature sensor has its own advantages and disadvantages that make it suitable for certain conditions and environments.
RTDs are made of metal wires, usually copper or platinum, that offer resistance to the flow of electricity. The RTD’s resistance changes when its temperature changes, allowing it to be used as a gauge for measuring heat. RTDs are considered to be more accurate than thermocouples as they have a linear relationship between resistance and temperature. RTDs are also less affected by electromagnetic fields than thermocouples.
RTD Working Principle
The full English name of RTD is “Resistance Temperature Detector”, so to be precise, it should be translated as “Resistance Temperature Detector”.
RTD is a special kind of resistor whose resistance value increases as the temperature increases and decreases as the temperature decreases. In industry, this feature is used for temperature measurement, so RTD is also commonly known as “thermal resistance”.
Not all metals are suitable for making RTDs. Materials that meet this characteristic need to meet the following requirements:
The resistance value of the metal has a linear relationship with the temperature change energy;
The metal is more sensitive to temperature changes, that is, the resistance change (temperature coefficient) caused by unit temperature changes is relatively large;
The metal can resist fatigue caused by temperature changes and has good durability;
There are not many metals that meet this requirement. Common RTD materials are: platinum (Pt), nickel (Ni), and copper (Cu).
Take platinum thermal resistance as an example. According to the different resistance values, it can be divided into Pt50, Pt100, Pt200, Pt500 and Pt1000.
The numerical value in the name indicates the resistance value of the thermal resistance at 0°C.
For example: Pt100, indicating that the resistance value of the sensor at 0°C is 100Ω. And Pt1000, it means that the resistance value of the sensor at 0 ℃ is 1000Ω. The resistance value of RTD thermal resistance at different temperatures can be approximated by the formula: R=R0(1+αT).
in: 1) R0 represents the resistance value of RTD at 0℃; 2) a is called the temperature coefficient, which represents the change value of the resistance at unit temperature; 3) T represents the measurement temperature, the unit is °C;
According to the number of lead wires of RTD thermal resistance, RTD can be divided into two-wire, three-wire and four-wire.
The lead of the two-wire RTD is to directly lead out two wires at both ends of the resistor to the temperature measurement module. The temperature measurement module adopts the principle of bridge balance, and RTD is used as one arm of the bridge to measure.
A three-wire RTD can largely eliminate the influence of the sensor leads themselves on the measurement results. The detection accuracy is greatly improved compared to the two-wire system.
Resistance Temperature Detector advantages
No compensation line is required, and the price is cheap; It can transmit electrical signals over long distances; High sensitivity and strong stability; Good interchangeability and high precision.
Disadvantages of thermal resistance:
Although thermal resistance is widely used in industry. But it requires power excitation. Temperature changes cannot be measured instantaneously. The temperature measurement range is limited and the application is limited.
What is Thermocouple?
Thermocouples, on the other hand, are made of two different types of metals that are joined together at the sensor end. The junction between these two metals produces a voltage that is proportional to the temperature difference between the junction and the measuring point. Thermocouples are less expensive than RTDs and can measure a wider range of temperatures. They are also faster at responding to changes in temperature.
Thermocouple Working Principle
A thermocouple is a temperature sensing element. It converts the temperature signal into a thermoelectromotive force signal and converts it into the temperature of the measured medium through an electrical instrument.
The basic principle of thermocouple temperature measurement is that two homogeneous conductors of different compositions form a closed loop. When there is a temperature gradient at both ends, a current will flow through the loop. At this time, there is a seebeck electromotive force – thermal electromotive force between the two ends. This is called the Seebeck effect.
The two homogeneous conductors with different compositions are the hot electrodes, and the end with the higher temperature is the working end. The end with the lower temperature is the free end. The free end is usually at some constant temperature.
According to the functional relationship between thermoelectromotive force and temperature, a thermocouple indexing table is made. The index table is obtained under the condition that the free end temperature is at 0°C. Different thermocouples have different scales.
When a third metal material is inserted into the thermocouple loop. As long as the temperature of both junctions of the material is the same. The thermoelectric potential generated by the thermocouple will remain constant. That is, it is not affected by the access of the third metal into the loop.
Therefore, when measuring the temperature of the thermocouple, the measuring instrument can be connected. After measuring the thermoelectromotive force, the temperature of the measured medium can be known.
Thermocouple Advantages:
High measurement accuracy: The thermocouple is in direct contact with the measured object and is not affected by the intermediate medium.
Fast thermal response time: Thermocouples are sensitive to temperature changes.
Large measurement range: thermocouples can measure temperature continuously from -40 to +1600 °C.
Reliable performance and good mechanical strength.
Long service life and easy installation.
Types and structures of thermocouples
Types of thermocouples Thermocouples include k type (nickel-chromium-nickel-silicon), n-type (nickel-chromium-silicon-nickel-silicon-magnesium), e-type (nickel-chromium-copper-nickel), j-type (iron-copper-nickel) , t-type (copper-copper-nickel), s-type (platinum-rhodium 10-platinum), r-type (platinum-rhodium 13-platinum), b-type (platinum-rhodium 30-platinum-rhodium 6) and so on.
Structural form of thermocouple: The basic structure of a thermocouple is a thermal electrode, an insulating material and a protective tube. Display instrument, recording instrument or computer and other supporting use. In field use, thermocouples suitable for various environments are developed according to various factors such as the environment and the measured medium.
RTD stands for Resistance Temperature Detector, but is also known as PRT (Platinum Resistance Thermometer).
A platinum resistance thermometer (PRT) is an RTD that uses platinum as the sensing element. The most common PRTs are Pt100, Pt500 and Pt1000. (PRT is just a more specific name for RTD)
The first step in identifying an RTD is to find out how many lines it has (2, 3 or 4). Then you can connect the RTD to the multimeter. If it’s a pt100, it should read between 107-110Ω at room temperature. But if it’s a pt1000. You should get a reading of 1007 – 1100Ω. This confirms it’s a Pt1000.
PLEASE NOTE: These readings are standard for new RTD sensors. If the sensor is damaged or used continuously. The readings may vary.
The international standard IEC 60751:2008 defines the resistance versus temperature characteristics of RTDs. Within this standard, in order to provide good interchangeability, there are standards of accuracy. Class A and Class B are two accuracy standards. We provide a tolerance reference table.
We get asked this question a lot, but Pt100s and Pt1000s are two types of RTDs (Pt500s are another type of RTD, but now obsolete).
RTDs use cables because they detect temperature by calculating resistance changes in the material. So you can simply order RTDs with long leads or buy additional cables to expand on your own.
When choosing an RTD, the following factors must be considered:
What temperature are you measuring (surface or immersion in solid, liquid or gas)?
If a fast response time is a must, see the RTD Technology page for various factors in selecting a response time.
Fits the specific dimensions required for your application, such as probe diameter, probe length, compression fittings, required connector types, etc.
Do you need special sheath materials?
Do you need to calibrate the sensor?
Does the sensor need to be resistant to chemicals/abrasion/vibration or any other environmental factors?
Is there high electromotive force (electromagnetic interference) in power switching, rectification or radio waves?
Any other installation considerations? (eg sensor needs to be bent to form before installation)
Distance between sensing area and instrument
Sensing ambient temperature over sensor length
Connection Preferences
Current wiring configurations such as 4-wire sensors will not be compatible with 3-wire configurations.
As a rule of thumb, RTDs should be immersed 4 times the length of the element. (Flat-film elements are typically 2-3mm, while wire-wound elements are about 15mm or more).
We are often asked this question, but Pt100 thermocouples do not exist. A thermocouple is a type of sensor, and a Pt100 is a type of RTD, another type of sensor.
A Pt200 sensor is an RTD, Pt200s have a resistance of 200 ohms (Ω) at 0ºC. The Pt200 sensor is now obsolete and has been replaced by the Pt100 and Pt1000 sensors. The Pt500 sensor is also an outdated RTD.
A Pt500 sensor is an RTD, Pt500s have a resistance of 500 ohms (Ω) at 0ºC. The Pt500 sensor is now obsolete and has been replaced by the Pt100 and Pt1000 sensors. The Pt200 sensor is also an outdated RTD.
Conclusions, which one should you use?
It really depends on the specific application and what is more important: accuracy or speed. If you need to measure very high or very low temperatures, a thermocouple is the better choice. If you need more accuracy, then an RTD is the way to go.

Mechanical diesel flow meter is a volumetric meter for continuous or intermittent measurement and control of diesel or other liquid flow in pipelines. It has many advantages such as large measuring range, high accuracy, small pressure loss, strong viscosity adaptability, ability to measure high temperature and high viscosity liquid (diesel), convenient calibration, and installation suggestions. It is suitable for flow measurement in petroleum, chemical, chemical fiber, transportation, commerce, food, medicine and health departments.
Sino-Inst mechanical diesel flow meter solutions come together here and allow you to select from various flow rates or technologies. When it comes to technologies, the turbine or oval gear type diesel flow meters can all be purchased directly from our website. We have a variety of mechanical diesel flow meters suitable for most fuels, including diesel, bio-diesel, kerosene, gasoline, oil, DEF, heating oil, grease and certain chemicals. mechanical Diesel fuel meters are available in several sizes from 1/2″ up to 8 “.
Diesel is a kind of light petroleum, which belongs to the fuel of diesel engine. The use of high-speed diesel engines on cars is more fuel-efficient than gasoline engines.
Diesel demand is growing faster than gasoline. Diesel engines have higher thermal efficiency and higher power than gasoline engines. The fuel consumption per unit is low and relatively economical, so the application is increasing day by day. In many occasions, it needs to be measured.
For oil tanker or diesel storage tank pipeline transportation, it is more suitable to choose a flowmeter with higher measurement accuracy. Because it is not only convenient for trade settlement, but also high precision. The measurement is accurate and can be used for a long time.
According to the role of diesel: the use can be divided into marine diesel engine, locomotive diesel engine, automobile diesel engine, power generation diesel engine, agricultural diesel engine, construction machinery diesel engine, etc.
Diesel Fuel: Diesel fuel is primarily diesel. Light diesel oil is usually used for high-speed diesel engines. Light diesel or heavy diesel for medium and low speed diesel engines.
Oval gear flow meters are our most commonly used Mechanical Diesel Flow Meters.
The oval gear flowmeter is composed of a metering box and a pair of elliptical gears installed in the metering box, and the upper and lower cover plates form a sealed crescent-shaped cavity (due to the rotation of the gear, it is not sealed) as the calculation unit of a displacement .
The flow meter is mainly composed of a housing, a counter, an elliptical gear, and a coupling (magnetic coupling and axial coupling), etc. As shown in the figure.
1.Counter 2. Transmitter
3. Accuracy adjuster (used above DN50)
4. Sealed coupling
5. Front cover 6. Cover plate
7. Oval gear 8. Shell
9. Rear cover
When the measured liquid enters the flowmeter through the pipeline, the pressure difference generated at the inlet and outlet pushes a pair of gears to continuously rotate, and the liquid measured by the crescent-shaped cavity is continuously transported to the outlet. The product of four times the secondary displacement is the total amount of the measured liquid flow.
The elliptical gear generates a torque to make it rotate under the action of the pressure difference △p of the measured medium.
The rotor 1 and the rotor 2 are alternately driven by one to rotate the other. There are two magnets on each rotor as signal generating elements. There is a magnetic signal detecting element at the center of the two axes at the bottom of the cavity. Whenever the magnet turns to the detecting element, the sensor counts as a pulse.
Each pulse corresponds to a certain amount of medium discharge F, F=XXml/p, so the volume flow Qm per unit time can be obtained: Qm=F*H, F is the amount of medium removed by each pulse; H pulse per unit time number.
Advantages of Oval Gear Mechanical Diesel Flow Meters
High measurement accuracy: 0.2 and 0.5;
The mechanism is simple, firm and reliable;
Especially suitable for measuring medium with high viscosity. And it is not sensitive to changes in the viscosity of the liquid being measured;
Easy to install. No straight pipe sections are required before and after the flowmeter. Even if the flowmeter is close to valves, elbows, shrinks, and expansions, there is no need to add straight pipe sections.
In order to prevent the gear of the flowmeter from being stuck by impurities. A filter must be installed upstream of the flow meter
It is a type of flowmeter, and the measurement component is a purely mechanical structure, which is a mechanical flowmeter. Such as oval gear flowmeter.
Take an oval gear flowmeter as an example. Under the action of fluid flow, a pressure difference is formed between the inlet and outlet of the instrument. A pair of oval gears are constantly rotating on the shaft. The cavity between its gears is filled with liquid.
Commonly used fuel flowmeters include turbine flowmeters, circular gear flowmeters, oval gear flowmeters, mass flowmeters, etc.
Industrial oil flow meters measure the volume or mass of oil. Can realize the mutual conversion of volume and mass.
The main industrial oils are hydraulic oil. Gear Oil. Turbine oil. Compressor oil. Refrigeration oil. Transformer oil. Cylinder oil, heat treatment oil, heat transfer oil, etc. Of course, edible oil can also be produced in the industry. In addition, there are greases with lubricating oil as base oil and thickening agent.
Therefore, whether it is a company that uses, trades, or produces oil, it needs to accurately measure the oil flow.
There are many common oil flow meters, such as turbine flow meters, positive displacement flow meters, gear flow meters, mass flow meters, etc.

Crude oil measurement is important to the petrochemical industry. To control costs and improve efficiency. Effective crude oil level measurement regulation has become a challenge for many plants.
If you’re looking for a reliable and accurate way to measure the level of crude oil, the 80G radar level meter is the perfect choice. With its ability to handle various types of liquids and vapors, this meter is ideal for use in oil refineries and other industrial applications. The 80G radar level meter also offers a wide range of features and options, making it the perfect choice for Crude oil measurement application.
What everyone thinks must be the characteristics of the medium of crude oil.
Crude oil, usually referred to as unprocessed petroleum, is a viscous liquid. When the temperature is between minus 50 ℃ and 35 ℃ above zero, solidification will occur, changing from a liquid shape to a solid shape.
From this information, crude oil is viscous and tends to solidify when the temperature drops to the freezing point. Therefore, in order to ensure that the crude oil is always in a liquid state, the storage tank for storing the crude oil may be accompanied by a heating device. This is one of the working conditions.
Of course, there are many factors that can affect the accuracy of crude oil measurement, including the type of tank, the temperature and density of the oil, and the presence of water or sediment in the tank. Inaccurate measurements can lead to costly errors in production, transportation and refining operations.
Crude oil is typically stored in large tanks ranging in size from 10,000 to 50,000 barrels (4.5 to 22.5 million liters). These tanks are often located in remote areas, making it difficult to access them for monitoring and inspection. In addition, the oil in the tanks is typically very hot – up to 150 degrees Fahrenheit (65 degrees Celsius) – and under high pressure. These conditions can make it difficult to get accurate readings of the oil level.
Water and sediment can also accumulate in the bottom of the tank, which can throw off measurements of the oil level. Inaccurate measurement of the crude oil level can lead to over- or under-estimating the amount of oil in a tank, which can have serious consequences for production, transportation and refining operations.
To ensure accurate crude oil measurement, it is important to use a reliable and well-calibrated measuring device. In addition, regular monitoring and inspection of the tank is essential to identify any potential problems that could affect the accuracy of the measurements.
Crude oil measurement – Radar level meter measuring vaulted buffer tank
Distinguished from the shape, Crude oil storage tanks are divided into lying tanks, round tanks, conical tanks, arch-shaped tanks and so on. Distinguished from the use, storage tanks are divided into process tanks and metering tanks.
So, if the radar level meter is used to measure the crude oil in the process, and the crude oil is installed in the vaulted tank. What should you pay attention to Crude oil measurement?
First of all, process tank measurement should pay attention to the selection and installation of radar level meter. The process tank, is not used for direct trading. So the accuracy requirement is not very high. But stability is an aspect that needs attention.
Radar level meter selection, you can consider high-frequency radar level meter. When installing, pay attention to whether there are stirring devices or heating devices in the tank. If there is, pay attention to avoid these obstacles. To avoid causing inaccurate measurement, or even the inability to measure the situation.
From the arch-shaped tank alone, the selection of radar level meter is basically unaffected by the tank, but the installation needs to pay attention to the following. From the arch-shaped tank alone, the radar level meter selection is basically unaffected. But the installation needs to pay attention to the following. Normally, the radar level meter is installed in the vaulted tank. Do not install in the middle of the filling top. To avoid the generation of indirect echoes. Affect the real echo.
Finally, radar level meter to measure crude oil, pay attention to the characteristics of crude oil. Select the appropriate radar level meter model.
According to the information, for a long time in the past, the crude oil vault tank level measurement, are used to manually check the ruler + steel band level meter. As a result, there were often cases of stuck steel belt and stuck shaft.
The result of such a result is inseparable from the characteristics of crude oil. Crude oil has a certain viscosity. If there is a heating device present, there will also be water vapor present. Select radar level meter, as far as possible, choose non-contact radar level meter.
The use of the measured medium is different, the choice of level meter is different. The measured medium used in the tank is different, the choice of level meter is different. The characteristics of the measured medium are different, and the type of level meter is also different.
So no matter what kind of media measurement, we must know the working conditions, know the medium, know the use. This will ensure that the right type, the measurement can be accurate. Liquid level meter to play the maximum role.
4. You can check the readings on the radar level transmitter at any time to see how much crude oil is in the tank.
That’s all there is to it! Using a radar level transmitter is the best way to get accurate readings of the level of crude oil in a tank. If you need any help, don’t hesitate to contact Sino-Inst for assistance.
In the petrochemical industry in order for the crude oil process to run continuously and smoothly care has to be taken when storing raw and finished products. Delivery of the crude oil is via pipeline or ship and stored in a large tank until it is ready for final processing.
Accurate level measurement of products of distillation is essential whilst they are being stored in different sized tanks.
In the past, it was expensive as calibratable measuring devices were implemented for level measurement. Nowadays cheaper and low-maintenance measuring systems are used for small and medium-sized tanks. Products are now usually measured by calibratable flow meters while being moved.
It is important to measure crude oil levels for a number of reasons.
First, crude oil is a valuable commodity, and accurately measuring levels ensures that companies are correctly compensated for the product they are selling.
Additionally, precise measurement is necessary in order to maintain optimal production levels; too little oil could lead to decreased output, while too much could cause equipment failures.
Finally, monitoring oil levels can help to identify potential leaks or other issues with storage tanks and pipelines. By regularly measuring and monitoring crude oil levels, companies can ensure the safety and efficiency of their operations.
There are a few key factors that go into measuring the quality of crude oil. The first is density. This is measured by the American Petroleum Institute (API) and is expressed in degrees.
The second factor is sulfur content. This is important because it determines the amount of pollution that will be produced when the oil is burned.
Finally, viscosity is measured to determine the oil’s ability to flow. This is important for transportation and refining.
Oil is typically measured in barrels, with one barrel containing 42 gallons of oil. To measure the level of oil in a barrel, a ruler or tape measure is inserted into the barrel to determine how much oil is present. The measurements are then converted to barrels using a standard conversion factor.

A high pressure orifice plate flowmeter is a device used to measure the flow of fluids through a pipe. It consists of a plate with an opening in the middle, through which the fluid flows. The plate is placed in the path of the fluid stream and the pressure drop across the plate is measured. This pressure drop is then used to calculate the flow rate. High pressure orifice plates are used in applications where the fluid being measured is under high pressure, such as in steam, oil and gas pipelines.
Applicable measured media is very wide, can be used for almost all gases, steam and liquid flow measurement.
Use pressure up to 32MPa, also can be used for negative pressure.
Bar type flowmeter will be inserted into the center of the pipe probe, the total pressure hole on the direction of the incoming fluid flow. Static pressure hole to the direction of the fluid to flow. The difference between the total pressure and static pressure is the measured differential pressure in the center of the pipe. Then the standard differential pressure at that point is fitted by the wind tunnel calibration curve of the probe.
It is mainly used in high temperature and high pressure high flow rate or ultra-high temperature and ultra-high pressure steam flow meter. It is made of high temperature resistant and impulse corrosion resistant 1Cr18Ni9Ti material.
The complete metal chamber structure is adopted to ensure the strength and steel. So that no damage to the mechanism will occur under the washout of high-speed airflow.
