The Use of Beer Flow Meter in Beer Production Process

In the main technological process of beer production. For effective control in the production process. It is necessary to measure and control the intermediate raw materials – wort, sake in semi-finished products, raw juice wine in high-concentration dilution process, sterile carbonated water, final product filling and waste water generated during production.

Raw material allocation: During the preparation of raw materials for beer production. The main measurement parameters are weight and level.

Wort production: Wort is an important intermediate raw material for beer production. Its measurement involves the handover settlement between the front and rear processes (workshops), which is extremely important. Especially when the front and rear process workshops are separately accounted for. The measurement results are related to the completion of the respective production and economic indicators. Therefore, this measurement point is very important and sensitive, and accuracy is its primary indicator.

Wort has a certain viscosity, but there is no difficulty in the measurement of electromagnetic flowmeter. What needs to be considered is corrosion during the process. The flowmeter used at this measurement point can consider the electromagnetic flowmeter with PTFE lining (or PFA) and stainless steel electrode. It can prevent the corrosion of dilute hydrogen peroxide and alkaline water. Usually the diameter is between 50 and 100mm. The diameter of the flowmeter can be determined according to the flow rate and the matching process piping.

Fermentation: Sake that has been fermented and filtered. It will be transported to the next process through the pipeline – packaging. It also involves the custody transfer of the two departments. Accurate measurement of sake is also extremely important, otherwise unnecessary disputes will arise. The requirements for flow meters are similar to those for wort metering.

High concentration dilution: due to different production processes. Some beers are produced by blending high-strength ale. This requires strict control of the ratio of high-concentration original wine and sterile carbonated water. Guarantee the degree of beer after mixing.

Beer Flow Meter System

In each production line, two electromagnetic flowmeters are required for proportional flow control. Generally, the diameter of the flowmeter for measuring wine is 50-100mm. The flowmeter for measuring water is 20-50mm. Depends on production scale. In order to ensure that the instrument has a high measurement accuracy. It should be ensured that the fluid velocity is above 1m/s. Make the flow measurement in the best working range of the instrument. At the same time, the time constant of the flowmeter should also be set smaller, generally 1 to 3s. In order to improve the sensitivity of the control and ensure the accuracy of the proportioning.

Flow meters in the production process of the beer industry have their own special requirements. For example, it is necessary to avoid the reproduction of bacteria, to facilitate frequent cleaning and to withstand the disinfection of corrosive alkaline water and hydrogen peroxide under higher temperature conditions. Specific requirements are as follows:

  1. The sensor measurement circuit is simple. There are no obstructions and parts that tend to retain media.
  2. All the parts and materials in contact with the medium meet the requirements of food hygiene. Such as compliance with FDA (US Food and Drug Administration), EHEDG (European Health Equipment Design Organization) requirements.
  3. The parts in contact with the medium can withstand the temperature crash and corrosion when cleaning with steam, alkaline water and hydrogen peroxide.
  4. When used in filling process, it should have fast response performance and high measurement accuracy.
  5. Can adapt to low temperature (about 2 ℃) and humid working environment.

Vortex flowmeter for the volume of wet gas

When using a vortex flowmeter to measure gas flow, many wet gases are often encountered, such as wet air, wet gas, and wet chlorine.

Read more about: How Vortex Flow Meter measure efficiently? For steam, gas, liquid 

Physically, the commonly used mixture of water vapor and gas is called a mixed gas with certain humidity, that is, wet gas.

In wet gas, the density of water vapor constitutes a part of the density of the wet gas. However, in many cases, what needs to be measured and calculated is the volume or mass of dry gas. For example, this is the case when determining the heating value.

There are also wet air, wet chlorine, etc., as industrial raw gas. What companies need is a dry gas, so the “moisture” of these wet gases should be squeezed out when measuring, in order to better control the quality of products. Calculate the cost of the product.

The density of the wet gas is composed of the dry part of the wet gas and the water vapor contained in the wet gas. When the vortex flowmeter is used to measure the flow of the wet gas, because the vortex flowmeter only reflects the wet gas in the working state The volume flow rate cannot distinguish between the dry part of the wet gas and the amount of water vapor. Therefore, the volume flow measured by the vortex flowmeter is the volume flow of all wet gas. If only the volume flow rate of the dry part of the wet gas needs to be measured, the volume flow rate of the water vapor part should also be subtracted.

When using a vortex flowmeter to measure the flow of wet gas, because the vortex flowmeter only reflects the volume flow of the wet gas under working conditions, it cannot distinguish the dry part of the wet gas and the amount of water vapor.

Therefore, the volume flow measured by the vortex flowmeter is the volume flow of all wet gas. If only the volume flow rate of the dry part of the wet gas needs to be measured, the volume flow rate of the water vapor part should also be subtracted.

Precautions for measuring wet gas with vortex flowmeter

(1) Instrument selection

For the wet gas in the industrial gas, when the water vapor reaches the saturated state, water in the free state will appear in the pipeline. This state has a certain impact on the normal operation of the thermal and ultrasonic vortex flowmeters.

If the water in the free state adheres to the surface of the thermal detection element, it will affect the thermal conductivity of the thermistor element. It will affect the detection sensitivity and the lower limit of the range of the instrument.

If the water in the free state adheres to the surface of the ultrasonic transducer, it will also affect the transmission and reception of ultrasound. It will not only affect the transmission efficiency of ultrasound, but also the effect and sensitivity of ultrasound reception.

If this free water stays in the acoustic isolation annulus between the ultrasonic transducer and the tube wall, it will cause an acoustic “short circuit” phenomenon. Ultrasonic waves will diffract along the measuring tube wall and reach the opposite receiving transducer. The normal operation of the instrument was severely damaged.

If the water in the free state passes through the sound beam in the form of water droplets or mist, it will scatter and modulate the sound beam. It will become a serious random interference and affect the stability of the measurement.

Due to the above influences, when measuring wet gas flow, vortex flowmeters with force-sensitive detection should be used. For example, stress vortex flowmeters and capacitive vortex flowmeters. Because of the moisture in the wet gas and the free water, It has little influence on force detection and transmission.

(2) Prevent the corrosive effect of wet gas

Some gases such as chlorine, hydrogen sulfide, and so on. There is a certain degree of corrosiveness in the dry state, but the corrosiveness is not very strong. Once it becomes wet gas, its corrosive effect increases sharply. When selecting the meter, the vortex flowmeter that can withstand the corrosive effect of the medium should be selected in a targeted manner to prevent the invasion of wet gas.

(3) Installation method

When measuring wet gas with a vortex flowmeter.

If installed horizontally, the measuring section should be increased appropriately. Prevent saturated water from staying in the measuring tube of the instrument.
If installed vertically, the vortex flowmeter should be at a certain height from the horizontal pipe section.

(4) Operation and maintenance of the instrument

To prevent free water from accumulating in the pipe, a drain valve or drain valve should be installed at the lowest point of the pipe. Evacuate the sewage and dirt accumulated in the pipe regularly.

Industrial LPG/Propane flow meter

Digital LPG/Propane flow meter

A propane flow meter refers to a flow meter that can measure the volume or mass flow of propane gas. Also often called LPG gas flow meter.

Featured Inline Propane Flow Meter

Propane is also generally referred to as liquefied petroleum gas (LPG). So what is the difference and connection between propane and LPG? Next, let’s take a look together.

Propane VS LPG

Because propane is one of the main components of liquefied petroleum gas.

Propane is pure, and liquefied petroleum gas is a mixture.

LPG is a by-product obtained during the catalytic cracking and thermal cracking of crude oil in refineries.

The main source of commercial LPG is the processing and refining of natural gas and oil. The raw materials usually contain excessive amounts of propane and butane. To prevent these two substances from condensing in the high-pressure exhaust pipe, they must be removed.

In the petroleum refining process. LPG is collected by titration from the dissolved crude oil mixed with a lighter specific gravity. At the same time, it can also be produced by the molecular fission of heavy hydrocarbons. Therefore, LPG is considered a subsidiary product. Its exact composition and characteristics usually vary from source to source.

  • Small size and lightweight, it is more convenient for offline calibration;
  • The measurement signal can be displayed on the spot or transmitted remotely as required;

Why is Precession Vortex Gas Flowmeter the right Propane flow meter?

Before that, people would use vortex flowmeters to measure propane.
Although the precession vortex flowmeter and vortex flowmeter are all fluid vibration flowmeters. However, the precession vortex flowmeter has the following advantages:

  1. The generated vortex signal is stronger than that of a vortex flowmeter, so the lower limit Reynolds number is lower. When measuring gas flow, the lower limit flow rate can be as low as (1.5~2) m/s.
  2. Because the vortex signal generated by the flowmeter is stronger than that of the vortex flowmeter. It is less affected by the upstream choke than the vortex flowmeter. Therefore, the length of the upstream straight pipe is much shorter.
  3. The meter coefficient K is 1 to 2 times larger than that of the vortex flowmeter.

Common Industrial Fuel

Fuel oil refers to light distillate fuel oil and heavy distillate fuel oil obtained after crude oil is distilled and processed in a refinery. The former mainly includes gasoline, diesel and jet fuel used in crawling machinery and aircraft internal combustion engines. The latter is mainly used as boiler fuel for steam furnaces and various heating furnaces.

Fuel oil is a fuel used for engine operation, mainly divided into gasoline and diesel.

There are two main types of fuel for automobiles, gasoline and diesel.

The aircraft uses aviation kerosene.

The classification of gasoline is based on the octane number it contains, such as 90#, 97#, etc. The higher the octane number, the lower the probability of deflagration produced by the car, and the better it is for the engine. Therefore, most high-end cars use higher-grade gasoline.

The classification of diesel is based on its freezing point. 0# means that when the temperature is lower than 0 degrees Celsius, it will condense into a solid. The same reason -10# means that it condenses into a solid at -10 degrees Celsius. This is the reason why the diesel cars in the northern winter have a lower label to prevent the fuel from being frozen.

Marine fuel flow meter-fuel flow meter for boat

Marine Fuel Flow Meter is a positive displacement flow meter specially used for measuring marine fuel oil (MFO). With the highest accuracy.

Large-caliber oval gear flow meters, such as 6 inch, 8 inch (DN150, DN200) etc. It is commonly used to measure the flow of oil such as marine fuel, aviation fuel, and diesel. Oval gear flowmeter is a commonly used positive displacement flowmeter. Can indicate cumulative flow, instantaneous flow, single flow, etc. on site.

Fuel flow meter for diesel

Three kinds of flow meters are commonly used to measure diesel:
The first is an oval gear flow meter, which is also commonly used, with an accuracy of 0.5.
The second type is liquid turbine flowmeter, the accuracy can be 0.5 or 0.2, flange or thread connection
The third type is float type, installed vertically or horizontally, with an accuracy of 1.5.

Although they all measure the flow of diesel oil products, the difference is still very large.

For example, dual-rotor flowmeters and oval gear flowmeters can measure diesel fuel. And various parameters are in line with the measurement range of these two flowmeters.

However, the measurement range of the dual-rotor flowmeter is very large and the noise is very low, and the accuracy is also high. Under the conditions of high precision and low precision, the liquid flow range is very large. However, the minimum pipe diameter is 25mm and the maximum is 300mm;

The oval gear flowmeter is different. The minimum pipe diameter is 6mm and the maximum is 200mm.

And the flow range is very wide. The most important thing is that the price is relatively cheap, which is the best choice for most customers.

How does micro motion flow meter work?

The micro-motion mass flowmeter is a flowmeter made according to the Coriolis acceleration theory. There is a straight tube that rotates in a plane around a fixed axis O at an angular velocity w, and a particle in the tube moves outwards along the straight tube at a speed v. Because The mass point m is in a system with both rotational motion and linear motion, so it will obtain two accelerations.

Serving size:

① Centripetal acceleration a, its value is rw^2 (r is the distance from the particle m to the axis O), and the direction points to the axis O.
② Tangential acceleration ac, its value is 2uw. The direction is perpendicular to a, it comes from the rotating pipe. At the same time it produces a reaction force to the pipe. This reaction force is the Coriolis force. Its calculation formula is:

F=2muw —————-(3-8)

Where:
F is Coriolis force, N;
w is the angular velocity, 1/s;
u is the radial velocity in the rotating system, m/s,
m is the mass of the moving object, kg.

If the density of the fluid is p, the tangential Coriolis force on any section of pipe △x is:

△F=2pA△xuw ———(3~9)

Where:
A is the cross-sectional area of ​​the pipe.

In the formula (3-9), pAu is the natural flow rate of the fluid, set as QM’, then the formula (3-9) can be expressed as:

△F= 2w△xQm————-(3-10)

From the above equation, we can know the mass flow Qm as long as the Coriolis force △F is measured. This is the measuring principle of micro-motion mass flowmeter.

Questions

Clamp-on flow meters can be installed on new or existing pipes and sit on the outside of the pipe. This saves time and money since no cutting into the pipe is required. 

Clamp on Ultrasonic Flow Meter adopts the measurement principle of time difference method. It uses the ultrasonic wave emitted by the sensor to propagate in the flowing fluid. The sound wave propagation speed in the downstream direction will increase, and the backward direction will decrease. In the same propagation distance, there will be different transmission times. According to the difference between the transmission time and the measured The relationship between fluid velocity measures the fluid velocity.
The flow rate of the fluid is different in different positions in the tube. The flow rate in the center of the tube is faster than the flow rate near the wall of the tube. The flow velocity distribution of the fluid in the pipeline can be represented by the flow velocity cross-sectional distribution diagram.
By setting the flowmeter and considering the cross-sectional distribution of the flow velocity, the average flow velocity can be calculated. Then the volume flow of the fluid can be obtained according to the cross-sectional area of the pipe.

Notes:
V measure fluid velocity
M ultrasonic reflection times
D pipe diameter
θ The angle between the ultrasonic signal and the fluid
T up The time when the downstream sensor transmits the signal to the upstream
T down Time from upstream sensor to downstream
ΔT = T up – T down

Read more about: Ultrasonic flow meters types & technical guide

Ultrasonic flowmeters use sound waves to determine the velocity of a fluid flowing in a pipe.
At no flow conditions, the frequencies of an ultrasonic wave transmitted into a pipe, and its reflections from the fluid are the same.
Under flowing conditions, the frequency of the reflected wave is different, due to the Doppler effect.
When the fluid moves faster, the frequency shift increases linearly.
The transmitter processes signals from the transmitted wave, and its reflections to determine the flow rate.

Common industrial refrigerants

  1. Water

Using water as a refrigerant is a low-cost solution that is completely non-toxic, easily available and environmentally friendly. Read more about: Digital Water Flow Meters

  1. R134A Hydrofluorocarbon

This is a hydrofluorocarbon (HFC) and haloalkane refrigerant, commonly known as halothane or Freon 134A. As a refrigerant, it has completely stable thermal characteristics, low toxicity, non-corrosiveness and non-flammability. It is widely used in automobile air-conditioning units and industrial chillers.

  1. R744 carbon dioxide
    The use of carbon dioxide as a refrigerant is advantageous because it is non-flammable and non-toxic.
  2. R717 ammonia

Ammonia (R717) is a refrigerant and is a halogen-free chemical. This is the most commonly used refrigerant in chillers. It has the highest heat absorption rating, which makes it ideal for use in small portable chillers without the need for large cooling equipment.

  1. HCFC

This is a group of refrigerants composed of HCFC compounds. They have a high GWP and are very toxic. Examples of refrigerator refrigerant types in this group include R2, R123, R124, and R151.

  1. HCS

Hydrocarbons are another refrigerant used in domestic and industrial refrigeration. Common refrigerant hydrocarbons are R600A (isobutylene) and R290 (propane).

These refrigerant types are highly flammable and therefore require careful special installation. As we all know, propane has no potential for ozone depletion, so it is suitable for environmentally friendly industrial chillers.

7. 407C Rand

The combination of hydrofluorocarbon difluoromethane (R32), pentafluoroethane (R125) and 1,1,1,2-tetrafluoroethane (R134A) will respectively provide heat, reduce flammability and reduce pressure. This refrigerant is considered to be the most suitable substitute for the R-22 refrigerant system, which will be phased out in 2020.

  1. R404A

If the cooling process requires medium and low temperature refrigerants, R404A should be considered. This is a mixture of hydrocarbons that can be used in various commercial environments, such as supermarkets and cold storage rooms.

9. R410A type

For general air conditioners, R410A is an azeotropic mixture of hydrofluorocarbons that can be used. It has no harmful effect on the ozone layer. With the phasing out of R22 refrigerant, it has become more and more popular.

  1. R448A type

This is a non-flammable HFC mixture used to replace R22 and R404A in domestic and commercial refrigeration systems. It is toxic and requires careful handling, installation and storage.

  1. R449A type

R449A is another HFC mixture with similar composition to R448A. It is used as a substitute for R404A and R507A refrigerants in medium and low temperature applications.

One of the main advantages of R449A is that it can be easily retrofitted in old refrigeration systems or installed in newer models. Another advantage is its environmental friendliness and low GWP.

Gear flow meter working principle

Gear flow transmitter is a type of positive displacement flow transmitter. It is a high-precision transmitter for measuring volume flow.

With the flow of the medium, the gears mesh and rotate. Under the action of the fluid flow, a pressure difference is formed at both ends of the instrument inlet and outlet. There is no need for a power supply. A pair of gears rotate freely. The cavity between the gears is filled with liquid. Discharge and measure the number of revolutions of the gear to know the flow of liquid and liquid flowing through the instrument.

Figure 1 Schematic diagram of fluid flow

The rotation speed of the round gear transmitter is detected by the sensor coil in the signal amplifier mounted on the watch case. The signal amplifier is not in contact with the measured medium. When the transmitter gear cuts the magnetic field lines generated by the permanent magnet in the housing, it will cause the magnetic flux in the sensing coil to change.

The sensing coil sends the detected magnetic flux periodic change signal to the preamplifier, amplifies and reshapes the signal, generates a pulse signal proportional to the flow rate, and sends it to the unit conversion and flow integration circuit to obtain and display the cumulative flow value. At the same time, the pulse signal is sent to the frequency current conversion circuit, which converts the pulse signal into an analog current quantity, and then indicates the instantaneous flow value.

The round gear transmitter has high machining accuracy and precise installation. The rotation of the gear is scanned non-contact, and each tooth generates a pulse with a very high resolution. Cylindrical gear transmitters can measure very small flow and quantify the small volume of liquid.

Oval Gear Flow Meter

Oval gear flow meters (also known as displacement flow meters, gear flow meters) are a type of positive displacement flow meters, which are the most accurate type of flow meters. It uses a mechanical measuring element to continuously divide the fluid into a single known volume part, and measures the total flow volume according to the number of times that the metering chamber is filled and discharged with the volume part of the fluid successively and repeatedly. The oval gear flowmeter can be made of different materials (cast iron, cast steel, 304 stainless steel, 316 stainless steel), and is suitable for flow measurement in the chemical, petroleum, pharmaceutical, electric power, metallurgy and food industries.

The measurement principle of the gear of the Cylinder Gear flow meter is similar to that of the oval gear flow meter. But the gear shape is different.

Oval Gear Flow Meter Advantages and Disadvantages

The oval gear flowmeter uses the principle of volumetric type. Suitable for testing various viscous liquids. Flow measurement of heavy oil, polyvinyl alcohol, resin and other high-viscosity media.

Advantages:

  1. The measurement accuracy of the oval gear flowmeter is high. The basic error is generally ±0.5%R. Special ones can reach ±0.2% R or higher. It is especially suitable for use in the field where high-precision measurement is required.
  2. It has no influence on the measurement accuracy when measuring the distortion of the flow velocity field of the rotating flow and the pipeline choke. There is no requirement for the front straight pipe section.
  3. The oval gear flowmeter can be used to measure high-viscosity fluids. Wide flow range. It is generally 10:1 to 5:1. Special ones can reach 30:1 or greater.
  4. With direct reading of on-site flow. It can measure the cumulative total without external power supply. The display is clear and the operation is convenient.

The oval gear flowmeter is a combination of measuring elements. The indirect method of volumetric flow measurement. Compared with other flow meters that use velocity to derive flow. Oval gear flow meters have the following disadvantages:

  1. The design of the measurement structure is complicated. Large and bulky. In particular, the flowmeter with a larger caliber is bulky. Compared with other general flow meters (such as orifice flow meters, float flow meters, electromagnetic flow meters, vortex flow meters). The measured medium type, medium working condition (temperature, pressure), and caliber are relatively limited. The scope of adaptation is narrow.
  2. Not suitable for high and low temperature occasions. Because of the thermal expansion and deformation of parts at high temperatures, the material becomes brittle at low temperatures. The usable temperature range is -30~+180℃. The maximum pressure is 10MPa.
  3. The oval gear flowmeter is only suitable for clean single-phase fluids. When the fluid contains particles or dirt, a filter must be installed upstream. Not only increases the pressure loss, but also increases the maintenance work. If measuring liquids containing gas, a gas separator must be installed.
  4. Poor safety performance during measurement. If the measuring element is stuck in motion, the fluid cannot pass through. The cut-off piping system cannot be used.
  5. During the measurement process, the pulsation caused by the flow of fluid during the measurement process. Large-diameter flowmeters can also generate noise. Even the pipes vibrate.
