Features of 76-81GHz FMCW Level Radar

The LM78xx series is an FMCW radar operating at 76-81 GHz, which has a maximum measuring range of 120m and a minimum blind zone of 8cm. It supports 4-wire and 2-wire applications. Higher operating frequency and shorter wavelengths make it ideal for solid applications, including those with extreme dust and high temperature to + 200℃.

The radar consists of an electronic circuit coupled to a lens antenna and flange for quick and easy positioning.

The main benefits of using 78 GHz over devices using lower frequency are:

  • Based on the self-developed CMOS millimeter wave RF chip, a more compact RF architecture, a higher signal-to-noise ratio, and a smaller blind zone are realized.
  • 5GHz working bandwidth means higher measurement resolution and accuracy.
  • 3°antenna beam angle, so the interference in the environment has less impact on the instrument, and the installation is more convenient.
  • Shorter wavelength yields good reflection properties on sloped solids, so aiming towards material angle of repose is usually not necessary.
  • Support remote debugging and remote upgrading to reduce the cost of field personnel.

Communication and Programming

LM78XX supports 485 bus protocol (4-wire), serial-port (2-wire) protocol, and hart (2-wire) protocol. It is very easy to install and configure via an optional graphical local display interface on a PC. Or you can modify the built-in parameters either locally via the pushbuttons. Or you can use a cell phone to control LM78xx via Bluetooth.

The influence of high frequency and low frequency of radar liquid level sensor on measurement

  1. The influence of frequency on measurement

The radar level sensor emits electromagnetic waves through an antenna, and the higher the frequency of the electromagnetic waves. The higher the energy of the electromagnetic wave and the shorter the wavelength, the more obvious the scattering phenomenon. Conversely, the lower the energy, the longer the wavelength, and the energy is not easily absorbed by the gas phase layer.

For an antenna of the same size, a level gauge with a wavelength of 1.2 cm and a frequency of 26 GHz has 6 times higher gain than a level gauge with a wavelength of 3 cm and a frequency of 10 GHz. (Note: Antenna gain is a parameter indicating the degree of concentration of directional antenna radiation).

The received signal diagrams of different frequencies (26-10-6 GHz), the same antenna, dielectric constant, and distance increase are as follows:

The total beam width of the radar level sensor is inversely proportional to the frequency of the device.

Therefore, for an antenna with the same diameter, if the frequency of the radar level sensor is increased, the beam width will be lower than that of a lower frequency device. The narrow beam minimizes the influence of the nozzle, tank wall, and interference.

As shown in the picture (the left side is 6 GHz, the right side is 26 GHz).

At the same time, the measurement range of the radar liquid level sensor is also affected by factors such as frequency, antenna size, the dielectric constant of the liquid, and process conditions.

  1. The application difference between high frequency and low frequency of radar liquid level sensor

When measuring steam, foam, and condensate, choose low-frequency radar first. In most other applications, choose high-frequency radar first for ease of installation.

1) The lower frequency reduces the sensitivity to steam, foam, and antenna contamination. The wave velocity angle of low-frequency radar is wider. It can better deal with the problems of steam, dust, condensation, pollution, and turbulent surfaces.
2) The higher frequency can minimize the impact on the nozzle, tank wall, and interference.

Application of 80G radar level sensor in liquid level measurement with stirring and strong steam

The micro-powder business department of a chemical plant has a variety of tanks, with a field measuring a range of 25 meters. There is a stirrer and heating device inside, and there is high steam when feeding.

As shown in the figure below, when the staff opened the observation cover, strong steam could be seen coming out.

A guided wave radar level gauge is selected before the scene. However, guided wave radar is easily affected by factors such as the corrosiveness of the measuring medium and the viscosity of the medium, and the measurement effect is not good.

Extended reading: guided wave radar level sensor advantages and disadvantages

Later, the customer chose the 80G radar level meter, and the historical trend chart after use is as follows. It can be seen that the liquid level of the four 80G radar level gauges installed on-site can be measured well in several loading and unloading processes.

Extended Reading: FMCW Radar for High Temperature Level Sensor

Why do we have to choose an 80G millimeter-wave radar level gauge for liquid level measurement under high steam and stirring conditions? Can the 26G radar level gauge measure?

Explain briefly. The 80G radar level gauge has a high transmission frequency, has good penetration, and is not affected by steam.

The launch angle of 3° can effectively avoid the interference of the stirring blade;

The unique echo tracking algorithm (echo locking function) avoids reading multiple echoes when the material level is high.

However, when the 26G radar level gauge is in a high-steam environment, the radar wave cannot penetrate the steam or the echo is greatly weakened after the radar wave reaches the interface of the medium, and the measurement is unstable;

In addition, the launch angle of the 26G radar level gauge is generally above 20°, so that the radar wave is easily affected by the stirring blade, causing false alarms;

And when the material level is high, there is no internal steam and the range is large, the echo is very strong, and it is easy to read multiple echoes.

Therefore, the 80G radar level gauge can be selected to obtain a good measurement effect for liquid level measurement under high steam and stirring conditions.

Are you looking for a flow meter for measuring gas volume or mass flow? For Air-O2-N2-CO2 etc.

Every day, in the production process, the production or consumption of various gases may need to be metered. Accurate gas measurement is important work.

Sino-Inst offers volumetric or mass flow meters available for various gases.
If you don’t know how to choose the right Digital Gas Flow Meters. Please contact our sales engineer and we will provide you with a quotation based on your measurement needs.

First, you can start with your measurement needs. Do you need to get the volume flow or mass flow of the gas being measured?

Velocity gas flow meters generally consist of a flow sensor and a display.

For occasions where temperature and pressure change, a pressure gauge (sensor or transmitter), a thermometer (sensor or transmitter), a flow totalizer (temperature and pressure compensation) or a flow computer (temperature, pressure and compression factor compensation) are required.

For occasions with higher accuracy requirements (such as trade natural gas), an online chromatograph is also configured to continuously analyze the components or physical properties of the mixed gas to calculate the compression factor, density, calorific value, etc.

The main industrial applications are:

① Turbine flowmeter:
When the fluid flows through the turbine flow sensor, the turbine is forced to rotate under the action of the fluid thrust. Its rotational speed is proportional to the average flow velocity of the pipeline. The rotation of the turbine periodically changes the reluctance value of the magnetoelectric converter. The magnetic flux in the detection coil follows Periodic changes occur, generating periodic electrical pulse signals. In a certain flow (Reynolds number) range, the electrical pulse signal is proportional to the volume flow of the fluid flowing through the turbine flow sensor.

②Vortex flowmeter:
A bluff vortex generator is placed in the fluid. The fluid is alternately separated on both sides of the vortex generator to release two regular rows of alternating vortex streets. In a certain flow (Reynolds number) range, the separation frequency of the vortex is proportional to the volume flow of the fluid flowing through the vortex flow sensor.

③ Precession turbine flowmeter:
When the fluid passes through the spinner composed of helical guide vanes, the fluid is forced to rotate strongly around the centerline to form a vortex turbine. The center of the vortex precesses along a conical spiral when passing through the enlarged tube. In a certain flow rate (Reynolds number) range, the precession frequency of the vortex flow is proportional to the volume flow of the fluid flowing through the precession vortex flow sensor.

④Time difference ultrasonic gas flowmeter:
When ultrasonic waves pass through a flowing fluid, within the same propagation distance, their propagation velocities are different in the forward flow direction and the countercurrent direction. In a wide range of flow (Reynolds number), the time difference is proportional to the volumetric flow (average velocity) of the fluid being measured in the pipe.

The gas volumetric flowmeter is a mechanical instrument. It is generally composed of a measuring body and a totalizer. For occasions where temperature and pressure change, a pressure gauge (sensor or transmitter), a thermometer (sensor or transmitter), a flow rate Totalizer (temperature and pressure compensation) or flow computer (temperature and pressure and compression factor compensation).

Inside the positive displacement flowmeter, there is a fixed large space and a set of rotating bodies that divide the space into several small spaces of known volume. Such as waist wheel, membrane, drum, scraper, oval gear, piston , screw, etc.

The rotating body rotates continuously under the action of the fluid pressure difference, and continuously discharges the fluid from a small space of known volume.

According to the number of rotations of the rotating body in a certain period of time, the volume of fluid flowing through can be obtained.

In the standard state, the volume flow calculation formula of the positive displacement flowmeter is the same as that of the velocity flowmeter.

Differential pressure flowmeter is based on Bernoulli equation and fluid continuity equation. According to the throttling principle. When the fluid flows through the throttling part (such as standard orifice, standard nozzle, long diameter nozzle, classic venturi nozzle, venturi Sharp nozzle, etc.), a pressure difference is generated before and after it. This differential pressure value is proportional to the square of the flow.

Among the gas flowmeters, the standard orifice plate throttling device differential pressure flowmeter is the most widely used because of its simple structure, low manufacturing cost, most complete research and standardization.

  • Open Channel Flowmeters

The gas velocity in the pipeline is the basis for calculating the gas flow. The way to measure the gas flow rate is direct measurement or conversion through pressure measurement.

Enterprises usually use Pitot tubes (or dynamic pressure velocimetry tubes) to measure the dynamic pressure of the fluid in the pipeline first, and then calculate the flow velocity and average flow velocity at this point (the average flow velocity should be used to find the gas flow).

Because the velocity measuring tube is used to measure the velocity of the pipeline, it is only the local velocity of a certain point on the pipeline section. The flow velocity at each point on the pipeline is not the same. It is necessary to measure the flow velocity at multiple points on this section. Find the average dynamic pressure to calculate the average flow velocity.

There are many types of gas flow meters. Such as common thermal mass flowmeters, vortex flowmeters, differential pressure flowmeters, etc. Different kinds of gas flow meters are based on different working principles.

The working principle of gas flowmeter, the common types are as follows:

  1. Thermal gas mass flowmeter: designed based on the principle of thermal diffusion, the instrument uses the constant temperature difference method to accurately measure the gas. The sensor section consists of two reference grade platinum resistance temperature sensors, suitable for the measurement of all gas flow meters (except acetylene)
  2. Precession vortex flowmeter: adopts the latest micro-processing technology. It has the advantages of strong function, wide flow range, operation and maintenance verification, convenient installation and use, etc. It is widely used in various gases such as petroleum, chemical industry, electric power, metallurgy, coal, etc. Measurement of liquids.

It can be widely used in petroleum, chemical, metallurgy, organic liquid, inorganic liquid, liquefied gas, city gas pipeline network, pharmaceutical, food, papermaking and other industries.
  4. Vortex flowmeter: The principle of Karman vortex is adopted. A triangular column-shaped vortex generator is set in the fluid, and regular vortices are alternately generated from both sides of the vortex generator. This vortex is called Karman vortex, and the vortex flowmeter is the current One of the main flow meter products in the world. It is widely used in petroleum, chemical, metallurgy, heating and other departments. Detect and measure the flow of liquid, gas and steam.
  5. Differential pressure flowmeter: Differential pressure flowmeter is based on Bernoulli equation and fluid continuity equation. According to the throttling principle, when the fluid flows through the throttling part (such as standard orifice, standard nozzle, long Diameter nozzles, classic venturi nozzles, venturi nozzles, etc.). There is a pressure difference before and after it, and this differential pressure value is proportional to the square of the flow. Among the gas flowmeters, the standard orifice plate throttling device differential pressure flowmeter has a simple structure and low manufacturing cost. It has been standardized and has been widely used.

Mass flow meter directly measures the mass flow of the medium passing through the flow meter. It can also measure the density, temperature and viscosity of the medium

Mass flow meter is a flow measuring instrument that measures the mass flow in the pipeline. The volume of a fluid is a function of fluid temperature and pressure and is a dependent variable. The quality of a fluid is a quantity that does not change with time, space temperature, and pressure.

A pure totalizer is not a flow meter.

Usually, flow meters measure instantaneous flow. If you need to know the total amount of flow, you need to use a totalizer.

A complete flow detection system includes several parts such as sensing, transmission, calculation, integration, display, etc. Each part can be an independent instrument. It is also possible to integrate several functions into one watch.

Many flow totalizers on the market now integrate calculation, totalization, and display. It includes most of the functions of the flow system. Some manufacturers set the totalizer and other parts as flow meters and use the name of the complete set on the totalizer. If you buy the totalizer alone, you will see that the name is flowmeter.

Our flow totalizers support the display of various commonly used flow units. Paperless recorders contain more units for flow, pressure, temperature, etc.

For example, with the following common units: ℃, Kgf , Pa, KPa, MPa, mmHg, mmH2O, bar, t/h, Kg/h, L/h, m³/h, Nm³/h, t/m, Kg/ m, L/m, m³/m, Nm³/m, t/s, Kg/s, L/s, m³/s, Nm³/s, t, Kg, g, Nm³, m³, L, KJ/h, KJ/m, KJ/s, MJ/h, MJ/m, MJ/s, GJ/h, GJ/m, GJ/s, KJ, MJ , GJ , V, A, KW, Hz, %, mm, rpm;

Flow meter totalizer calculation

Flow meter totalizer calculation refers to the collection of this flow at a fixed frequency.

If the acquisition frequency is 10hz, that is, 10 acquisitions per second. Accumulate the data collected each time, and divide the accumulated number by 10 to get the flow per second.

If the flowmeter is working at the maximum flow rate, we assume that the value corresponding to 20ma is 65535 (generally, the PLC analog quantity does not have such a high accuracy, so how much depends on the module).

Then double-word operations can meet the requirements. First convert the analog input value into a double word. Accumulate again. After 10 times, the accumulated value is divided by 10 and then transferred to another register. This register is the real cumulative amount.

Flow totalizer working principle

The intelligent flow totalizer is composed of four parts: measurement loop, digital panel meter, regulator and power supply.

The stabilized power supply converts the 220V power supply into a stable DC voltage as the other part of the power supply. The measurement loop processes the signal (voltage, current, etc.) sent by the flow transmitter into a voltage signal.

After A/D conversion, the signal is sent to the JC-775 dedicated central processing unit for processing, and not only to the digital panel meter. Moreover, it must be sent to the regulator, and the control or alarm signal will be output according to the regulation law after comparing with the set value.

How to realize the flow accumulation function in PLC?

First of all, it must be clear that the accuracy of using PLC for flow accumulation is far inferior to electromagnetic flowmeters and other flowmeters and flow totalizers that have their own accumulation function.

For flowmeter converters with accumulation function, the flow accumulation output of the general flow converter is pulse output. High-speed counting can be performed through the high-speed pulse input terminal of the PLC to obtain the cumulative flow.

For flowmeters with only instantaneous flow output, the flow cumulative addition operation is considered in PLC.

When doing flow accumulation in the PLC, you should not use a timer to do it. Because the timer is affected by the PLC scan cycle. It is impossible to be very accurate, and the error of the accumulated data is very large.

At present, general medium and large PLCs directly or indirectly provide the “Totalizer” function block. The essence is to simply accumulate the instantaneous flow of each acquisition cycle.

Read More about: Inline gas flow meter

Target flow meter measures oxygen:

The main measurement medium of this flowmeter is high viscosity, many impurities, easy to block, high temperature, low temperature, and strong corrosion. Oxygen is a pure gas, a small molecule gas, and its flow rate is slow. The target flowmeter does not meet its measurement characteristics.

Differential pressure flow meters (Bar-type series flow meters, orifice plates, wedge types, nozzles, V cones, etc.) measure oxygen:

All of them belong to a kind of throttling device. When measuring, the pressure is taken through the pressure taking port, and then converted into a flow signal output by the transmitter. In the process of converting the flow signal, the transmitter is prone to zero drift, and the stability of the flow is difficult to guarantee.

The pressure loss is larger than other flow meters, and it is difficult to accurately measure under low pressure and low flow rate conditions. Easy to get dirty and easy to block, large maintenance, can be used for general process control.

When there is no interference on site, the accuracy is greater than 2.5%, and the installation of large pipe diameter is time-consuming and laborious.

Metal tube float flowmeter measures oxygen:

This flowmeter is a mechanical flowmeter designed to measure small flow gases, with a measurement accuracy of 2.5%. There is no advantage in measuring large pipe diameters, hydrogen, and oxygen.

The flow range of DN300: 600~6000m3/h. The upper limit of flow can only reach 6000 cubic meters per hour, which cannot meet the on-site flow. Large pipe diameters are expensive and troublesome to install.

renewable energy source-biogas

At present, the use of biogas is mainly concentrated in three major fields: rural areas, aquaculture, and industry.

Utilization of rural biogas
The comprehensive utilization of rural biogas can effectively solve the problem of living energy for farmers. The existing plant straw and animal manure in rural areas are used as raw materials. Use facilities such as biogas digesters to produce biogas after long-term fermentation. Provide farmers with gas, lighting, organic fertilizers.

Utilization of biogas in aquaculture
Livestock and poultry manure is put into the biogas project to produce biogas after fermentation. After the manure is fermented, it can be directly used as crop fertilizer, fish farming, pig feeding, seed soaking, etc. Promote the integration of agricultural planting and breeding. The main utilization methods are as follows: First, to provide gas for surrounding residents. The second is to provide electricity for the farm through power generation, and the remaining electricity will be connected to the grid.

Utilization of biogas in industry
The utilization of biogas in the industrial field is mainly concentrated in papermaking, brewing, food processing, sewage treatment and other industries. Industrial waste is used as raw material for fermentation to produce biogas. Mainly power generation and heat supply. Biogas can be used for internal combustion engine power generation, combustion support of large coal-fired boilers or to replace raw coal. Use small boilers to produce steam, etc.

Featured Biogas Flow Meters

Purpose of biogas flow measurement

In the process of biogas production and use, it needs to be flow metered. The main purposes are as follows:

  • Provide reference data for biogas station. The purpose of installing flow meters in biogas supply stations is to provide basic data for the scheduling and control of biogas.
  • Check the efficiency of fermentation tanks or landfills. Know the efficiency of the fermentation tank through the biogas flow. If the flow fluctuates unexpectedly, you can check the status of the fermentation tank in time.
  • Control the combustion efficiency of the boiler. When a biogas boiler is burning, it is necessary to understand the flow of biogas to control the ventilation of the boiler. Excessive ventilation will reduce the furnace temperature. The ventilation rate is too low and the gas cannot be fully burned, causing waste and pollution.
  • Control greenhouse gas emissions. Both CH4 and CO2 in biogas are greenhouse gases. Among them, CH4 is a greenhouse gas that is more harmful than CO2.
  • Charges for civil biogas metering. Civil users install flow meters mainly for metering charges, and the management department conducts cost accounting.

Difficulties in biogas measurement

Biogas is a kind of gas that is very difficult to measure. It has the following characteristics:

  • Very low pressure: the original biogas from the fermentation tank usually does not exceed 0.1 kg (10kPa).
  • Composition changes: Biogas is composed of a variety of mixed gases. The composition of the biogas produced will fluctuate greatly depending on the raw materials for gas production.
  • Large flow fluctuations: With changes in biogas raw materials, bacteria conditions, temperature fluctuations, etc., the output biogas flow rate will also vary greatly, so the flowmeter is required to have a larger turndown ratio.
  • Water vapor: Biogas is produced by the fermentation of biomass, and the water in the biomass will be carried into the biogas. Therefore, the biogas usually contains saturated water vapor.
  • Corrosive: Biogas usually contains H2S, although the content is low. But H2S will form corrosive hydrosulfuric acid after encountering water vapor. There is a greater potential for corrosion of metering components.
