Application case|120G FMCW radar level meter is applied to the measurement of liquid level in chemical reactor

 

In chemical reactors, can the liquid level be monitored for complex working conditions such as small range, rapid stirring, and steam? How to provide an effective solution for liquid level measurement?

 

Our 120G frequency modulated radar level meter has a transmission frequency of 120~130GHz and a 10GHz frequency sweep bandwidth. It only takes 80 ms to complete a complete measurement and calculation process for a distance of 100m. Non-contact measurement, strong anti-interference ability, can overcome the influence of steam, foam and stirring on the measurement, and accurately measure the liquid level in various small-range storage tanks and reactors.

Let us take a look at the actual performance of the radar level gauge DCRD1000B1 on the chemical reactor.

On-site working conditions and instrument parameters

Chlorination workshop of a chemical company:

Instrument parameters:

Model: DCRD1000B1

Medium: certain chloride, with chlorine gas; 

Range: 4.5 meters; Process connection: DN150 PN16;

Process pressure: 1.0Mpa; Process temperature: 100°C;

On-site working conditions: The tested device is a reaction kettle with liquid chlorine and steam. The tank is stirred in the middle, and the speed is about 120 rpm. There are three baffles inside the tank.

Others: other high-frequency radar level gauges have been tried on site, and the level changes during mixing cannot be measured。


Measurement process

The most difficult point in the measurement of this working condition is that the stirring speed in the tank is too fast, and the amplitude and frequency of the liquid level fluctuation are large. The radar signal is easily interfered and interrupted during stirring. The measurement effect of the 120GHz frequency modulation continuous wave radar level meter is as follows:

Measurement results and analysis

After field test, the 120G frequency modulation radar level gauge has good measurement results, and overcomes the following measurement difficulties in complex working conditions:

 

1)The reactor has a relatively small volume, stirring in the middle, and there are three baffles in the middle of the tank. The radar signal is best to avoid obstacles. Therefore, the reactor basically requires the launch angle of the radar to be smaller. The launch angle of the 120G radar level gauge Only about 1°, which meets the requirements of working conditions.

 

2)The stirring rate is very fast, and the difference in liquid level fluctuation is about 1m. During the stirring process, the normal output of the radar level gauge must be ensured, and there should be no signal interruption or signal bounce.

 

3) There is liquid chlorine and steam in the reactor, which need to be anti-corrosion, and the influence of steam on the measurement should also be reduced.

 

In summary, this radar level gauge has been successfully applied to the level measurement of the solution in the chemical reactor, demonstrating the reliability and stability of the instrument under complex working conditions, and achieving a satisfactory measurement effect for users.

    Radar level instruments measure the distance from the transmitter/sensor (located at some high point)to the surface of a process material located further below in much the same way as ultrasonic level sensor, by measuring the time-of -flight of a traveling wave and then determine the level of the process material. They are regarded as continuous level measurement devices because they continue to measure level even as the level of the liquid in the vessel changes.The fundamental difference between a radar level instrument and an ultrasonic level instruments is the type of wave used. Radar level instruments use radio waves instead of sound waves used in ultrasonic instruments. Radio waves are electromagnetic in nature (comprised of alternating electric and magnetic fields), with very high fr...

    The working principle and five precautions for using the radar level sensorThe radar level sensor is a measuring instrument based on the time travel principle. The radar wave runs at the speed of light, and the running time can be converted into a level signal by electronic components. The probe sends out high-frequency pulses and conducts them along the cable and rod probes. When the pulses meet the surface of the material, they are reflected back by the receiver in the meter, and the distance signal is converted into a level signal, Transmit-reflect-receive is the basic working principle of radar level sensor.The antenna of the radar sensor emits electromagnetic wave signals in the form of beams. The emitted waves are reflected on the surface of the material to be measured, and the ...

    The radar level transmitter should be installed to avoid contact between the sensor and the tank wall and should be kept at a certain distance from the tank wall. Because the radar level transmitter is measured by transmitting high-frequency microwave pulses along the detection component, the dielectric constant changes when these pulse waves encounter the measured medium, causing the emission. Therefore, if the installed radar level transmitter is too close to the tank wall, the dielectric constant of the tank wall may be obtained, which directly leads to the in accuracy of the measured parameters.Correct installation method of radar level transmitter:1. Installed one fourth or sixth of diameter.Note:the minimum distance from the tank wall shall be one tenth ...
