120GHz FMCW radar level sensor successfully applied to the measurement of liquid chlorine

As a basic chemical raw material, liquid chlorine is widely used in paper-making, textile, pesticide, organic synthesis, metal smelting, chemical raw materials and other industries.

Liquid chlorine, yellow-green oily liquid, toxic. Common storage tanks for storing liquid chlorine are high-pressure steel cylinders, which have the following characteristics:  high sealing performance requirements, high pressure, low temperature, and high measurement accuracy requirements. Therefore, the performance requirements for liquid level measuring instruments are also very high.

DCRD1000B 120Ghz FMCW Radar Level Sensor , the launch angle is 1 °, the measurement accuracy is 1mm, and the blind zone is 10cm. It is especially suitable for the liquid level measurement of low temperature, high pressure and small range storage tanks. Let us take a look at the actual application performance of the radar level gauge DCRD1000B.

Part 1: Instrument apply parameters and work conditions

Production workshop of a chemical enterprise:

Instrument apply parameters： 1)Measuring medium: Liquid chlorine;  2)Measuring Range：800mm;  3)Process connections：Flange DN50 PN40

On-site working conditions:  small measuring range, allowing a small blind area, operated pressure is high, the temperature is low and the minimum temperature is minus 23 ° C.

Part2: Measurement of process level control

 Since DCRD1000B Radar level sensor has been installed, commissioned and put into use for several months, the signal is good and the measurement is accurate.

Part 3: Reliability and Stability of measurement results and analysis

After many project tests, 120G FMCW radar liquid level meter solves the measurement problem of small range, low temperature, high accuracy, shows the reliability and stability of the instrument under complex working conditions, achieving the user's satisfactory measurement effect。
