What is the measurement effect of the 120G FMCW radar level gauge? We use the measurement data to prove. The test lasts for 4 days. The radar level gauge measurement data (echo curve and historical curve) are taken every day. The gauge automatically records the historical curve. Through the analysis and judgment of the echo curve and the historical curve, Make sure the radar level gauge is working properly.

The following is a test report of Xi'an Dechuang 120G FMCW continuous wave radar level gauge DCRD1000B in a chemical plant in Guangzhou:

                                                           120G radar level gauge trial report

Address: Guangzhou XXXXX Chemical Co., Ltd.

Purpose: 120G radar level gauge tested under a lot of foam conditions

Content:

1. Instrument parameters and on-site conditions:

Process connection: DN65/PN10; Medium: Chlorinated paraffin

Temperature: 90 °C ; Pressure: <1MPa

Supply voltage: DC24V ; Output: 4-20mA ; Range: 3m

Site conditions:

The working conditions are complicated, and a large amount of steam and foam are generated during the reaction (the foam thickness is up to 800 mm at the highest), and the liquid level fluctuates greatly.

2. Test process data

  The test lasts for 4 days. Every day, the meter measurement data (echo curve and historical curve) are taken. The meter automatically records the historical curve. Through the analysis and judgment of the echo curve and the historical curve, the instrument is guaranteed to work normally. The following is a 4-day meter. Record data.

Day 1st :

Day 2nd :

Day 3rd :

Day 4th : 

3. Problems

At the beginning of the reactor, a large amount of chlorine gas enters the reactor. At this time, the reaction is intense, and a large amount of foam is generated, which fills the entire reactor. Due to the excessive thickness of the foam (about 800 mm), the echo signal of the meter is weak or There is no echo, which affects the normal measurement of the meter. (Note: This condition is only generated at the beginning of feeding, and will not appear during normal production)

4. Trial results analysis and summary

After four days of on-site test of the instrument, the 120G radar level gauge satisfies the customer's requirements in a large number of foam conditions, solves the problem that many instruments cannot be measured by a large number of foam conditions, and shows that the instrument is in complex conditions. Reliability and stability. At the same time, because the instrument adopts a variety of high-tech technology, the instrument has low installation requirements, quick and easy debugging, and simple maintenance, which has been affirmed by the leadership of the trial company.
