Analysis Of Problems In The Use Of Radar Level Meters.
The radar level meter 4-20ma is a kind of level-measuring instrument with the advantages of high accuracy and wide measuring range. The radar level sensor is suitable for all harsh environments, such as high temperatures, high pressure, and dust. The radar level meters have been widely used in electric power, steel, metallurgy, cement, paper, food, petrochemical, and other industries. In the following, we will show several cases to understand the radar level sensor in the working conditions of the application.
A coal chemical enterprise uses our radar level sensor to measure coke. The measured process temperature is 70℃, and the process pressure is atmospheric. Users reflect that the non contact radar level transmitter in the use of the process of measurement inaccuracy. Our engineers went to the site to check and found that the site has two bins connected. The two bins have a baffle of about two meters, and each bin has a feed port. After the radar level meter 4-20ma was installed, the staff didn't adjust the gimbal angle in time. So, the radar level meter 4-20ma could only measure the direction from the No.1 silo to the silo wall, which led to the inaccurate measurement of the radar level transmitter on site. After adjusting the gimbal angle and setting the parameters of the radar level sensor, the measuring data was accurate.
A chemical company uses our radar level meter 4-20ma to measure lime powder. The customer also reported that the non contact radar level transmitter can't measured. After checking, the engineer found that part of the radar level sensor parameters were set wrongly. Then, the engineer carefully checked each radar level sensor and reset the parameters of the radar level meter 4-20ma to solve the problem.
One of our local cement factories uses our radar level sensor to measure cement powder. The customer reported that the data measured by the non contact radar level transmitter was inaccurate. Our technical team judged that there was interference, which led to the wrong measurement of the radar level transmitter. Our engineers connected an anti-interference module to each radar level meter and set the corresponding range according to the height of the tanks on site.
The radar level transmitters used in these three measurement cases include 26G high-frequency radar level meters and 80G frequency modulation radar level transmitters. Radar level measurement in the medium although different, the overall problem is similar.
