How to Solve the Problem of Guided Wave Radar Level Meter Jumping

The data jumping of the guided wave radar level transmitter is a common problem in the practical applications. This kind of problem are mostly related to improper installation of the guided wave radar level transmitter and interference of the instrument signal. In this article, we share the answer to the above question with you through three actual measurement cases.

One of our customers has a factory that uses our guided wave radar level sensor to measure naphthalene. It is the simplest thick ring of aromatic hydrocarbons, the chemical formula for C10H8, by two benzene rings share two neighboring carbon atoms and thickened, commonly used as dyes, resins, solvents, and other raw materials for production. During use, the guided wave radar level sensors often have jumping problems. Our after-sales engineer went to the site to disassemble the guided wave radar level sensor for inspection and found that there were crystals in all the pipes of the guided wave radar level sensor, causing the guided radar level transmitter signal to be unable to be transmitted. In addition, the impurities at the bottom of the tank were not cleaned, and the probe rod was submerged, causing the signal at the bottom of the tank to be too large, causing the guided wave radar level transmitter to jump. Our after-sales engineers immediately explained the cause of the problem to the customer and proposed the need to regularly clean the nozzles and impurities at the bottom of the tank. After cleaning, the guided radar level transmitter resumed measurement.

A company uses our guided radar level transmitter to measure acetic acid at room temperature. Acetic acid is an organic compound, a one-element organic acid, and is the main component of vinegar. Pure anhydrous acetic acid is a colorless hygroscopic liquid, which becomes a colorless crystal after solidification. Its aqueous solution is weakly acidic and highly corrosive. In the process of measurement, the guided wave radar level transmitter jumped. Our after-sales engineers checked and found that the guided radar level transmitter cable length is 15 meters, while the actual height of the site is 14.5 meters. Due to the measurement in the guided wave tube, the installation base has some tilt, resulting in interference signal, which led to the radar level transmitter jumped. The solution of the after-sales engineer is to add a PTFE bracket to prevent the cable from touching the pipe wall and tie up the long part of the lower end of the cable to prevent it from touching the bottom of the tank.

A ship transportation company uses our guided wave radar level sensor to measure gasoline at room temperature and pressure. In the process of use, some guided radar level transmitters have jumped and can not be measured normally. There is also a dead phenomenon. After the inspection, the after-sales engineer found that there were some problems with the installation of the on-site guided wave radar level sensor. The weight was welded to the short pipe at the bottom of the ship, causing the radar tank bottom signal to be too strong. It is necessary to enlarge the blind area of the guided radar level transmitter and then reduce it with priority to weaken the signal at the bottom of the tank so that the guided radar level sensor can measure liquid inflow normally. Another malfunctioning guided wave radar level transmitter had no response to the display buttons and dead output after a power outage. The radar level sensor returned to normal after replacing the movement.

Although the three cases shared in this article all have the same problem with guided wave radar level sensors, the causes and solutions to the problem are different. It means that you should operate blindly once you have encountered a problem in the measurement. If you can not solve the problem, please promptly contact the engineer for remote or on-site guidance.
