A chemical plant, measuring sodium silicate of iron dioxide, hydrogen fluoride, process temperature room temperature, process pressure normal pressure, using their radar level meter, model RD-901, RD-902T, RD-906. use process found that the reactor feeding process level stuck value, jump full range, storage tank area there is a feeding will jump change.
After the engineer’s inspection, he found that there were two layers of grate in the reactor, which greatly affected the radar signal, and the feeding port was too close to the radar level meter, and the liquid level splash caused no signal from the radar level meter when feeding, and the problem occurred, and it would return to normal when the feeding was stopped, and the solution was to remove the grate in the tank.
The reason for the jump in the tank is that when feeding, sometimes the liquid level temperature did not drop, the site personnel began to play material, the steam is very large, and the liquid level appears a lot of foam, resulting in the radar no signal, the engineer and the site staff to communicate attention to the operation, the above problems are all solved.
