A chemical plant, measuring phenol, and toluene, using our two radar level meters, a guide wave radar level meter, and another high frequency radar level meter, model RD-701 RD-902. phenol process temperature room temperature, toluene process temperature 130 degrees, process pressure normal pressure.
During use, it was found that the radar level meter would restart in winter when it was below -20 degrees. After inspection, the after-sales engineer decided to replace the ST circuit board, and the restart phenomenon did not occur again after the replacement.
