The PRLM-200M radar level sensor is a radar product using the principle of frequency modulated continuous wave (FMCW), which can be widely used to measure the distance, material height, volume, weight and open channel flow of liquids, slurries and viscous, and can also be used to measure solid media such as powders, granules and blocks. It measures reliably even in dusty, agitated applications.
