The intrinsically safe 26 GHz. pulse radar transmitter provides continuous level measurement up to 98.4’ (30m) with a 4-20 mA analog and HART digital signal output, and is configured via its remote push button display module or HART communicator. The non-contact liquid level sensor is intended for industrial wastewater, municipal storm or sewer lift station, reservoir, river, canal or open channel applications located below or above grade. Select this sensor for challenging process conditions that may include light surface foam or agitation, small trash or plant material, wind, condensation or vapor. Each comes with a 32.8’ (10m) cable, mounting bracket and display module. The sensor is designed for bracket mount installation suspended above the liquid
Lift Stations
Industrial and municipal pump lift stations collect and transfer wastewater or stormwater into treatment. These receptacles are dynamic environments that contain dirt, grease, oil, agitation, sludge, foam, condensation, chemicals or vapor. The LR31 pulse radar sensor is unaffected by such challenging process conditions, and is designed for bracket mount installation, either downhole or above grade based on your needs.
