Product Details
Flowline EchoPro LR31 Pulse Radar Liquid Level Transmitter
Flowline EchoPro LR31 intrinsically safe 26 GHz pulse radar transmitter provides continuous level measurement up to 20 m with a 4 mA to 20 mA analogue and HART digital signal output. Configurable via a remote push button display module or Flowline WebCal software. 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. The LR31 comes with a 10 m cable, mounting bracket and display module. The sensor is designed for bracket mount installation suspended above the liquid level.
