The EchoBeam LR80 80Ghz radar liquid and solids level sensor transmitter technology is unaffected by most media, industrial or environmental factors and the Flowline intuitive Level Tap App makes configuration simple. The LR80 is a general purpose80GHz radar level sensor transmitter that provides continuous level measurement up to 32.8 ft. (10m) for liquids or 16.4 ft. (5m) for solids with a 4-20 mA signal output. The level sensor transmitter is wirelessly configured over Bluetooth via Flowlines LevelTap® App and enables a worker to see the level, verify the status and manage the setting of connected level sensors transmitters from the safety of the ground or nearby catwalk.

The LR80 level sensor transmitter measures liquid and solids media with a dielectric constant value of 1.6. It measures such media as water, chemical or petroleum based liquids, and pellet, grain, powder or aggregate solids. The EchoBeam is for use in tank, sumo, lift station weir, canal, reservoir, bin, conveyor or transfer station application.
