The EchoBeam LR85 general purpose 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 LR85 is a general purpose 80GHz radar level sensor transmitter that provides continuous level measurement up to 196.8 ft. (60m) for liquids or 393.7 ft. (120m) for solids with a 4-20mA with HART signal output. The level sensor transmitter is wirelessly configured over Bluetooth via the Flowline 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 level sensor transmitter measures liquid and solids media with a dielectric constant value of 1.6.

The LR85 measures such media as water, chemical or petroleum based liquids, and pellet, grain, powder or aggregate solids. The EchoBeam is for use in tank, sump, weir, canal, reservoir, bin, conveyor or stockpile applications.
