EchoBeam® is the most reliable and easy-to-use non-contact level sensor transmitter. Flowline’s 80-GHz radar technology is unaffected by most media, process or environmental factors, and their intuitive LevelTapTM App makes configuration simple.
The LR83 general purpose or intrinsically safe 80-GHz radar level sensor transmitter provides continuous level measurement up to 98.4’ (30m) for liquids or 49.2’ (15m) for solids, with a 4-20 mA with HART or Modbus signal output. The level sensor transmitter is wirelessly configured over Bluetooth via their LevelTapTM App which enables you to see the level, verify the status, and manage the settings of connected level sensor transmitters from the safety of the ground or nearby catwalk. The level sensor transmitter measures liquid and solids media with a dielectric constant value ≥ 1.6, such as water, chemical or petroleum-based liquids, and pellet, grain, powder or aggregate solids. Select this sensor for tank, sump, weir, canal, reservoir, silo, bin, conveyor or stockpile applications.
