The LR81 general purpose 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, Modbus or SDI-12 signal output. The level sensor transmitter is wirelessly configured over Bluetooth via our LevelTap 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 level sensor transmitter for tank, sump, lift station, weir, canal, reservoir, bin, conveyor or transfer station applications.

  • Continuous level measurement up to 98.4’ (30m) with 4-20mA HART, Modbus or SDI-12 outputs
  • Fast and easy setup via Flowline’s bluetooth smartphone app LevelTap
  • Complies with FCC(USA), ISED(CAN) and CE RED (EUR) regulations needed for lawful operation of 80GHz radars in North America and Europe
  • PVDF antenna and PVDF enclosure needed for corrosive liquid applications with IP68 rating in case of submersion
  • Superior accuracy and reliability over ultrasonic level transmitters and unaffected by changes in temperature, foam or dust buildup
