Flowline LR81-0101 EchoBeam® LR81 Series 80GHz Radar Liquid and Solids Level Sensor with Horizontal Cable, 1-1/2" NPT Process Mount and Modbus Signal Output

Item #LR81-0101
  • 80 GHz technology provides reliable, maintenance-free operation
  • Measures level height, air gap, tank volume or open channel flow
  • Rugged PVDF antenna and enclosure for corrosive liquid or solids
  • IP68 rated sensor for harsh outdoor or below grade installations
  • Sealed 10m PVC jacketed cable for corrosive level environments
  • Zero dead band maximizes the potential fill capacity of small tanks
  • Optionally measures through top wall of plastic or fiberglass tanks
  • Uses Bluetooth Version 5.0 and has a range of 26.2 ft
  • Configuration via LevelTap™ App, HART communicator, or Modbus
  • Low 9 volt or 12 volt operation is ideal for battery powered systems
  • Has an accuracy of +/- 10mm for 0m to 0.39m, and +/- 2mm for 0.4m to 30m.
EchoBeam® is the most reliable and easy to use non-contact level sensor transmitter. The LR81 Series general purpose 80 GHz radar level sensor transmitter provides continuous level measurement up to 98.4' for liquids or 49.2’ 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 greater than or equal to 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, silo, bin, conveyor, transfer station or stockpile applications.
