Flowline LR83-0301 EchoBeam® LR83 Series 80GHz Radar Liquid and Solids Level Sensor with 1-1/2" NPT Process Mount and Modbus Signal Output

Item #LR83-0301
  • 80 GHz technology provides reliable, maintenance-free operation
  • Measures level height, air gap, tank volume or open channel flow
  • Rugged PVDF antenna and PBT-FR enclosure for corrosive media
  • IP66/67 enclosure for outdoor installations exposed in all weather
  • LCD push button display for level or flow indication and adjustment
  • 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, LCD display, HART, 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 LR83 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 or Modbus 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 sensor for tank, sump, weir, canal, reservoir, silo, bin, conveyor or stockpile applications.
