Flowline LR85-0301 EchoBeam® LR85 Series 80GHz Radar Liquid and Solids Level Sensor with 3" NPT Thread Process Mount and Modbus Signal Output

Item #LR85-0301
  • The threaded mount is typically applied in liquid applications
  • 80 GHz technology provides reliable, maintenance-free operation
  • Measures with significant dust, agitation, foam, or low dielectrics
  • 4° beam is ideal for applications with limited measurement space
  • Rugged PFA antenna provides the highest corrosion resistance
  • IP66/67 enclosure for outdoor installations exposed in all weather
  • LCD push button display for tank level indication and adjustment
  • Measures level height or air gap distance, and tank or silo volume
  • Uses Bluetooth Version 5.0 and has a range of 26.2 ft
  • Configuration via LevelTap™ App, LCD display, HART, or Modbus
  • 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. Flowline's 80 GHz radar technology is unaffected by most media, process, or environmental factors. The LR85 general purpose 80 GHz radar level sensor transmitter provides continuous level measurement up to 196.8' (60m) for solids or 393.7' (120m) for liquids, with a 4-20 mA with HART or Modbus signal output. The threaded mount is typically applied in liquid applications. The gimbal flange is intended for solids applications and allows the antenna to be aimed against the angle of material repose. The gimbal flange includes a 1/4" air purge connector through which dust buildup can be optionally blown off the antenna. 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. The level sensor transmitter measures solids and liquid media with a dielectric constant value greater than or equal to 1.6 such as pellet, grain, powder, or aggregate solids, and water, chemical or petroleum-based liquids.
