PERFORMANCE

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 our intuitive LevelTapTM App makes configuration simple.

APPLICATION

The LR83 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 or Modbus signal output. The level sensor transmitter is wirelessly configured over Bluetooth via our 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.

FEATURES

  • 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
  • Configuration via LevelTapTM App, LCD display, HART or Modbus
  • Low 9V or 12V operation is ideal for battery powered systems

CONFIGURATION

Download the free LevelTapTM App at the Apple Store, Google Play or Baidu Store, register and go to Demo Sensors. There you can view the level status and step-by-step or advanced configuration examples prior to sensor purchase.
