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 LR81 general purpose or intrinsically safe 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 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 level sensor transmitter for tank, sump, lift station, weir, canal, reservoir, silo, bin, conveyor, transfer station 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 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
- Configuration via LevelTapTM App, HART communicator or Modbus
- Low 9V or 12V operation is ideal for battery powered systems
