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 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 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 solids and liquid media with a dielectric constant value ≥ 1.6, such as pellet, grain, powder or aggregate solids, and water, chemical or petroleum-based liquids. Select this level sensor transmitter for tall dusty silos and bunkers or difficult liquid process applications.
FEATURES
- 80 GHz technology provides reliable, maintenance-free operation
- Measures with significant dust, agitation, foam or low dielectrics
- 4º beam is ideal for applications with limited measurement space
- Rugged PFA antenna provides the highest corrosion resistance
- Offered in thread or gimbal flange mount with optional air purge
- 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
- Configuration via LevelTapTM App, LCD display, HART or Modbus
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.
