Radar Level Sensors

Continuous level measurement in liquids and solids with non-contact radar level sensor

Radar level sensors are ideal for continuous level measurement of liquids and solids in challenging environments that have vapour, gases, temperature variations, extreme temperatures, extreme dust, wind, foam, ice or acoustic noise. ABM’s non-contact radar sensors are plug-and-play, maintenance-free and backed with full customer support to ensure long-term successful operation in the field.

Radar Working Principle

An electromagnetic pulse is transmitted from the sensor. The pulse travels to the surface being monitored and is reflected off the surface back to the sensor. The time-of-flight is divided by 2 and converted to an output signal directly proportional to the material level.

ABM’s non-contact pulse radars have feedback with the environment and automatically adjusts the transmit power, length of pulse and receiver sensitivity to match the current conditions. The same amplitude of echo is received regardless of distance. With self-adjusting technology, the receiver detects only one echo from the measured media while all false echoes are pushed under the noise level and eliminated. In addition, the sensors have a very narrow radiation beam and very short blanking.

Benefits

  • Accurate and reliable measurements with self-adjusting technology – one echo only. False echoes from ladders, partitions, cross-beams, pipes, or material build-up are eliminated. No mounting influence on the sensors performance
  • Maintenance-free due to build-up resistant Teflon antenna and non-contact operation. Water condensation does not affect operation
  • Works on liquid and solid materials, in extremely high temperature processes, sanitary processes, hazardous environments and more
  • Short transmitted pulses, very high resolution to detect oil-water interface
  • Optional remote monitoring and full remote sensor control for set up, calibration, diagnostic and troubleshooting using cellular network
  • Plug-and-play installation with simple push-button calibration
  • Fastest response on the market
