Tokyo Keiki MRF-10 Radar Level Sensor

MRF-10 radar level meter is a level sensor with HART protocol and current loop power supply. The measuring principle is based on radar technology, measuring the transit time of the signal reflected from the measured medium. The TOKYO KEIKI MRF-10 radar level meter is a loop powered liquid level gauge.

The MRF-10 radar level sensor is installed at the top of tanks or channels. It emits short microwave pulses to the level of liquid. As such pulses are reflected from level of liquid, they are received by the antenna and processed. The time between the emission and reception of the signal is then converted into the value of level of liquid.The MRF-10 radar level sensor is installed at the top of tanks or channels. It emits short microwave pulses to the level of liquid.

Feature

  1. IP68 submergible : Stormwater will not break MRF-10 by under the water.
  2. Compact body (Height : 54mm) : Height : 54mm, easy installation for narrow space like under the Manhole
  3. Loop-Powered : Easy replacement to existing Loop-powered instrumentations
  4. HART communication : HART protocol has been superimposed onto analog output.
  5. Easy Configuration : Graphical PC software by HART
  6. Simple one-piece structure : No independent main console required
  7. Remote Setuputures
  8. IP68 submergible

Typical Application

  • Sewage Drainage Tunnel
  • Water Works Pit Ceiling
  • Vapor-Rich Tank Top Roof
