Tokyo Keiki Flat Radar Level Sensor MRF-10

Radar Level Sensor MRF-10

Features :

The Tokyo Keiki Flat Radar Level Sensor  MRF-10 is a loop-powered radar level gauge, which can be installed easily in a variety of applications. The MRF-10 employs a non-contact radar level gauging principle based on pulsed microwave signals and is suitable for level measurement in applications such as liquids, pastes, and slurries.

Tokyo Keiki Flat Radar Level Sensor MRF-10 uses a 5.8GHz low-power pulsed microwave. It provides good measurement stability because the propagation of microwaves is less affected by a change in temperature, pressure, or gas conditions in the tank.

  1. IP68 submergible
    Stormwater will not break MRF-10 under the water.

  2. Compact body (Height: 54mm)
    Height: 54mm, easy installation for narrow spaces like under the Manhole

  3. Loop-Powered
    Easy replacement to existing Loop-powered instrumentations

  4. HART communication
    HART protocol has been superimposed onto the analog output

  5. Easy Configuration
    Graphical PC software by HART

  6. Simple one-piece structure
    No independent main console required
