Product Detail

Microwave Type Flow Sensor KFD-1


Even one pellet is not overlooked!
High sensitivity and stability with 24 GHz power!

  • Even one pellet is not overlooked by our proprietary circuit.
  • It can permeate substances such as a glass and synthetic resin to enable indirect detection.
  • It is not easily affected by dirt and scale on the detected surface.
  • Both a minute flow and large amount of flow can be detected by adjusting the sensitivity.
  • Powder
  • Granules

Operating Principles

When a microwave emitted from the sensor touches the powders or granules flowing in the pipe, the reflected wave converts and amplifies the frequency drift according to the Doppler effect, and produces contact output.
