FRM6100 radio wave velocity meter is a non-contact flow velocity detection device independently developed by our company, which can be used to monitor the surface velocity of water bodies such as natural rivers, open channels, and underground pipe networks and assist water treatment operations.
This radio wave flow meter works in the 24GHz ISM frequency band and adopts the CW mode, which can detect the water flow velocity information in real time around the clock, and is not affected by climate, temperature, water vapor on the water surface and pollutants in the water. The product has a built-in efficient back-end processing algorithm, which can accurately obtain the water flow speed.
