Flo-Dar combines advanced radar velocity sensing technology with ultrasonic pulse echo level sensing to remotely measure open channel flows. High Velocities Shallow Flows Benefits Personnel have no contact with the flow during installation. Here's How It Works Flo-Dar transmits a beam that interacts with the fluid and reflects back signals at a different frequency than that which was transmitted. These reflected signals are compared with the transmitted frequency. The resulting frequency shift provides an accurate measure of the velocity and the direction of the flow.
Level is detected by ultrasonic pulse echo.
Accurate Flow Measurements Flo-Dar provides the user with highly accurate flow measurements under a wide range of flows and site conditions. By measuring the velocity of the fluid from above, Flo-Dar eliminates accuracy problems inherent with submerged sensors including sensor disturbances, high solids content and distribution of reflectors.
