TThe Flo-Dar Flowmeter provides a revolutionary approach to openchannel flow monitoring. Flo-Dar combines advanced Digital Doppler

Radar velocity sensing technology with ultrasonic pulse echo level

sensing to remotely measure open channel flow.

Here's How It Works

Flo-Dar transmits a radar 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. Flow is

then calculated based on the Continuity Equation Q = V x A, Where Q = Flow,

V = Average Velocity and A = Area.

Accurate Flow Measurement

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.
