Marsh McBirney Flo-Dar Portable & Fixed Options
The Flo-Dar™ Family of flow meters provide a revolutionary approach to open channel flow monitoring. Flo-Dar™ combines digital doppler radar velocity sensing technology with ultrasonic pulse echo level sensing to remotely measure open channel flows. Perfect Solution for Difficult Flow Conditions:
- Flows with High Solids Content
- High Temperature Flows
- Caustic Flows
- Large Man-Made Channels
- High Velocities
- Shallow Flow
- Personnel have no contact with the flow during installation.
- Maintenance caused by sensor fouling is eliminated.
- No profiling required.
- Field Replaceable/Interchangeable Sensors and Monitors.
Here's How It Works
Flo-Dar™ transmits a digital doppler 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 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.
