Portable and Permanent Models Now AvailableFlo-Dar Back Lit Graphic WEFTEC 99.jpg (150425 bytes)


Two types of sensor mounts available:
Temporary Mount (no fastening hardware or structure modification -  tension type device).  Permanent Mount (fastens to structure wall)


The Flo-Dar Flowmeter provides a revolutionary approach to open channel flow monitoring. Flo-Dar combines advanced 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 Flows

Benefits

‧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

Heres 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. 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.


Flo-Dar Model 460/Model 450  Radar Based Velocity/Area Flowmeters  
Introducing Flo-Dar™...The perfect solution for your difficult flow monitoring problems. Flo-Dar™ uses non-contact Radar Technology to allow you to measure flow from above the fluid. Flo-Dar™ provides the user with highly accurate flow measurements under a wide range of flows and site conditions.
