The FLO-DAR AV Sensor provides an ideal solution for non-contact, maintenance-free portable or permanent sewer flow monitoring.

The FLO-DAR AV Sensor provides a revolutionary approach to open channel flow monitoring. It combines advanced Digital Doppler Radar velocity sensing technology with ultrasonic pulse echo depth sensing to remotely measure open channel flow. Use with the Hach FL900 Series Flow Loggers (wireless or standard) for portable monitoring. For permanent power application sites the FLO-DAR can be connected to the FL1500 Series Flow Monitor. Intrinsically safe models are available.

Intrinsically safe model equipped with optional Surcharge Velocity Sensor (SVS)
During surcharge events FLO-DAR’s SVS electromagnetic sensor will continue to provide uninterrupted and accurate flow monitoring through dry and wet weather flows without the need for routine sensor cleaning or maintenance.

Benefits

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.

Non-Contact Sensor Eliminates Lost Data

No lost data with non-contact, above the flow sensor that is unaffected by fouling due to debris and grease.

Easy Installation and Maintenance

As the sensor is mounted above the flow, personnel have little or no contact with the flow during installation. Future sensor removal and replacement can be done without the need for confined space entry.

Independent Accuracy / Long-Term Stability Verification

FLO-DAR sensor accuracy and long-term stability (up to 3 years without need for site calibration) from low flow depths up to surcharge conditions has been independently verified many times over the years including a formal evaluation by the Alden Research Laboratory, Inc. and recent field evaluations done by municipalities and consulting engineering firms.

Perfect Solution for Difficult Flow Conditions

Operates in the most difficult conditions including flows with high solids content, high temperature, shallow and caustic flows, large man-made channels, and high velocities up to 20 ft/s.

Optional Surcharge Velocity Sensor (SVS)

During surcharge events FLO-DAR’s optional SVS electromagnetic sensor will continue to provide uninterrupted and accurate flow monitoring through dry and wet weather flows without the need for routine sensor cleaning or maintenance.
