VS 100 velocity sensor connected to a Open Channel Meter (OCM III) or SITRANS LUC500 measures flow rate and volume in a channel with no flume or weir. The velocity sensor, secured to the bottom of the channel, uses the Doppler effect to measure average water speed. It transmits the information to the VS 100 electronics to be processed and sent to the OCM III or LUC500 as a velocity signal.

Using the level measurement and velocity data, the OCM III or LUC500 computes the flow through the channel which can be totalized and logged. This velocity sensor can also be used in a pipe using a screw jack mounting ring that holds the sensor securely in place.

The VS 100 can also be used as a stand-alone velocity sensor providing open channel velocity to a variety of SCADA systems via its analog output.
