Simple to install with time-honored reliable perfomance,LWV-B Paddlewheel Flow Sensors are highly repeatable,rugged sensors that offer exceptional value with little or nomaintenance, The output signal of the Model LwV-B is asinusoidal frequency capable of driving a self-poweredflowmeter . The wide dynamic fow range of 0,3 to 10 m/sallows the sensor to measure liquid flow rates in full pipesand can be used in low pressure systems.

The Model LwV-B sensors are offered in a wide range of pipesizes .Sensors can be installed in up to DN65 pipes usingcomprehensive line of custom fittings.
When the power is turned on, the green LED lights up and flashesproportionally to the paddle wheel rotation frequency. The lightingup of the red indicator LED indicates a malfunction of the device.When liquid flows into the pipe, the paddle wheel is rotated. Thenon-wetted permanent magnets inserted in the paddle wheelgenerate a measuring signal whose frequency is proportional tothe flow velocity

Product installation
Note:
The device is not designed for gas and steam flow measurement.
Minimum straight upstream and downstream distances must be observed.According to the pipe's design,necessary distances can be bigger or use a flow conditioner to obtain the best accuracy
