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.

Product installation
ملاحظة:
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
