Paddlewheel Flow Sensor


The Series IPFS Insertion Paddlewheel Flow Sensor is a Paddlewheel Flow Sensor available for pipe sizes ranging from 3’’ to 40’’ and available in brass, PVC or stainless steel. The Series IPFS has an available hot tap model with a bronze or stainless steel valve assembly. The bearings are made from ruby jewel to reduce the coefficient of friction and maintain high accuracy. The Series IPFS comes with a variety of saddle fittings that come in iron or brass. The Series IPFS is good for large pipe and clean water applications. It is ideal for chemical proportioning applications or any applications with rapidly changing fluid conductivity. The IPFS uses the rotation of an impeller to measure flow. Liquid flow pushes the rotor and the rotation is detected by a Hall-effect sensor. The output is a current sinking pulse signal which can be connected to the Series RTI to display flow rate and total or the Series BAT for a 4 to 20 mA signal conversion.             

The Series IPFS is compatible with clean liquids and suitable for applications such as cooling water monitoring, aquariums, and waterparks. This meter is highly suitable for chemical proportioning or applications with rapidly changing liquid conductivity.
