The FlowStat Paddle Wheel Flow Meter with integral sensor provides for very simple installation and operation. The sturdy Stainless Steel body provides durability and a long service life. FlowStat is offered with multiple outputs to choose from in addition to visual indication of flow through its optional clear cover where you can see the Rotor Flow. The straight fluid path and large spinning rotor means there is minimal pressure drop.

Applications include:

  • Chillers & Cooling Systems
  • Solar
