KnowtheFlow™

Installing a variable speed pump for energy savings makes complete sense, but the only way to know how to set the pump's speed is by knowing the flow rate. There are many advantages to installing a FlowVis® to your pool's variable speed pump.

Variable speed and fixed speed

Regardless of whether a pool pump uses a variable speed or fixed speed, knowing the flow rate is essential.

When installed to a variable speed pump application, FlowVis® will among other things, allow you to maximize the energy-saving potential, achieve efficient skimming, and reduce chemical costs.

When installed to a fixed speed application, FlowVis® will help users determine whether a variable speed pump could help them save energy and thereby justify the investment.
