® , from H2flow Controls, Inc., of Sylvania, Ohio, is actually three products in one: flow meter, check valve and velocity meter (FV-3, FV-4, FV-6 and FV-8 non-check valve). With more NSF 50 certified models than any other brand of flow meter, it is a favored choice of pool and spa professionals.
Patented and manufactured in the USA, FlowVis has anaverageaccuracyof97.9%(FV-C)98.15%(FV-3)and 98.7% (FV-4), making it the most accurate and reliable flow meter available for pools, spas and water features.
With no calibration required and no need to consider orientation or excessive straight-pipe runs, installation is quick and easy. FlowVis installs horizontally, vertically or even upside-down, and can even be installed next to other plumbing fittings such as elbows with no effect on accuracy.
FlowVis is available for 1.5-, 2.0-, 2.5-, 3-, 4-, 6- and 8-inch inch pipe configurations with additional models designed specifically for retrofit, safety, saline, and metric pipe applications.
An easy-to-read scale in GPM or optional LPM or M3/h, which features key velocity points, makes it possible to view the actual flow rate clearly.
While installing a variable speed pump for energy savings makes sense, the only way to know how to set the pump’s speed is by knowing the flow rate. FlowVis makes it possible to maximize energy-saving potential, achieve efficient skimming, reduce chemical costs, maintain a clean pool, ensure heater efficiency and achieve precise and repeatable valve positioning for water feature operation.
