Swimming Pool FlowVis Valve

Detailed Description

Swimming Pool FlowVis Valve

The FlowVis is a revolutionary, affordable, and highly accurate Flow Meter. A flow meter is essential for any pool that uses a variable speed pump. It’s the only way to know the pool water is being turned over at least once/day and still take advantage of the huge savings in electricity by slowing down the pump.

The best part is that the FlowVis is more than a Flow Meter; it is also a fully functioning Check Valve. As flow increases and decreases, the Check Valve's flapper swings within its range of motion. A specifically designed calibration spring, indicating arm, and an extended height valve body lid constitute the fundamentals of the FlowVis design concept.

The FlowVis is a revolution in reliable flow measurement. It is the most advanced, affordable, and reliable precision Flow Meter designed specifically for pools, spas, fountains, and water features.

FlowVis is built to last. It's robust, yet unobtrusive design means that unlike competing Flow Meters, FlowVis won't get kicked, tripped over, or broken. Unlike Pitot tube / Rotameter style devices, FlowVis will not stick, bounce, or provide inaccurate readings of flow. There are no saddle clamps to corrode, flat rubber seals to deteriorate, or small holes to become blocked.

A factor that plagues the installation of flow meters is the manufacturers' stated need to have a significant length of straight pipe available. Most often this is 15 times the pipe diameter. So, for a 2.5" diameter pipe, this would require 37.5" of straight pipe; anything less will induce even greater inaccuracy. FlowVis has no such restrictions; you can install it directly between two 90 degree elbows and maintain the same amazing accuracy!

Unlike other Flow Meters, the position in which FlowVis is installed (horizontal, vertical or relative to elbows and tees), has zero effect on its accuracy.
