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. Range: 20-110 Gpm. FlowVis® does not require specific straight pipe lengths before or after its point of installation.
The FlowVis is the ideal valve to install in conjunction with a variable/multi speed pumps. This will enable accurate pump operating speed adjustments to ensure sufficient water flows to the pools filtration and sanitising equipment.
The patent pending FlowVis® from H²flow is a revolutionary, affordable, and highly accurate flow meter that guarantees you will Know the Flow.
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.
FlowVis® is the first flow meter to be tested and certified to NSF 50. The process confirmed
average accuracy was within just 2.01%* between 76 and 416 LPM across all certified models. A significant premium would normally be paid for this level of precision; however, FlowVis® costs far less than other flow meters that come even close to this level of performance.

Installation of the FlowVis® should be in accordance with the following instructions. Normal plumbing procedures such as cleaning, priming and gluing of fixtures should be followed in order to avoid leaks. Unlike other flow meters, FlowVis® is not effected by flow stream disturbances caused by its proximity to pumps, elbows, tees, valves etc. FlowVis® does not require specific straight pipe lengths before or after its point of installation and can be installed close to, or even adjacent to other plumbing fittings. FlowVis® can be installed either horizontally
The FlowVis® is factory-calibrated to be extremely accurate across its full operating range. Any ‘inaccuracy’ is related to the angle in which the scale is read. To avoid so-called ‘parallax error’, it is important to position your eye so that you are looking squarely at the tip of the indicator arm. To achieve this, simply move your head so that you just lose sight of the vertical leading edge of the red arm.
