Page 3: Description
1. description FlowVis® is a revolutionary, patented solution for accurate and reliable fl ow and velocity rate measurement in fresh water applications such as swimming pools, spas, fountains, water features, irrigation systems, ground water applications, well water and solar systems. A FlowVis® model also exists for Flotation Tanks and where the Fig.1.0: FV-15;... -
Page 4: Concept
2. concept As fl ow increases, the fl apper moves forward toward its fully open position. The fl apper’ s angular position is directly related to the fl ow rate through the valve body / tee / pipe. A calibrated scale on the valve’ s lid provides a highly accurate reading of the fl ow rate and velocity. -

4. service repair kit Service repair kits are available for all models. FV-SK for all 1.5”, 2”, and 2.5” models, comprising: • 1 x o-ring • 1 x spring • 1 x fl apper and indicator arm (for all models except FV-C-S, and FV-C-Saline) •... -
Page 6: Valve Body Feature
5.2 Valve Body Feature On the side of the valve body that is used for the 1.5”, 2”, and 2.5” models, you may notice the feature shown in Fig.1.4. Note that models with valve bodies produced aft er mid-2022 as well as all models with tees and saddle clamps do not possess this feature): This feature has no functionality relating to the operation of the FlowVis and is... -

Page 10: Installation Locations
7. installation locations 7.1 Systems using Salt Generator Cells Due to the fact that Salt Generator Cells have their electrical supply turned off under low or low fl ow conditions, there is virtually no possibility of damage being caused to the FlowVis unit by these devices. Therefore, the primary installation consideration is where will the unit provide the greatest benefi t to the customer. -
Page 11: Systems Using Erosion Chlorine Feeders
7.2 Systems using Erosion Chlorine Feeders (hockey puck-style) Material selections such as corrosion resistant Viton and Hastelloy c-276 ensure that FlowVis will provide many years of trouble-free operation in normally treated, sanitized pool water conditions. However, certain brands and designs of inexpensive Erosion Chlorine feeders are known to fail and release high concentrations of chlorine or even chlorine gas into the surrounding fi ltration system. -
Page 12: Installation
FlowVis® is inadvertently installed into the plumbing in the wrong direction, simply remove the (8) screws holding the lid in place and rotate the entire lid assembly by 180°. IMPORTANT NOTES: For all models 2.5” and smaller, always remove the FlowVis lid assembly prior to gluing in the valve body. When selecting a physical location to install FlowVis, be sure to allow accessibility to read the scale on the lid. Due to the possibility of excessive turbulence, models FV-3, FV-3-L, FV-4, FV-4-L, FV-6, FV-6-L, FV-8 and FV-8-L should not be installed directly after the pump. FlowVis models are designed for the specific pipe Schedule stated at the bottom of the flow scale label. While it is important to comply with the specific Schedule of pipe, the accuracy stated within this manual can be maintained if a short length (3-6 inches / 75-150mm), of the correct pipe Installation H2flow Controls FlowVis®... -

Install the o-ring into the socket on the underside of the upper-half of the Saddle-Clamp. Position the Clamp to the pipe so that the o-ring is centered around the drilled hole. Evenly tighten the nuts and bolts until both halves of the Saddle Clamp are mated together. H2flow Controls FlowVis® Installation... -

The amount of pipe to be removed is shown in Fig.2.0. Fig.2.1 NOTE: The lid assembly from the standard valve body cannot be transferred to a union style valve body (and visa-versa), due to the fl ow reading being diff erent.

Page 18: Tightening Of Lid Screws
Screws should be tightened to a final torque of 25 inch / pounds or 2.8 Nm. IMPORTANT NOTE: Failure to adhere to the above lid assembly installation instructions by tightening the FlowVis lid screws using an impact driver, electric screwdriver, or any other power tool, will almost certainly result in a cracking of the polycarbonate lid assembly. The evidence of such an installation will be clear and obvious and will RENDER THE FLOWVIS WARRANTY NULL AND VOID. Installation H2flow Controls FlowVis®... -
Page 19: Operation
9. operation 9.1 Reading the Flow Rate The FlowVis® is factory-calibrated to be extremely accurate across its full operating range. Any perceived ‘inaccuracy’ is related to the viewing angle at which the scale is being 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. -
