FV-2 H2Flow FlowVis Flow Meter and Check Valve 2-2.5in.

H2 Flow FlowVis Swimming Pool and Spa Water Flow Meter and Check Valve 2-2.5in. FV-2

One Check Valve is designed for both 2 inch and 2.5 inch pipe.
2 inch pipe slip-fits into valve ports. 2.5 inch pipe is joined using a 2.5 inch pipe coupling, a 45 degree elbow, or a 90 degree elbow. 

FlowVis is the most advanced, affordable, and reliable precision Flow Meter designed specifically for pools, spas, fountains, and water features. But FlowVis is more than just a flow meter; it’s also a fully functioning check valve! Ingenious in concept and flawless in operation, FlowVis is revolutionizing the way pool pumps operate.

FlowVis has undergone exhaustive testing and calibration to ensure long life, accuracy, and repeatability. No other Flow Meter at this price point is NSF certified or comes remotely close to its 97.9% accuracy.* There is no requirement for 10x pipe diameter before or after the unit, meaning FlowVis can be placed directly before or after an elbow or tee fitting with virtually no effect on accuracy.

FlowVis is more than a Flow Meter; it is also a fully functioning Check Valve.

*Accuracy: of 97.9% from 0 to 100 GPM verified by NSF testing. Additional NSF test results available upon request.

Pool installers, owners, and operators finally have a Flow Meter that they can rely on. Accuracy, reliability, and longevity are key among a list of unique features that include:

• Combined functionality of Flow Meter and Check Valve
• NSF certified
• Accuracy of 97.9%
• Installation flexibility-far less space required than other flow meters
• Clear, easy to read scale
• Installs in minutes
• No calibration required
• Unique design results in maintained accuracy even with entrained air caused by suction leaks
• Assembled in the USA
• 5-year breakage manufacturer warranty
• Rugged construction
• Pressure tested to >50psi
• Design life of 15 years with spring replacement every 7.5 years

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. FlowVis allows you to:

1. Maximize the energy-saving potential
2. Achieve efficient skimming
3. Reduce chemical costs
4. Maintain a clean pool
5. Ensure heater efficiency

It is essential to establish the required flow rate in order to achieve turnover requirements. Setting the flow rate too high will use more energy than required and setting it too low will result in a dirty pool.

Save Money. Save Energy.

• FlowVis provides a precise, easy-to-read flow rate
• Knowing the flow enables the pump’s speed to be optimized and energy savings maximized
• Allow precise and repeatable valve positioning for perfect water feature operation
