FlowVis Flow Meter FV-C-S

FlowVis Flow Meter with Safety Flapper is designed for swimming pools with a SVRS Systems (Safety Vacuum Release System). This flow meter features a non-sealing flapper for these types of applications but will also work great for any other type of installation requiring a flow meter This flow meter does not provide check valve functionality.

The Virginia Graeme Baker Pool and Spa Act requires that all public swimming pools and spas that have a single main drain or multiple drains that are 3 feet or less (center to center) from each other, be fitted with a backup anti-entrapment system. Such systems include, but are not limited to, SVRS and Automatic Pump Shut Off systems. Special consideration must be made when installing a FlowVis to such applications. Several of these systems do not allow the use of Check Valves. It is the responsibility of the installer to make sure that the requirements of the specific backup system in use are maintained.

The FlowVis is a revolutionary, affordable, and highly accurate Flow Meter. As flow increases and decreases, the 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 x 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.

FlowVis Features:
  • For use with 2" or 2 1/2" Pipe
  • Measure flow rates from 10 to 110 GPM
  • Non-Sealing Safety Flapper for Pools and Spas with SVRS Systems.
  • Installation flexibility - far less space required than other flow meters
  • Unique design results in maintained accuracy even with entrained air caused by suction leaks.
  • FlowVis provides a precise, easy-to-read flow rate
  • Maximize energy savings by slowing the pump to its lowest required speed for pool sanitation
  • Allows precise and repeatable valve positioning for perfect water feature operation
  • Design life of 15 years with spring replacement every 7.5 years
  • Clear, easy to read scale
  • No calibration required
  • Accuracy of +/- 2 GPM
  • Rugged construction
  • Pressure tested to >50psi
  • NSF certified
  • 5-year manufacturers breakage warranty
  • Assembled in the USA

The 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 +/- 2 GPM accuracy. Note: Accuracy: of +/- 2 GPM from 0 to 100 GPM verified by NSF testing.
