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.

• Combined flow meter and check valve – no calibration required
• Installation flexibility. No plumbing restrictions for precise flow measurement. Install next to elbows, tees, etc. with little or no degradation in performance
• Clear, easy to read scale in GPM or optional LPM with key velocity points (FPS)
• NSF Certified to 50 psi
• Manufactured in the USA. Schedule 40 CPVC
• Available in 3″ and 4″ Schedule 80 PVC versions
