H2flow FlowVis FV-2 GPM Flow Meter and Check Valve, 2-inch | FV-2

FV-2 is the GPM-scale FlowVis model for 2-inch pipe, combining a flow meter with check-valve functionality. Its listed flow range is 10–110 GPM. Match the model and pipe schedule on the scale; FV-25, metric-scale, union-body and retrofit versions have separate references.

The manufacturer body drawing shows a 2-inch slip connection and a 2.5-inch interface with a coupling. The manufacturer separately identifies FV-2 for a 2-inch scale and FV-25 for a 2.5-inch scale. Match the model, actual pipe size and pipe schedule rather than relying on the outside fitting alone.

Follow the complete manufacturer guide for flow direction, access to the scale, mounting orientation and chlorine-feeder placement. The manual distinguishes salt generators from tablet or erosion feeders; do not treat all feeder arrangements as interchangeable.

H2flow describes a three-year limited warranty subject to its eligibility, date-of-supply, installation and use conditions. Review the warranty section in the linked manual for the full coverage, exclusions and service procedure.
