Product Overview
The H2flow FV-C-S FlowVis Flowmeter provides a simple way to monitor actual water flow through a pool or spa circulation system. The mechanical flowmeter displays the system flow rate in GPM, allowing operators to verify circulation and monitor changes in system performance.

The unit combines flow measurement with a safety flapper/check valve, eliminating the need for a separate check valve in compatible installations. The FlowVis can be installed in horizontal, vertical, or upside-down orientations and operates without electrical power.
