Potter VSR-SG is a vane type waterflow alarm switch with retard and a glue-in union, made for CPVC pipe from 1 to 2 inch sizes. It is used on wet sprinkler systems that use CPVC plastic fittings.
The switch signals when flow of 10 GPM (38 LPM) or more occurs downstream and continues for the selected retard period. The union makes installation possible in confined spaces. The cover is held by two tamper-resistant screws that need a special key, and a field-installable cover tamper switch is available as an option.
