The Potter Amseco VSG-2-1/2-76-1 is a flexible vane type of waterflow switch for use in wet pipe water mist systems where a low flow for alarm is required. It is designed for installation in sections of 2-1/2" stainless steel or brass pipe with wall thickness.

The unit may also be used as a sectional waterflow detector on large systems.

The unit contains an output relay and an adjustable electronic retard. The relay is actuated when a flow of 3 gallons per minute (11,4 LPM) or more occurs downstream of the device. The flow condition must exist for a period of time necessary to overcome the selected retard period.
