The Model VSR is a vane type waterflow switch with non-corrosive insert for use on wet sprinkler systems. It is UL Listed and FM Approved for use on steel pipe.

The VSR may also be used as a sectional waterflow detector on large systems. The VSR contains two single pole, double throw, snap action switches and an adjustable, instantly recycling pneumatic retard. The switches are actuated when a flow of 10 GPM (38 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.
