This is a Stenner Flow Switch for 1 inch PVC Pipe. This dry contact flow switch is two wire, paddle style with glass fiber reinforced plastic construction. The flow switch is designed with a magnetic force to reset the paddle so spring fatigue is eliminated. The Stenner S10P, Econ FP and S Series metering pumps have a flow switch operating mode that can interface with a two wire flow switch that accepts a dry contact signal.
The flow switch for PVC includes a glue-in adapter for easy mounting to a standard PVC slip fit tee. The nominal activation points are based on installation into a Spears 3/4 or 1 inch schedule 80 PVC tee. The activation points are 1.2 gallons per minute for 3/4 inch and 1.9 gallons per minute for 1 inch.
