Flow Switches
Copper
PVC
The dry contact flow switch for PVC or copper are both 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 copper has an adapter for soldering to copper pipe. The nominal activation points are based on installation in to an industry standard, smooth 3/4″ or 1″ copper pipe. The activation point for 3/4″ is 1.2 gallons per minute. The activation point for 1″ is 1.9 gallons per minute.
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″ schedule 80 PVC tee. The activation points are 1.2 gallons per minute for 3/4″ and 1.9 gallons per minute for 1″.
