The PCM is a time adjustable controller to actuate Stenner's fixed flow rate metering pump.

The PCM is a time adjustable controller that powers a fixed output pump. It operates with a pulsing dry contact water meter that sends a signal to the PCM which actuates the pump to deliver the desired dose based upon water volume. It is one of the components in the Proportional Injection System that also includes the Classic series single head fixed output pump and a 3/4" plastic water meter pre-installed on a heavy duty panel. Purchasing the items separately offers flexibility with the water meter selection; available in plastic or stainless steel with variety of sizes and pulse rates, to customize your own proportional feed installation.
