How It Works
The Stenner Pump Control Module is a component of the proportional feed system, which delivers repeatable doses regardless of the system’s flow rate. The system is used in applications requiring proportional chemical injection.
The proportional feed system, Stenner refers to as the PCM system consists of three components:
• PCM – pump control module
• Single head fixed output pump (45 or 85 model)
• Dry contact water meter
The water meter equipped with a reed switch sensor and cable sends a pulse signal to the PCM which activates the pump to deliver the desired dose based on water volume. The PCM turns on the pump for the set duration each time a pulse is received. The on time can be adjusted to inject the correct amount of solution into the water line.
There are four models with different on-time duration settings that are factory preset. The PCM’s available time range can be converted to any of the four time ranges available without purchasing another PCM model.

|Time Range||Model Number|
|0.1 – 1.0 Second||PCM1|
|0.5 – 5.0 Seconds||PCM5|
|1.0 – 10.0 Seconds||PCM10|
|2.0 – 20.0 Seconds||PCM20|
