PCM - Pump Control Module
How It Works
The 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
• PCM – pump control module
• Single head fixed output pump (45 or 85 model)
• Dry contact water meter
The water meter 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 determined to inject the 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.
