Accurate Chemical Feed That Follows Water Usage
The Stenner Proportional Injection System is designed for applications where chemical feed rates need to automatically adjust based on the amount of water being used. Instead of operating at a constant rate, the system injects solution in proportion to water volume, helping maintain consistent treatment even when water demand changes throughout the day.
At the heart of the system is a dry contact water meter, a PCM controller, and a Stenner Classic Series fixed output pump. As water moves through the system, the meter sends signals to the controller, which activates the pump and delivers the proper amount of treatment solution. This provides accurate chemical dosing based on actual water consumption.
One of the biggest advantages of the Proportional Injection System is that it arrives pre-assembled on a heavy-duty panel. Installers do not have to source and mount individual components because the major system elements are already assembled and organized for easier installation. A built-in wiring compartment keeps cords and wiring neatly contained, while union connections simplify future maintenance and service.
The system is especially useful in applications where water demand can vary significantly, such as well water systems, irrigation networks, livestock and poultry operations, and facilities with variable-speed pumps. Because the injection rate follows water usage, the system can provide more consistent treatment compared to fixed-rate dosing methods.
