Specification
Proportional Dosing:
The Select-648 is powered from a single power supply or battery, and has a single input from a water flow sensor or water meter.
Each side of the pump (left and right) operates independently. It is therefore possible, for example, to have one side of the pump set to dose at a ratio of 1:10,000 and the other side to dose at 1:25,000.
