Pump-less systems are pre-fabricated and tested in an easy-to-use wall mount system
The controller allows for a user friendly set up where the system water is routed through a highly reliable mechanical flow switch to assure chemical feed is limited to periods of sampling and flow. The water then enters a see through flow cell which houses the sensor and a convenient sample tap. The micro-controller based unit accepts one probe input, either pH or ORP and, in turn, controls the onboard chemical feed pump. Treatment chemical is fed on-board to the discharge of the flow cell where it returns to the recirculating water. All this is done in a small space.
Two different systems are preconfigured and built depending on your application - pH or ORP.
Any brand of metering pump can be selected to work with these systems.
