The automation of dosing and control of chemical products is a step forward from manual processes and is not incompatible with other treatments. With a Free Chlorine sensor or ORP and a pH electrode, concentration levels of the pool can be determined. These measures are analyzed by a controller, the user must first get optimal set points of Free Chlorine and pH.
A diaphragm pump (also known as a Membrane pump) is a positive displacement pump that uses a combination of the reciprocating action of a rubber, thermoplastic or teflon diaphragm (membrane) and suitable valves on either side of the diaphragm (check valve, butterfly valves, flap valves, or any other form of shut-off valves) to pump a fluid.
