ELECTRONIC PRESSURE RELAY. REVIEW OPTIMA RS-59 with flow relay function
We continue to discuss electronic systems for automatic pump control. In this video, we will discuss an electronic pressure controller, which also has an additional function, namely: the ability to start and stop the pump in two modes. The first mode: starting and stopping the pump at a given pressure (analogous to a conventional mechanical pressure relay). The second: turning on the pump at a given pressure, switching off at flow.
