Styles Styies Sensitivity 22. Charge and discharge of a reservoir is a common process in industry as well as a need for mixing o or more substances. By using automated valves this process can be completely automated Let's say that the fluid used in the example is water, and that a reservoir has to be filled and ptied only time to make the problem simple Vi S1 92 When you push the start button on the operating panel, valve V1 opens and a reservoir starts filling up with water. At the same time, motor M of the mixer starts working. When the reservoir fills up, water goes up and reaches the level set by a sensor S1. VI valve closes and motor of the mixer stops. Valve V2 opens after a delay time of 10 seconds then, and a reservoir starts emptying. When water level falls below the level set by a sensor S2, valve V2 closes. Lamp L1 indicates motor is working, Lamp L2 indicates a low level, lamp L3 indicates high level.
