Solution for a Water Tank Level with PLC Ladder Control
|
Water-Tank System Level Controller See control of water level in a reservoir. The entrance to the pressure transducer, Vp, a full tank varies between 0V (empty tank) and 5V (). An output voltage, Vo, a valve will change the situation, the rate of filling tanks. Vo varies between 0V (no water) flow) and 5V (maximum flow. The system will always be: “Emergency is electrically connected. The desired height of the container is indicated by a different voltage, VD. The output voltage is measured by Vo = 0.5 (VD - Vp). When the output voltage is greater than 5 V be 5V, and below 0V 0V. (more…)
