PLC Process
• The apparatus has two transparent tanks, mounted one above the other.
• A float switch in the reservoir monitors the level of water.
• An in-line flow sensor provides a pulsed output.
• A variable-speed pump transfers water from the reservoir into the upper tank.
• The water can drain down to the lower tank and then back into the reservoir.
• Solenoid valves may be individually opened or closed to control and redirect the movement of the water.
• The pump control is on or off, but a manual control allows the user to set the speed.
• Each tank includes two level sensors which measure maximum and minimum water levels.
• Its frequency is proportional to the flow rate and the number of pulses proportional to volume.
