hi every one , i am doing my FYP and I use plc to control
i have many problems
let me explain the project
water tank with ultrasonic, as the water decrease in the tank the water flow out should decreases too (I'll use flow control valve to do that)
I want to show the info. on LCD screen (water flow rate, the water level on the tank, is the water increase or decrease?)
the problems are
1) how to make the PLC know if the water level increase or decreases?
2) how to show the info. on LCD ?
3) how to send the wanted output signal to the valve?
If you know any references please send it to me
thanks
