Problem in Fluid Valve.

Hi, first of all i would like to thank anyone who can help me in my problem in advance.😀

My Problem is that I want to make a prototype that will automatically "refill" the water in the tank. When the tank is completely empty.

Please refer to my diagram so that you will not be confused.

[​IMG]Here are the scenario.

The Fluid Valve A will not open unless the Fluid Valve B is closed. And the water inside the Fluid Tank is completely empty. And will close when the Water Level Sensor is triggered.

The Fluid Valve B is operated by a push button switch. That has a 20 seconds duration before it closes. And it should not work if the Fluid Valve A is open.

What are the types of material will a use? (Valves, Timers, Switches, PCB circuit)

my email address is
I'm a senior Electronics and Communication Engineering Student.
Thanks a lot in advance.
