will this circuit work as intented?

[ahmed_eshra]

My question is will the following circuit work as an automatic pump control.
sorry for the terrible design.
if i connect the analogue pressure sensor in the primary connection in the circuit after a motorized pump,and the secondary sensor before the pump, and the motor leads between the motor and the mains ,will the following happen?

---------------------------------------------
1-if the difference between the pressure at each side of the pump is lower than a pre-set value by pot 1(which means someone opened the tab), then the relay should close the circuit ,leading to the pump being run.
2-if the difference between the pressure at each side of the pump is higher than a pre-set value by pot 0(which means someone closed the tab), then the relay should open the circuit ,leading to the pump shutting off.

please don't flame me for a major design and just point it out.
if it would work can someone help me make a breaboard design with recommendations for parts to be used.
i need to measure the difference between pressures as sometimes the water increases it's pressure or decreases it.
also thanks in advance and sorry for improper formatting and language,still new to the forum.
