Pressure compensation systems, liquid supply systems and methods using the same

A pressure compensated water supply system comprising:

• an automatic control valve (ACV) comprising an inlet and an outlet, the inlet fluidly coupled to a water supply;
• a valve system comprising an inlet fluidly coupled to the outlet of the ACV and an outlet fluidly coupled to at least one outlet in a destination;
• a first pressure sensor configured to detect a fluid pressure (P3) corresponding to an outlet fluid pressure the valve system, the first pressure sensor further configured to produce a first sensor signal indicative of P3;
• a controller configured to communicatively couple to the first pressure sensor;
• and
• an actuator for the ACV, the actuator configured to communicatively couple to the controller and to control a position of a valve within the ACV;
• wherein:
• the controller is configured to determine P3 based at least in part on the first sensor signal and to compare P3 to a target outlet pressure T of said water supply system;
• and
• when P3 differs from T, the controller is configured to produce and send a control signal to the actuator, the control signal configured to cause the actuator to change a position of the valve within the ACV such that P3 at least substantially equals T.

A method of pressure compensation for a water supply system comprising an automatic control valve (ACV) comprising an inlet fluidly coupled to a water supply and an outlet fluidly coupled to a valve system, the method comprising:

• with a first pressure sensor, detecting a fluid pressure P3 corresponding to an outlet fluid pressure of the valve system and producing a first sensor signal indicative of P3;
• and
• with a controller communicatively coupled to the first pressure sensor and communicatively coupled to an actuator for a valve within the ACV;
• determining P3 based at least in part on the first sensor signal;
• comparing P3 to a target outlet fluid pressure T of said water supply system;
• and
• when P3 differs from T, producing and sending a control signal to said actuator, the control signal configured to cause the actuator to change a position of the valve within the ACV such that P3 at least substantially equals T.
