Automated water system (pressure transducer, flow transducer, motorised valves, and pump)

Need to build a control system that is capable controlling an upstream valve/pump based on downstream pressure differential (PID control). The system must also be able to shut off a valve when a predetermined volume of water has passed through the system (some flow sensor will be needed for this). The system ma be built in arduino or something else that is easy to expand/edit without extensive programing experience. The system must be able to store and transmit the data remotely and also have remote control capabilities.
