发明名称 MULTI-PROCESS ELECTRONIC CONTROL VALVE SYSTEM
摘要 A valve system is disclosed. The system has a main valve that is adjustable for output flow and pressure. The system also includes an output flow transducer, an output pressure transducer, and a fluid depth transducer. A microcontroller is operatively coupled to the valve, the output flow transducer, the output pressure transducer, and the fluid depth transducer. The microcontroller operates the valve to selectively control the output flow, the output pressure, and the fluid depth according to inputs received from a user.
