Design and Testing of a Remote Control-Based Integrated Flow Regulation and Measurement Device

In order to maintain sustainable agriculture, the flow in irrigation systems needs be managed remotely and finely achieve efficient use of water resources. This research develops a measuring device that integrates measurement control precise regulation under remote control. The chooses angular regulating valve as actuation component flow. By experimental study body working characteristics, this paper (1) establishes relationships among pressure front valve, opening pipeline flow; (2) relationship between degree number driving pulses stepper motor, (3) designs decision software. experiment shows coefficient is 84.61, there no leakage loss when closed. It also curve matches law fast-opening features. established correlation performance parameters measured value are both greater than 0.99, indicating decent fitness. test where pressures were 0.10, 0.20, 0.30 MPa, average duration was 62.48 s, with maximum overshoot 5%, steady-state error 6%. showed higher is, better effect is. varied below 3%. With its simple structure, fast time, high accuracy, meets requirements management systems. can used variety rate monitoring scenarios.
