AI Technical Summary
Existing multi-level sensors cannot be adjusted according to different detection environments, resulting in poor adaptability.
Design a liquid level controller by connecting liquid level regulating pipes between multiple hollow connecting pipes, and setting an upward pressure detection mechanism and pressure sensor on the baffle. The liquid level is detected by the up and down movement of the float, and adaptive adjustment is performed through a data processing module.
It enables flexible adjustment according to different detection needs, improves the adaptability and accuracy of liquid level detection, and has good sealing and connection strength.
