AI Technical Summary
Existing level gauges are prone to rapid rises and falls of the buoyancy magnetic plate under dynamic disturbances, leading to unstable readings.
It adopts an inner and outer cylindrical structure, sets up a magnetic coupling transmission between a magnetic slider and a buoyancy magnetic plate, and adjusts the air flow through a connecting component. Combined with a wave-damping cylinder and mesh design, it reduces the interference of liquid surface fluctuations on the buoyancy magnetic plate and delays air pressure changes.
It achieves non-contact synchronous display of liquid level, improves the stability and accuracy of readings, avoids the oil leakage risk of traditional structures, and enhances the stability of float display.
