An embedded liquid vessel with submerged pressure sensors tracks soil settlement continuously, reducing manual site visits and sparse readings.
Magnetic shielding blocks motor harmonics in a corrugated tube height measurement system, ensuring stable pressure readings despite external interference.
Liquid-filled hose connects pressure sensors to determine relative height via hydrostatic pressure differences, replacing complex optical leveling systems.
A sensing system uses a float and strain arm to detect structural inclination via optical fiber bending deformation.
A grade-leveling tool uses a transparent hose and reservoir to form a vertical barometer that measures ground elevation differences.
A liquid-filled communicating tube device establishes a stable height reference to detect guide position deviations in coordinate measuring machines.
