HDs102 tilt vibration pressure differential static level, also known as tilt vibration pressure differential three in one static level, tilt vibration pressure differential integrated static level, is a high-precision liquid level measuring instrument used to measure the relative settlement, tilt, and vibration conditions of various measuring points in foundations and buildings. The entire level consists of components such as a reservoir, level, protective cover, connecting gas pipe, liquid pipe, and data acquisition instrument.

Mainly used for measuring uneven settlement of various measuring points in large buildings, high-rise buildings, dams, hydropower stations, nuclear power plants, water conservancy hub projects, railways, subways, high-speed railways, comprehensive pipe galleries, etc.

【 Working Principle 】

Differential pressure typeA static level is a precision instrument based on the principle of connectivity, which measures the relative changes in the liquid level height of several interconnected storage tanks installed at the measured point and the liquid level height of the measuring base point (fixed point) tank, and infers the relative settlement change of each storage tank installation position.

【 Application Fields 】

• Monitoring of settlement of rail transit subgradeMonitoring of settlement of subway support walls

• Detection of settlement of mountain and building on the upper part of the tunnel, highway subgrade and slope

• Bridge pier and foundation pit settlement detection The foundation of dams, water conservancy hubs, and high-rise buildings

• Nuclear power plants, large hydroelectric power plantsComprehensive pipe gallery settlement monitoring
