Description

technical field [0001] The invention relates to the technical field of simulation experiments, in particular to an experimental platform for testing the accuracy of a hydraulic static level. Background technique [0002] The static level is a high-precision liquid level measuring instrument, which is used to measure the relative settlement of each measuring point of the foundation and the building. The hydraulic static level uses a hydraulic sensitive unit to measure the pressure change value of the liquid reservoir at each measuring point relative to the The change of the reference point calculates the pressure change of each measuring point, and then solves the settlement change. The application site includes large buildings, such as hydropower plants, dams, high-rise buildings, nuclear power plants, water conservancy projects, railways, subways, high-speed rails and other measuring points for uneven settlement measurement. When applied to the construction site, the error...

Problems solved by technology

When applied to the construction site, the error of the entire test system of the hydraulic static level is often increased due to environmental factors, and even effective data cannot be tested. Therefore, an experimental platform for testing the accuracy of the hydraulic static level is needed to test environmental factors. Effect on Measurement Accuracy
