[0001] The utility model relates to the technical field of level calibration, in particular to a level meter calibration device. Background Art
[0002] At present, the static level, as a new type of level, is widely used in high-precision elevation measurement occasions because of its higher measurement accuracy. It adopts the principle of communicating vessels and liquid static pressure, and reflects the height difference or settlement of the ground by measuring the static pressure changes of the liquid at different heights. Therefore, when the monitoring point undergoes a longitudinal relative displacement relative to the reference point, it will cause the pressure change of the liquid inside the monitoring point. By measuring this pressure change, the rise and fall data of the monitoring point relative to the reference point can be calculated, thereby grasping the settlement and uplift information of the entire measured area.
[0003] At present, during the long-term use of the static level, the accuracy of its measurement data will decrease due to various factors such as wear and aging. For this reason, we propose a level meter calibration device. Utility Model Content
