Abstract
The invention discloses a hydrostatic level gauge on-line calibration system and a calibration method thereof. The hydrostatic level gauge on-line calibration system and the calibration method thereofare used for measuring and calibrating a working level gauge. The hydrostatic level gauge on-line calibration system comprises a standard displacement generating device, a reference level gauge, a water tank, a water divider and a data acquisition unit. The calibration method comprises the steps that the standard displacement generating device is installed in a measurement site, the reference level gauge is fixed to the standard displacement generating device, and the water tank, the working level gauge and the reference level gauge are connected through the water divider; the height of the standard displacement generating device is slowly adjusted in the vertical direction in sequence, and after the system is stabilized, readings of the working level gauge, the reference level gauge andthe standard displacement generating device are measured through the data acquisition unit; and calculation is carried out according to a plurality groups of measurement data, and a calibration coefficient of a to-be-calibrated working level gauge is given. According to the calibration method, the calibration principle is simple, the overall operation is easy, the site working level gauge which cannot be detached can be calibrated online, off-line level gauge indoor calibration can further be carried out, and through the cooperation with the adjustment of the standard displacement generating device, the measurement accuracy is very high.
Description
technical field [0001] The invention relates to the technical field of calibration and measurement, and more specifically relates to an online calibration system and a calibration method for a static level, which is also applicable to offline indoor calibration of a static level. Background technique [0002] A hydrostatic level is a precision liquid level measurement system designed to measure the relative settlement of two or more measuring points. The energy level system is based on the use principle of the connector. The liquid level of the system is always kept horizontal under the condition of no pressure static force. The static characteristics of the liquid level of the public system. , this change in liquid level is sensed by the measuring instrument. Generally, the change of the liquid level is measured by a vibrating wire force sensor or other working principle equipment such as LVDT. [0003] Static leveling systems are widely used in large-scale projects and c...
