Title:
LEVEL GAUGE CALIBRATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/231275
Kind Code:
A1
Abstract:
The present application relates to the technical field of instrument verification. Provided in the embodiments of the present application is a level gauge calibration device. The level gauge calibration device comprises at least a calibration container (100), a test container (200), a floating block (300), a measurement device (400), an adjustment device (500) and a control device (600). By providing a test container (200) that is in communication with a calibration container (100), the height of the liquid level in the calibration container (100) is the same as the height of the liquid level in the test container (200), so that the height of the liquid level in the calibration container (100) can be obtained simply by measuring the height of the liquid level in the test container (200). By providing the floating block (300) and the measurement device (400), the measurement accuracy can be improved. By providing the adjustment device (500) and the control device (600), the control device (600) can control the adjustment device (500) to act according to the height of the liquid level in the test container (200) determined by the measurement device (400), so as to adjust the height of the liquid level in the calibration container (100). Therefore, through the mutual cooperation of the components, the calibration accuracy of a level gauge is improved.
