Problems solved by technology

This method brings the disadvantages of high cost and low work efficiency to liquid level gauge manufacturers.
Often in order to calibrate a liquid level gauge, it is necessary to repeatedly fill and empty the calibration tank, which leads to low work efficiency and waste of energy.
While tank liquids are reusable, filling and emptying also wastes a lot of electrical energy

Abstract

The invention discloses a liquidometer calibration device. The liquidometer calibration device is simple in structure, is easy to operate, and is stable and reliable in data. The liquidometer calibration device includes vertical guide rails at two ends and a lifting work platform; two ends of the lifting work platform are each provide with a displacement sensing mechanical amplifier; each displacement sensing mechanical amplifier includes a displacement sensing disc, the displacement sensing disc is coaxially connected to a raster conversion disc, the displacement sensing disc is connected to the two ends of the lifting work platform through a central rotation shaft, the circumference surface of the displacement sensing disc is positioned on the corresponding vertical guide rail; when the lifting work platform moves vertically, the displacement sensing discs slide along the vertical guide rails and then drive the raster conversion discs to rotate at the same time; the two ends of the lifting work platform are each provided with a pulse digital converter; an outer circle of each raster conversion disc is provided with a rectangular tooth groove; and the pulse digital converters are corresponding to the rectangular tooth grooves of the raster conversion discs.

Description

technical field [0001] The invention relates to a verification or calibration device for a liquid level (material level) measuring instrument in the field of automatic instruments, in particular to a verification or calibration device for an instrument with a relatively high liquid level detection range. Background technique [0002] At present, in the field of automatic measuring instruments, the verification or calibration of liquid level gauges or liquid level detection instruments is usually calibrated by a detection device that simulates a liquid level storage tank on site to perform actual liquid level changes. This method brings the disadvantages of high cost and low work efficiency to liquid level gauge manufacturers. Often in order to calibrate a liquid level gauge, it is necessary to repeatedly fill and empty the calibration tank, which leads to low work efficiency and waste of energy. While storage tank liquids are reusable, filling and emptying also wastes a lot...
