Automatic verification/calibration device and method for glass floating meter

Abstract

The invention relates to an automatic verification / calibration device for a glass floating meter. An adjustable support is positioned at the middle upper part of a support frame; a first camera and a second camera are arranged on the adjustable support, the first camera and the second camera are located on the same horizontal plane, the first camera is used for collecting an image of the tangent position of a standard glass floating meter and the verification liquid level, and the second camera is used for collecting an image of the tangent position of the detected glass floating meter and the verification liquid level; an electronic balance and a non-contact diameter measuring instrument are separately connected with a data processing device through data lines, and a capillary constant correction value of the detected glass floating meter is obtained through operation; and the first camera and the second camera are connected with the data processing device through data lines, and the correction value of the detected glass floating meter is calculated according to the indicating value of the standard glass floating meter, the indicating value of the detected glass floating meter and the capillary constant correction value. The invention further relates to an automatic verification / calibration method for the glass floating meter. Errors caused by manual reading are reduced, and the amended value of the floating meter is automatically calculated.

Description

technical field [0001] The invention belongs to the field of measurement and metrology science and technology, and in particular relates to an automatic verification / calibration device and method of a glass buoyancy meter, which can realize automatic reading of the glass buoyancy meter and automatic calculation of correction values, and is used for automatic verification / calibration of the glass buoyancy meter . Background technique [0002] The glass float meter is an instrument that can float vertically and freely in the liquid, and directly measure the density, relative density or solution concentration of the liquid by the depth it is immersed in the liquid. Glass float gauges are widely used in the field of density measurement of petroleum products, battery solutions, pharmaceuticals, beverages, milk, vegetable oils, etc. The measurement results of the glass buoy meter are not only related to the quality control and production process management of semi-finished and fi...

AI Technical Summary

Problems solved by technology

The operation process of the direct comparison method is simple, but it requires the verification personnel to manually read, weigh the mass of the buoyancy meter, measure the diameter of the verification / calibration point, and calculate the correction value. Taking a set of second-class standard density meters as an example, there are hundreds of calibration points , each calibration point needs to be read and calculated, which consumes a lot of time for the staff, and manual reading has large errors and low efficiency

There are a large number of glass buoy gauges in the country, and tens of thousands of buoy gauges need to be verified / calibrated every year, and the workload of measurement personnel is very heavy
