System and method for measuring volume of glass measuring ware

Abstract

The invention discloses a system and method for measuring the volume of glass measuring ware. The system is used for measuring the volume of liquid in the measuring ware, and comprises a cross-shaped laser measuring system, a standard glass measuring ware system, a standard metal measuring ware system, a work platform and a data processing system. The cross-shaped laser measuring system is used for measuring liquid level height, the standard glass measuring ware system is used for measuring the precision of the cross-shaped laser measuring system, the standard metal measuring ware system is used for outputting fixed-volume liquid, the work platform is used for allowing the cross-shaped laser measuring system to be installed, and the data processing system is used for processing the liquid volume and the liquid level height and building a volume table. Volume parameters with high precision are obtained based on the volume table built by the data processing system and precision measured by the standard glass measuring ware system in combination with the liquid level height measured by the cross-shaped laser measuring system. Automatic reading of the liquid level, capacity, temperature and other signals and real-time processing of data are achieved. Compared with a traditional measuring method, the technical problem of human errors in conventional measurement is solved, and measuring precision is greatly improved.

Description

technical field [0001] The invention relates to the field of volume measurement of glass gauges, in particular to a system and method for volume measurement of glass gauges. technical background [0002] The glass measuring device is a measuring device for measuring the volume of a liquid. It is widely used in the fields of chemistry, physics, biology, geology, medicine and metrology. It has a non-negligible position in the field of small-volume measurement. It is necessary to carry out metrological verification and calibration in accordance with the national verification regulations. The verification and calibration of glass gauges may seem simple, but in fact it is a very complicated task. At present, the verification and calibration methods of glass measuring instruments are mainly the measurement method and the volume comparison method, and most of the domestic verification departments adopt manual measurement methods, which makes the verification personnel heavy worklo...

AI Technical Summary

Problems solved by technology

In the prior art, the glass measuring instrument mainly judges the reading of the lowest point of the meniscus and the scale line by the eyes during measurement, so it can only roughly calculate the volume of the liquid to be measured in the measuring cylinder, and the reading error is large, so it cannot be used with ordinary The measurement principle is verified

If the measurement method is used for the verification and calibration of glass measuring instruments, this measurement principle is simple and accurate, but it is not easy to automate
