球形金属罐是液化石油气及轻质液化化工产品等的贸易结算计量器具,其容量检定的准确程度直接关系到交接计量的准确程度,影响企业的经济效益。本文通过对几种赤道直径和竖向直径测量方法的探讨,了解各种方法的测量条件和利弊,指出研究新型球形金属罐直径测量方法的必要性。
The spherical metal cans are trade settlement measuring instruments such as liquefied petroleum gas and light liquefied chemical products. The accuracy of capacity verification is directly related to the accuracy of the transfer measurement and affects the economic benefits of the enterprise. In this paper, we discuss the measurement conditions, advantages and disadvantages of several methods for measuring the equatorial diameter and vertical diameter, and point out the necessity of studying the new method for measuring the diameter of the spherical metal can.
