规定了一种通过测量在已知时间间隔内输送至称重箱的水的质量来确定满载管道中流体流量的方法。该应用通常适用于流速小于1500 kL/s的固定实验室装置。该应用与ISO 4185:1980相同，并根据ISO 4185:1980复制。

Specifies a method for the determination of fluid flow, in a conduit running full, by measurement of the mass of water delivered into a weighing tank in a known time interval. The application is generally for fixed laboratory installations with flow rates of less than 1500 kL/s. It is identical with and has been reproduced from ISO 4185:1980.
