Class Information
Number: 73/1.16
Name: Measuring and testing > Instrument proving or calibrating > Volume of flow, speed of flow, volume rate of flow, or mass rate of flow
Description: Subject matter wherein either (a) the apparatus for proving or calibrating or (b) the device being proven or calibrated determines (1) a size or extent of flow of a fluent material, (2) a rate of flow of a fluent material, (3) a rate of motion of a specific dimensional amount of a fluent material, or (4) a response of a fluent material due to an acceleration other than in the normal direction of flow of the fluent material.
