СПОСОБ ГРАДУИРОВКИ РОТАМЕТРОВ ГАЗА

摘要

FIELD: measuring technique. ^ SUBSTANCE: method comprises causing the gas to flow through the rotameter to be calibrated under excess pressure, separating the flow into several partial branches, measuring partial flows by means of connecting the standard flow meter to the collector. The rate of the flow through the flow meter is assumed to be the sum of the rates of the partial flows. ^ EFFECT: expanded functional capabilities. ^ 1 dwg
