PARALLEL CONNECTION MEASURING METHOD FOR GAS LEAKAGE BASED ON STANDARD FLOW

抄録

The objective of work described in this paper is to propose a new method of measuring gas leakage for pneumatic industry. The measurement is enabled by employing standard flow. Standard flow is used to determine the internal volume of the measured equipment. An algorithm is formulated to describe, to the extent possible, the relationship between gas leakage and standard flow. This measurement method deviates from the theoretical leakage values by less than 5%, and shows a good precision and scope compared with the traditional flow measurements. In addition, the proposed parallel connection based on standard flow makes easy operation and fast measuring possible, thus promising new area of application for pneumatic equipments.
