Study of natural gas parameters in expansion coefficient narrowing devices for diagnosing domestic gas meters

A.G. Vynnychuk
Annotations languages:

The possibility of applying the method of alternating pressure differential diagnosis for domestic gas meters was considered. Application of correction factor for the calculation of the expansion narrowing devices by changing working environment (air, natural gas) in diagnosing devices was proposed. The results of modeling of the expansion coefficient and correction factor expansion socket narrowing devices was following.
