PERIODICAL CONTROL AND DYNAMIC TRACEABILITY TEST OF AN SNPS TO THE NATIONAL STANDARD OF GAS FLOWMETERS CALIBRATION

Alex S. Kun, Balazs Rekasi

Abstract

The tested Sonic Nozzle Prove ring System (SNPS) stepped into service at the Gas Works of Budapest almost five years ago. To keep its parameters in a dedicated and good condition a continuous checking process is carried out. During this checking process those tested were the SNPS main accuracy and repeatability, as well as the individual sonic nozzles (SN).
