Abstract

A Sonic Nozzle Prover System (SNPS) stepped into service at Gas Work of Budapest. After a two-years of operation a Round-robin test was made to control the basic accuracy and repeatability. The test involved the National Standard gas meter calibration system 1 and the SNPS. Also a new one - which operation just going on - based on PD master meter was tested. The calibration systems working at low pressure using vacuumed and pressure controlled flow circle. The twin meters has temperature compensators. Repeatedly obtained tests based on twin meter package pointed out reasonable results.
