Abstract

Primary standard flow meters are developed and maintained for the calibration of leak artefacts used in many applications in which the quantification of leakage is required. INRIM maintain a primary flowmeter based on constant pressure- changing volume in order to measure small gas flow of R134a referred to atmosphere (ambient pressure). In the framework of EURAMET project 1115 a comparison was organized by LNE. Other participants were PTB, INRIM, CMI. The laboratories have been performed measurements at two different R134a throughput levels 3.5 g/y and 1 g/y using a permeation leaks as transfer standards supplied by LNE.
Gas flow measurements performed at INRIM Istituto Nazionale di Ricerca Metrologica - Torino- Italy / Bergoglio, M.; Mari, D.; Streito, S.. - (2010).
