CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishPrimary 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.
