The INRIM Water Flow Rate Primary Standard revamping
INRIM – Istituto Nazionale di Ricerca Metrologica, 91 strada della Cacce , 10135 Torino, Italy
In 2011, INRIM opened a noteworthy upgrading work to plane an extensive renovation of the national water flow rate primary standard, to get better its structural features and to increasing its metrological performance. The paper presents the main activity of revamping of the INRIM liquid flow calibration rig in order improve its flow rate range and, mainly, to update its ancillary instrumentation towards a more modern approach to signal conditioning, by introducing automatic and user-friendly control of the measurement-taking process.An evaluation of uncertainty propagation in flow rate measure using a Monte Carlo method is adopted.
