THE NEW INRIM PRIMARY STANDARD OF WATER FLOW RATE

Carlo Marinari

Abstract

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.
