Methodology for metrological maintenance of matched pairs of flowmeters used at centres for commercial thermal energy metering

摘要

An automated version of adjustment and development of matched flowmeters pairs with the use of a special help software is suggested. The succession of actions which are made by the verifier carrying out the adjustment of instruments using the help software has been demonstrated for electromagnetic flowmeters as an example. The verification and subsequent adjustment, if needed, of the matched pairs of flowmeters are also presented by the software procedure with the description of main metrological and information criteria.
