ADDITIONS TO THE RULES FOR CHECKING METERS OF THERMAL ENERGY AND HOT WATER

摘要

The necessary additions to the rules for checking instruments for measuring thermal energy and hot water are considered. The impossibility in principle of interchanging them, based on the results of checking, is emphasized. The requirements imposed on thermal power meters and their units when delivered for checking and on the accompanying documentation are formulated. The rules for checking and electing matched pairs of thermal converters of resistance and the rules for adjusting and selecting matched pairs of electromagnetic flow meters are presented.
