Abstract: At present, with the development of technology, heat meters have sparked a new round of technical discussions, and corresponding technical standards are gradually being updated. In the national standard GB/T 32224—2020 Heat meters, the minimum display resolution of heat meters in the cumulative heat calibration mode is left too small, which has a significant impact on indication errors. This article discusses the minimum resolution margin of heat meters, hoping to provide reference for the revision of national standards for heat meters.

Keywords: heat meter; calorific value; minimum resolution
