The measuring apparatus such as heat meter is legally obliged to be installed and used for heat rating for each dwelling in centralized residential buildings in Korea. Heat meters with mechanical working parts such as impeller, at present widely used in residential buildings in Korea, have caused some critical troubles, such as errors of impeller working, the insensitive response at low flow rate range and so on. For the sake of solving these problems, an electromagnetic heat meter was developed recently in KICT. A field test at the residential building complex were carried out in the present study to verify the influences on reliability of newly developed heat meters in various field conditions such as the pressure in pipe works, temperature and humidity of the installed circumstances, etc.. As results we found that heat meters installed H-apartment houses having been operated confidently in winter season. 2.4~13.8% of heating energy saving was also achieved through the mind inspiration.
