Study of Calculation Methods of Heat Transmission of Heat Meters

摘要

This paper describes the researches of the calculation method of heat transmission of heat meters: Enthalpies difference method and heat coefficient method are the same in nature, each method can be chosen at different conditions. While consulting the heat coefficient table, the flow measuring position corresponding to the heat coefficient should be consistent with the installation position of the flow sensor, otherwise correction should be carried out to avoid the errors.
