The separate phase model of two-phase flow and the thermal characteristics of low plessure wet steam show that orifice can be used as a practical heatmeter for measuring heat transmitted by wet steam. As a heatmeter, it is not sensitive to steam quality. Under industrial boiler operation conditions, its theoretical error is less than 0.01. The principle described in this paper makes it possible to measure heat transmitted by wet steam directly and the difficulty of measuring mass flow rate of two --phase flow...
