A multi-point thermal gas-mass flowrate measurement method is designed. The meter has four hot-film sensoring elements. Four often-used arrangements of the sensing elements are studied and the optimal disposition is selected. The temperature characteristics of the hot-film probe are analyzed under different surrounding temperature conditions and different currents passing through the hot-film probe...
