| Abstract: | Using the principle of forced convection of platinum-film temperature sensors at high temperatures,a kind of platinum-film gas flowmeter applied to automobiles is designed.A large number of tests on the temperature characteristics of the heat probe and experimental research of the temperature compensation performance for the flowmeter's outputs have been carried out.The results of tests show that the design of the temperature compensation influences the flowmeter's output performance directly.Platinum-film gas flowmeters with good design can be well applied to automobile electric spraying systems. |
