摘要: A method for measuring the flow rate of fluid such as liquified petroleum gas fuel for an automobile fuel. A signal of the fluid flow rate and a signal of the fluid temperature are produced by using the signals from an electric heater and a first, second, and third temperature-dependent resistors in a signal processing circuit. The produced signals are supplied to a computer circuit to carry out modification, linearization, and multiplication by a conversion constant for linearization which is corrected regarding temperature characteristic. The result of calculation in the computer circuit is displayed on a display device.
