摘要:
A thermal type flow meter has a first heating resistor (1), a second heating resistor (6) for blocking heat transfer from the first heating resistor to a console, a temperature measuring resistor (9) interposed between the two heating resistors, and a controller for calculating a flow rate unrelated to temperatures of fluid from temperatures of the resistors and currents supplied to the heating resistors (1,6).
