摘要: A high-accuracy EGR sensor is provided. recirculation system provided which controls the flow rate of by use sensor. thermal gas flowmeter includes a heating resistor disposed in to be measured for detecting gas, and an external circuit electrically connected outputting signal according using resistor. The controlled heated at temperature equal or higher than vapor film forming film.
