    摘要: A low-cost thermal flow meter that has good temperature characteristics and little variations. The thermal flow meter includes a sensor element including a heat-generating resistor and at least two temperature-measuring resistors disposed downstream and upstream. The sensor element is positioned in the flow of a measured medium. It also includes an adjusting means for adjusting a excess temperature (ΔTh=Th−Ta) of the heat-generating resistor, which is the difference between the temperature (Ta) of the measured medium and the temperature (Th) of the heat-generating resistor. The adjusting means adjusts the excess temperature (ΔTh) of the heat-generating resistor depending on the temperature of the measured medium such that the excess temperature becomes smaller as the temperature of the measured medium increases.

    摘要: A thermal type air flow meter that makes it possible to precisely and easily determine whether a sensor element is a non-defective or a defective by screening is provided. First and second diaphragm sections composed of an electrical insulating film are formed in a semiconductor substrate. A heating resistor and a resistor for intake air temperature sensor are disposed on them to obtain a sensor element for thermal type air flow meters. The length of the short sides W1 of the rectangular first diaphragm section is made substantially equal to the length of the short sides of the second diaphragm section rectangular as well. Thus, the pressures applied to each of the diaphragm sections are substantially identical with each other in pressurization during screening.

    摘要: A thermal type flow sensor measures a flow rate of a fluid by means of a heat resistive element having a temperature dependency. The sensor is comprised of: plural heat resistive elements used for a flow rate measurement; and a driver circuit for controlling a current applied to these heat resistive elements to cause their heating. The driver circuit is configured to sense a resistance change of a lower-temperature side heat resistive element among the plural heat resistive elements and to control the current to be applied to the plural heat resistive elements in accordance with a sensed value of the lower-resistance's variation.
