摘要： A gas flow measuring apparatus includes first and second temperature dependent resistors located in a gas tube respectively downstream and upstream of an electric heater which is also located in the gas tube. The first and second temperature dependent resistors are connected to form a bridge circuit together with first and second reference resistors. Between a pair of diagonal junctions of the bridge circuit, a potential difference is produced depending on the flow rate of the gas and the power supplied to the electric heater, and a measuring circuit controls the power supplied to the electric heater so that the potential difference is maintained at a predetermined value irrespective of a change in flow rate of the gas. The measuring circuit includes a chopper circuit to convert the potential difference into a square wave having a peak-to-peak value substantially equal to the potential difference and having a center reference level of the square wave corresponding to a voltage level determined by a reference voltage generator and an adder circuit. The square wave from the chopper circuit is then amplified and half rectified and applied to a sample-hold circuit to produce a voltage signal representative of the potential difference. A differential amplifier having two inputs of the voltage signal from the sample-hold circuit and a predetermined voltage produces an output signal which is used to control the power supplied to the electric heater. A current flowing into the electric heater is used to determine the flow rate of the gas.

摘要： A gas flow measuring apparatus for measuring intake air flow for an automobile engine having an electrical heater resistive member, and first and second temperature dependent resistive members. The first resistive member is located so as to be well influenced by heat from the heater resistive member, while the second resistive member is located so as to be little influenced by the same. The measuring apparatus measures a gas flow rate by using an output signal from a voltage dividing circuit as a series circuit of the first and second resistive members. In the gas flow measuring apparatus, a heater film resistive member is deposited on a first support member by an evaporation depositing or printing process, and is further covered with electric insulating material such as glass. The first resistive member is formed on the heat resistive member, with the insulating material interposing therebetween, whereby the close proximity of the heater resistive member to the first resistive member is realized, and the second resistive member is formed on a second support member.
