摘要：
In order to take into consideration the different response by a hot wire sensor to changes in temperature of air as opposed to changes in temperature of fuel, the circuit configuration of a hot wire sensor for fuel flow detection differs from that for air flow detection in that an additional resistance is connected in series with the flow measuring resistance in the bridge circuit of the fuel flow detector, while the additional resistance is connected in series with the temperature compensating resistance in the bridge circuit of the air flow detector.
