<p>PURPOSE:To detect the intake air flow of an automobile with high accuracy even when the air flow abruptly changes by absorbing noise associated with the variation of the air flow while the air flow strongly varies. CONSTITUTION:The title flowmeter uses a temperature sensitive resistor RR for detecting air flow rate and is provided with a capacitor C5 between the (-) and (+) input terminals of the amplifier OP1 of a feedback circuit which controls the heat generation of the resistor RR.</p> |
