ABSTRACT:
An air flow measuring apparatus having a measuring plate provided within an air intake pipe and a potentiometer having divided resistor material, a slider support member and switching contacts in which the shaft of the measuring plate and the shaft of the slider support member of the potentiometer interlock with each other, and corresponding electrical signals are produced from the potentiometer in accordance with the pivotal movement of the measuring plate, which pivotal movement is proportional to the intake air flow. With this construction, highly accurate measurement of the intake air flow is possible even with low manufacturing cost for the apparatus.
