Rate of air flow measuring system for IC engine using circuit module

摘要

The circuit module (14) with the three elements is fixed at the air duct (1). The circuit module is fixed at the outer wall surfaces of the air duct. The module is connected electrically to the heat resistor (2) and the temp. sensor resistor (3). An integrated element consisting of a holding element of the heat resistor also a holding element of the thermistor (8) is inserted through an opening (6) in the wall of the air duct.
