Abstract
In a direct-heated flow measuring apparatus including an electric heater of a film resistor type and a temperature-detecting resistor for detecting the temperature within a passage, the flow rate thereof is measured by a sensing circuit. The temperatures of the electric heater and the temperature of the temperature-detecting resistor are compared. The measuring operation of the sensing circuit is stopped when the temperature within the passage is abnormal as indicated by this comparison.
