摘要： A thermal type gas flow measuring instrument measures gas flow with high precision by accurately correcting changes in radiation heat characteristics of a heating resistor due to contamination. The instrument comprises a second heating resistor 30 whose resistance value, which changes if contaminated, is calculated by measuring the terminal voltage thereof by calculating means 32, and the calculated value is compared with a temperature detected by a temperature detecting element 31. Based on the result of comparison, the level of contamination of the second heating resistor 30 is determined. The second heating resistor 30 and the first heating resistor 3 are disposed in similar environments such that their levels of contamination can be considered equal.

摘要： A thermal type air flow measuring instrument is mounted to a main passage forming an intake air passage of an internal combustion engine and is provided. with an auxiliary passage which includes a heating resistor and a temperature sensing resistor therein and an electronic circuit which is electrically connected to the heating resistor and the temperature sensing resistor. The auxiliary passage is a passage including at least one bent portion composed of a first path substantially parallel to the main passage and a second path having a path different in flow direction from the first path. A member forming the auxiliary passage is fixed in a united form to only a case member for interiorly protecting the electronic circuit, and the case member is fixed to the outer wall surface of the intake air passage. The auxiliary passage structure capable of being handled as a single module united to the case member is effective to the mass production of an air flow control system and the reduction in cost thereof since the structure can be mounted to different kinds of internal combustion engines.
