ABSTRACT:
An air flow sensor and a temperature sensor of a device for measuring air flow in the intake manifold of an internal combustion engine are mounted in parallel relation to one another in a plane of a flat holder member. The sensors are secured to the holder member in fixed manner by adhesives. The mounting of the sensors on the holder can be achieved by mass production with the sensors aligned in the common plane in parallel relation to one another. In one embodiment the sensors are secured to the upper and lower legs of a rectangular frame with an intermediate leg of the frame disposed between the sensors.
