ABSTRACT:
A flow rate measuring device, especially for measuring the flow rate of incoming fresh air in the induction tube of an internal combustion engine in which a temperature-dependent sensor, e.g. a resistor, is exposed to the air flow while the current through the sensor is controlled and monitored to obtain a signal related to the air flow rate. In order to prevent damage to the sensor from high-temperature flame fronts due to backfiring and also from inadvertent mechanical contact with tools, etc., there is provided at least one protective element downstream of the sensor and possibly another element upstream. The protective element is a plate-like barrier permitting essentially unimpeded air flow. The pattern of the element may be a grid or sieve, a honeycomb pattern or a plurality of parallel tubes.
