1. A method for identifying the concentration of fuels or gases in air comprising the steps of:
- conducting an air/fuel mixture whose concentration is to be identified through an ultrasound measuring section of known length;
directing ultrasound through said mixture in said measuring section;
determining the speed of sound through said air/fuel mixture; and
identifying the concentration of said mixture on the basis of the speed of sound through said mixture in said measuring section.
