Abstract

In a method for measuring the volume of a loaf of bread, a distance-measuring ultrasonic transducer (10) is kept at a known distance from a reference point (R) in the loaf during the entire measurement. Relative motion between the loaf (2) and the ultrasonic transducer (10) is generated, such that a measuring signal from the ultrasonic transducer (10) successively impinges upon essentially the entire surface of the loaf (2) during the relative motion. The distance from the ultrasonic transducer (10) to the loaf (2) is measured several times during the relative motion. Since the distance between the ultrasonic transducer (10) and the reference point is known, the distance from the reference point to a number of measuring points on the surface of the loaf can be determined on the basis of the distances measured by the ultrasonic transducer (10). A part volume of the loaf is determined for each measured distance from the reference point to the surface of the loaf, and the total volume of the loaf is then determined by adding up all the part volumes. A device for implementing the method is also disclosed.
