Method of measuring the volume of a bakery product (2), comprising the stages that an ultrasonic transmitter (10) for measuring destance is held at a known distance from a reference point (R) in the bakery product throughout the measurement, a relative movement is created between the bakery product (2) and the ultrasonic transmitter (10) so that essentially the entire surface of the bakery product is struck successively during the relative movement by a measuring signal from the ultrasonic transmitter, the distance for the path of the measuring signal from the ultrasonic transmitter (10) to the surface of the bakery product 82) is measured repeatedly during the relative movement, the volume of the bakery product is calculated with the aid of the distances measured and the distance from the ultrasonic transmitter to the refeence point in the bakery product. According to the invention, the distance for the path of the measuring signal between the ultrasonic transmitter (10) and the surface of the bakery product (2) is set up to longer than the shortest distance between the ultrasonic transmitter and the surface of the bakery product in each given position of the relative movement. A device for executing the method is also shown. |
