Abstract
In a method for measuring a distance from a base area (5) to a cross section, with a predefined diameter (A), of a tapering area (1.1) of a body (1), which tapering area forms an elevation or depression and has a circular cross-sectional form, a measuring body (3) with a diameter (A) is arranged on the base area (5). The arrangement is effected in such a manner that a distance in the form of a gap (6, X) is formed between the cross-sectional area, with the diameter (A), of the body (1) and the measuring body (3). A fluid medium is pressed through the gap (6, X) and the pressure and/or the flow rate of the fluid medium is/are measured. The distance value is determined in an evaluation device (9) on the basis of the measured pressure and/or the flow rate.
