Air-gauging method for measuring the internal cross section or diameter of a bored hole, especially for holes with diameters in the sub-millimeter range, whereby a fluid is forced past a blocking body inserted in the hole

Method for measuring a cross section or diameter (12), in which a probe body (30) with a closed surface is inserted into the inner space and a fluid with a predefined pressure is forced past the probe body. The narrowing caused by the probe body inserted in the inner space causes a counter pressure...
