    • The device for measuring the internal diameter of tubes 2 consisting of two interconnected measuring units 3 and 4 that are connected to one another. The first measuring unit 3 is formed by a measuring head 9 in conjunction with a displacement transducer 7, which is axially displaceable within a tube 2. The axial displacement of the measuring head 9 is determined by a length measuring device consisting of a friction wheel 25 associated with a rotation transducer. To achieve this, the friction wheel is in functional connection with a flexible tube 24 which is rigidly connected to the measuring head 9. Thus, this measuring device makes it possible to determine internal diameters at two positions located at axially spaced locations from one another in a tube 2.
