Abstract
This method of fastening a metal body to a an outer circumference of a single straight measuring tube, consisting of titanium or zirconium, of a Coriolis-type mass flow sensor does not need any heating, for example soldering, welding or brazing, process. The metal body has a circumferential surface and a bore adapted to the outer circumference. The metal body cooperates with an exciter arrangement or with a sensor arrangement or serves as a cantilever mass or as an end piece of the measuring tube. The metal body is pushed on to the measuring tube and is subsequently pressed on to the latter at ambient temperature. A pressure sufficient for fastening but not reducing substantially the lumen of the measuring tube at the fastening position is exerted on at least part of the circumferential surface.
