Holding part and coriolis mass flowmeter having a holding part

A method for fabricating a Coriolis mass flowmeter having two parallel measuring pipes, the two measuring pipes being connected to each other by means of a holding part and held at a defined spacing from each other,

• wherein the holding part includes:
• a first holding ring having a first holding opening for a first one of the measuring pipes;
• a second holding ring having a second holding opening for a second one of the measuring pipes;
• a holding web firmly connecting the first and second holding rings and defining the spacing between the first and second holding rings;
• a first slot running radially and having a first slot width in the first holding ring;
• a second slot running radially and having a second slot width in the second holding ring;
• and
• a slot width changing device configured to simultaneously change the first and second slot widths and thereby change respective diameters of the first and second holding openings simultaneously, and
• wherein the method comprises:
• attaching the holding part to the two measuring pipes, a diameter of the first and second holding openings being greater than an external diameter of the measuring pipes;
• actuating the slot width changing device to reduce the diameter of the first and second holding openings, until the first measuring pipe is clamped firmly in the first holding opening and the second measuring pipe is clamped firmly in the second holding opening, each forming a soldering gap;
• and
• soldering the holding part to the first and the second measuring pipe along the soldering gaps.
