Claim 15:
16. The measuring system according to claim 1, wherein the evaluation unit is configured to evaluate stretchings and/or widenings of the deformation body of the measuring tube based on:
data recorded by an optical measuring system;
data captured by laser optics, the laser optics carrying out a reference measurement on the basis of laser radiation guided via mirrors and/or a direct measurement based on laser radiation guided via one of a beam splitter and a common passage via at least three mirrors;
data recorded by at least one capacitive sensor;
data captured by at least one strain-sensitive optical fiber sensor which is wound around the measuring tube;
data recorded by two or four strain gauges;
data recorded by a Wheatstone bridge, which is formed from strain gauges; and/or
data recorded by at least one surface acoustic wave sensor.
