Classification: CPC G | IPC G

Claim 0:
1. A measuring system for a physical variable, the measuring system comprising:
a housing;
a measuring tube comprising:
at least one tubular deformation body having a cross-section which is deformed at least partially in a defined manner deviating from a circular cross-section and which is configured to expand elastically under pressure;
two feed sections which are each attached to end sections of the deformation body and which each have a circular cross-section at outer edge sections thereof;
two sealing sections for sealingly coupling the measuring system to a process, the sealing sections being integrally formed to the outer edge sections of the feed sections; and
two molded support sections which carry the housing;

a measuring sensor system configured to measure values of at least one of a stretching or a widening at at least two points on a section of the deformation body; and
an evaluation unit configured to electronically evaluate measured values of the at least one of the stretching or widening and to output them as a measurement signal,
wherein the housing at least partially surrounds and stabilizes the measuring tube on an outside in a direction of extension of the measuring tube, and
wherein the housing is provided with a vacuum and/or a negative pressure compared to the outside atmosphere.
