Measuring tube system, measuring tube and production method for a measuring tube system

A measuring tube system for a measuring device, comprising:

• an n-fold number of measuring tubes for conducting a flowable medium, wherein the measuring tubes each have two end regions, and wherein n>=1;
• a first block with an n-fold number of first channels passing through the first block, wherein the measuring tubes, in a first end region, are each at least partially conducted through the corresponding first channels and are integrally, frictionally, and/or form-fittingly fixed in the corresponding first channels;
• and
• a second block with an n-fold number of second channels passing through the second block, wherein the first block and the second block are arranged such that the first channels and the second channels correspondingly adjoin one another and the first block and the second block are connected in a fluid-tight manner.

A method for producing a measuring tube system, comprising:

• providing an n-fold number of measuring tubes, an n-fold number of sealing elements, a first block with an n-fold number of first channels passing through the first block, a second block with the n-fold number of second channels passing through the second block, and a connection element, wherein the measuring tubes each have two end regions for conducting a flowable medium, and wherein the sealing elements each have a first conical end region and a second conical end region, and wherein n>=1;
• integrally, frictionally, or form-fittingly connecting a first end region of the measuring tubes to the corresponding first channels;
• flanging the first end regions of the measuring tubes to form a conical flange;
• inserting the sealing elements between the first block and the second block such that the first conical end region of the sealing element terminates with the conical flange of the first end region of the corresponding measuring tube and that the second conical end region of the sealing element terminates with the conical taper of the corresponding second channel;
• attaching the connection element to corresponding receptacles of the first block and the second block;
• and
• forming a pressing force between the first block and the second block by tightening the connection element.

A measuring device for detecting a mass flow rate, a viscosity, a density, and/or a variable derived therefrom, of a flowable medium, comprising:

• a measuring tube system, including:
• an n-fold number of measuring tubes for conducting a flowable medium, wherein the measuring tubes each have two end regions, and wherein n>=1;
• a first block with an n-fold number of first channels passing through the first block, wherein the measuring tubes, in a first end region, are each at least partially conducted through the corresponding first channels and are integrally, frictionally, and/or form-fittingly fixed in the corresponding first channels;
• and
• a second block with an n-fold number of second channels passing through the second block, wherein the first block and the second block are arranged such that the first channels and the second channels correspondingly adjoin one another and the first block and the second block are connected in a fluid-tight manner;
• at least one vibration exciter which is designed to excite the measuring tubes to vibrate;
• at least one vibration sensor which is designed to detect at least one deflection of a vibration of the measuring tubes;
• and
• an electronic measuring and/or operating circuit designed to operate the at least one vibration sensor and the at least one vibration exciter and is connected thereto by means of electrical connections, wherein the electronic measuring and/or operating circuit is further designed to ascertain and provide the mass flow rate, the viscosity, and/or the density, and/or the variable derived therefrom, of a flowable medium.
