Coriolis measuring transmitter and Coriolis measuring device

A Coriolis measuring transmitter of a Coriolis measuring device for measuring a mass flow or a density of a medium flowing through a pipe, the measuring transmitter comprising:

• at least one pair of measuring tubes arranged to oscillate relative to each other, wherein each measuring tube includes a central bend, wherein in an equilibrium position, the measuring tubes of the at least one pair of measuring tubes are symmetrical with respect to a symmetry plane extending between both measuring tubes;
• at least one driver configured to oscillate the measuring tubes;
• at least two sensors configured to measure the oscillations of the measuring tubes;
• and
• two guiding devices configured and arranged to guide the medium, wherein one guiding device is configured and arranged to guide the medium from the pipe into each measuring tube, and wherein the other guiding device is configured and arranged to guide the medium from each measuring tube into a continuation of the pipe,
• wherein each guiding device comprises a fluid chamber with a first opening configured to connect to the pipe and with second openings for each measuring tube, the second openings each configured to connect to a measuring tube of the at least one pair of measuring tubes,
• wherein each guiding device comprises multiple parts, wherein a first part is configured to connect to the pipe and wherein at least one second part is configured to connect to the measuring tubes of the at least one pair of measuring tubes,
• wherein in a projection of the fluid chamber onto the symmetry plane, the fluid chamber follows a chamber bend connecting a measuring tube volume with a pipe volume, and
• wherein the first part and the at least two second parts are connected together leak-tightly by a corresponding interface, wherein each interface comprises a protrusion and a recess at least partially complementary to the projection.
