Modular measuring device
The present disclosure relates to a modular measuring device including: a measuring tube module, wherein the measuring tube module includes a fixing body arrangement; an oscillation exciter; at least one oscillation sensor; and a support module including a seat, wherein the measuring tube module is arrangeable in the seat of the support module, wherein the support module includes a fixing apparatus, wherein the fixing apparatus includes an at least sectionally eccentrically embodied shaft, wherein the fixing apparatus, especially the shaft, is adapted to clamp the measuring tube module via the fixing body arrangement in the seat and to connect the measuring tube module mechanically releasably with the support module.
1 . A modular measuring device for registering mass flow, viscosity, density and/or a variable derived therefrom for a flowable medium, modular measuring device comprising:
a measuring tube module configured to be a single-use article, wherein the measuring tube module includes at least one measuring tube configured to enable the medium to flow therethrough, wherein the measuring tube module includes a fixing body arrangement secured to the at least one measuring tube;
an oscillation exciter configured to excite the at least one measuring tube to execute oscillations, wherein the oscillation exciter includes an exciter magnet and an exciter coil, wherein at least one component of the oscillation exciter is arranged on the measuring tube module;
at least one oscillation sensor configured to detect oscillations of the at least one measuring tube, wherein in the at least one oscillation sensor includes a sensor magnet and a sensor coil, wherein at least one component of the oscillation sensor is arranged on the measuring tube module; and
a support module, which includes a seat, the sensor coil and the exciter coil, wherein the seat is configured to facilitate introduction of the measuring tube module in the support module,
wherein the support module includes a fixing apparatus, which includes a shaft, which is at least sectionally eccentrically embodied,
wherein the shaft is adapted to clamp the measuring tube module via the fixing body arrangement in the seat and to connect the measuring tube module mechanically releasably with the support module, and
wherein the shaft is embodied as a camshaft including at least one cam, and wherein the shaft is mounted on the support module.
2 . The modular measuring device of claim 1 , wherein the fixing body arrangement includes a depression configured, at least partially, complementary to the eccentric section of the shaft, and
wherein the depression is configured to form an at least shape-interlocking connection with the eccentric section of the shaft.
3 . The modular measuring device of claim 2 , wherein the depression of the fixing body arrangement is configured, at least partially, complementary to at least one cam of the eccentric section of the shaft, and
wherein the depression is configured to form the at least shape-interlocking connection with the at least one cam.
4 . The modular measuring device of claim 1 , wherein the shaft of the fixing apparatus is mounted movably in a longitudinal direction of the shaft.
5 . The modular measuring device of claim 4 , wherein the shaft is configured such that a movement in the longitudinal direction is possible, at least sectionally, exclusively in a discrete number of orientations.
6 . The modular measuring device of claim 5 , wherein the number of discrete orientations is exactly one orientation of the shaft.
7 . The modular measuring device of claim 5 , wherein the number of discrete orientations is exactly two orientations of the shaft.
