The invention relates to a Coriolis measuring sensor for detecting a mass flow rate or a density of a medium flowing through a measurement tube of the Coriolis measuring instrument. The measurement tube has an inlet and an outlet designed to convey the medium between the inlet and the outlet; an exciter; and two sensors; the measuring sensor comprising a supporting element having a chamber designed to house the measurement tube at least in portions. The magnet device comprises a magnetically conductive holder for magnets and a first pair of magnets arranged on the holder on a first face of the coil device, with the magnets designed to cause a magnetic field perpendicularly to a cross-sectional plane of the coil, and the magnetic field of a first magnet of the pair is oriented so as to be opposite to the magnetic field of a second magnet of the pair.

An adapter includes several connecting nozzles. Free nozzle ends of the connecting nozzles are adapted to be connected to line ends of fluid lines. The adapter includes, for guiding flowing fluid in and then out, two mutually separated, tubular flow channels. Moreover, the adapter includes a projection, which extends from the nozzle end with a length to a free projection end remote therefrom. A fluid line system formed by means of the adapter comprises, furthermore, a fluid line with, enveloped by a wall, a lumen. The fluid line can be connected with its line end to the connecting nozzle of the adapter in such a manner that the projection protrudes inwardly into the lumen of the fluid line to form two tubular chambers of the fluid line mutually separated by the projection and adapted for guiding through flowing fluid.

A measuring system for measuring at least one measured variable of a flowing fluid, comprises a fluid supply line, a transducer apparatus, which has a tube and at least one other tube and is adapted to deliver at least one measurement signal corresponding to the at least one measured variable, a fluid return line, and a fluid withdrawal line. To open a first flow path, which leads from the lumen of the fluid supply line to the lumen of the tube, further to the lumen of the tube and further to the lumen of the fluid return line, equally as well not to the lumen of the fluid withdrawal line, and thereafter to allow fluid to flow along the flow path for the maintaining the temperature and/or for cleaning of parts of the measuring system and/or for conditioning fluid. It is, additionally, provided (instead of the first flow path) thereafter to open a second flow path, which leads from the lumen of the fluid supply line to the lumen of the first tube and, in parallel, to the lumen of the second tube and further from the lumen of the first tube, and from the lumen of the second tube, in each case, to the lumen of the fluid withdrawal line, as well as to allow fluid to flow along the second flow path. Moreover, it is provided, while allowing fluid to flow along the second flow path, in given cases, also while allowing fluid to flow along the first flow path, to generate at least one measurement signal, as well as to use the measurement signal for ascertaining measured values of the at least one measured variable.
