- Sensor 100 includes four curved measuring tubes 101, 102, 103, 104.
- the measuring tubes 101, 102, 103, 104 extend between an inlet-side collector 120 and a
- Outlet-side collector 120 and are fixedly connected to the collectors 120, for example by rolling, brazing or welding. Between the collectors 120 extends a solid support tube 124 which is fixedly connected to both collectors, whereby the collectors 120 are rigidly coupled together.
- the carrier tube 124 has at its upper side openings through which the measuring tubes 101, 102, 103, 104 are guided out of the carrier tube 124 and back again by the collectors 120.
- the collectors 120 each have a flange 122 at the end, by means of which the sensor 100 is to be installed in a pipeline. Through openings 123 in the flanges 122, a medium is to be guided through the measuring sensor 100, in particular its measuring tubes 101, 102, 103, 104, in order to determine the mass flow rate and / or the density of the medium.

- the measuring tube center lines are in each case opposite through the centers of a sequence of tube cross sections along the course of a measuring tube.
- Each of the measuring tubes 101, 102, 103, 104 is assigned a measuring tube longitudinal plane Syz-1, Syz-2, Syz-3, Syz-4, to which the integral of the distance squares of the respective measuring tube center line is minimal.
- the measuring tube center lines can run completely in the respective measuring tube longitudinal plane.
- the measuring tube longitudinal planes Syz-1, Syz-2, Syz-3, Syz-4 intersect the measuring tube transverse plane Sxy vertically, as shown in FIG. 2b, which shows a plan view of the measuring tube transverse plane.
- each measuring tube has its own measuring tube long plane Syz-1, Syz-2, Syz-3, Syz-4, wherein the measuring tube transverse planes can quite coincide in pairs, as in Fig 2a for the symmetries of the embodiment of FIG a to 1d is shown. Accordingly, the first and fourth measuring tube long plane lie in a common measuring tube long plane Syz 1-4 and the third and second measuring tube long in a common measuring tube long plane Syz-3-2.
- Each of the measuring tube center lines 1 1 1, 1 12, 113, 1 14 extends symmetrically to a common measuring tube transverse plane Sxy, which is therefore cut perpendicularly from the Meßrohrmittenlinien.
- the first measuring tube center line 11 1 and the third measuring tube center line 113 extend symmetrically with respect to a sensor longitudinal plane Syz-0.
- the second measuring tube center line 112 and the fourth measuring tube center line 114 run symmetrically with respect to the sensor longitudinal plane Syz-0.
- the measuring tube longitudinal planes Syz-1, Syz-2, Syz-3, Syz-4 run in the first embodiment parallel to the sensor longitudinal plane Syz-0.
- the first measuring tube 101 and the third measuring tube 103 are each connected to two nodal plates 131 and 133 on the inlet side and the outlet side, wherein the position of the two inner of the nodal plates 131, that is, by those on the inlet side or outlet side furthest away from the corresponding collector 120 are free vibration lengths of the first measuring tube 101, and the third measuring tube 103 are fixed.
- the second measuring tube 102 and the fourth measuring tube 104 are each connected on the inlet side and outlet side to two nodal plates 132 and 134, the nodal plates 132 being free due to the position of the two inner ones
- Vibration lengths of the second measuring tube 102, and the fourth measuring tube 104 are fixed. Due to the symmetries, the measuring tubes longitudinally symmetrical to each other extending measuring tubes each have the same oscillation length and thus the same except for minimal deviations due to manufacturing tolerances
- Vibration characteristics that is to say, for example, without the oscillation couplers 212, 234, they would have substantially the same eigenfrequencies in pairs, which in each case are determined in particular by the free oscillation lengths of the measuring tubes are fixed.
- the two pairs of measuring tubes have different oscillation properties and in particular different natural frequencies, the aim being to minimize the differences as far as possible hold. Due to the coupling of the measuring tubes by the two vibration couplers 212, 234 to the first and second oscillators 01, 02, the measuring tubes oscillate in bending modes of the oscillators resulting from coupling the bending modes of the measuring tubes involved.
- the bends have natural frequencies that differ from those of the flexural vibration modes of the coupled measuring tubes.
- the so-called Nutzmode ie that Biegeschwingungsmode in which measuring tubes are usually excited in a generic sensor, split by the coupling of the measuring tubes in two bending modes of the oscillators, oscillator oscillation modes on short.
- a first oscillator oscillation mode the first oscillator 01 oscillates against the second oscillator 02, with the two measuring tubes of an oscillator each oscillating in phase, that is, moving simultaneously in the positive X direction.
- a second oscillator oscillation mode the first oscillator 01 oscillates against the second oscillator 02, with the two measuring tubes of an oscillator each oscillating in antiphase, that is to say moving simultaneously in the opposite X direction.
- the second oscillator oscillation mode has a higher natural frequency than the first oscillator oscillation mode. How strongly the eigenfrequencies of the first and second oscillation oscillation modes differ from each other depends on the stiffness of the
- Vibration coupler in relation to the rigidity of the measuring tubes. Design options for this are shown below. In either case, the frequency separation should be a multiple of a resonant width of the oscillator modes to prevent crosstalk between the oscillator modes.
- the coupling of the measuring tubes to two oscillators causes the measuring tubes to oscillate in defined phases relative to one another and that the vibration modes do not interfere with each other.
