Abstract: A Coriolis mass flowmeter (1) having at least one curved measuring tube (2), at least one oscillation generator (3), at least one oscillation sensor (4), at least one measuring device electronics (5) and a housing (6). To provide the housing (6) with increased pressure resistance, in particular against external positive pressure, the housing (6) has a first housing shell and a second housing shell, the first housing shell and the second housing shell completely surrounding the measuring tube (2) so as to form at least a first pressure-resistant hollow space around the measuring tube (2), and the first housing shell and the second housing shell forming a bridge (13) between the inlet (10) and the outlet (11) of the measuring tube (2).

Abstract: A method for operating a density measuring device having a measuring tube filled with the medium for determining the density of the medium, in which the measuring tube is incited to vibrate, the frequency of the vibration determined and the density of the medium being calculated from the determined frequency and other parameters which determine the physical-geometrical properties of the measuring tube. In particular, at least one mechanical stress of the measuring tube is determined, and with the obtained mechanical stress value, the influence of the mechanical stress of the measuring tube and/or the influence of the pressure in the medium on the determined density of the medium are or is—at least partially—taken into consideration or compensated.

Abstract: A mass flowmeter is provided which operates on the Coriolis principle, having (1) at least four measurement tubes which can oscillate and through which a medium can flow, (2) at least one oscillation generator for excitation of the oscillations of the measurement tube, and (3) at least one oscillation sensor for detection of the excited oscillations of the measurement tubes. The measurement tubes are preferably arranged closely in parallel such that the flow cross section covered by the measurement tubes covers as small an area as possible. The use of four or more compactly arranged measurement tubes advantageously allows for the measurement of a high mass flow rate with measurement tubes having a relatively small cross section and length, resulting in a mass flowmeter having compact length and width dimensions, and which requires only a relatively low energy oscillation generator for excitation of the oscillations of the measurement tubes.
