摘要： A mass flowmeter employing the Coriolis principle incorporates in at least one section two measuring tubes that extend along a common plane, as well as a connecting device that connects the two measuring tubes in the section in which they extend along the common plane. The connecting device is designed and positioned in a manner whereby its flexural strength for flections in the common plane of the measuring tubes is greater than its torsional rigidity for torsional oscillations around the connecting line between the two measuring tubes. This achieves good frequency separation between the excitation oscillations generated in the common plane of the measuring tubes and the oscillations of the measuring tubes perpendicular to the former.

摘要： A mass flowmeter for measuring the flow of fluids, operating by the Coriolis principle and designed for mounting on a fluid-carrying, preferably straight pipe, with at least one detector capable of measuring Coriolis forces and/or Coriolis-force-induced oscillations of the pipe, and with a bridge. The detector is attached to the bridge and the bridge is mountable on the pipe. The mass flowmeter is compact and can be mounted on existing pipes of a conduit system due to a design that permits radial attachment of the bridge on the pipe.

摘要： A method of testing a mass flow rate meter functioning on the Coriolis principle, in which an apparatus of the mass flow rate meter is subjected to a predetermined oscillation excitation and the associated oscillation response is recorded. Then the recorded oscillation response is compared with a previously recorded oscillation response. Testing of the Coriolis mass flow rate meter with regard, for example, to error tolerances in the manufacturing or with regard to a calibration condition is thereby enabled.

摘要： A rigid central manifold block defines a coaxial inlet and outlet of the flowmeter and supports at least one continuous conduit loop substantially encircling the block and having its inlet and outlet ends closely spaced and rigidly connected to the block. Preferably, the loop includes a straight section perpendicular to the inlet and outlet ends. Dual drive means are preferably provided for oscillating the straight section back and forth about its perpendicular bisector and complementary position detectors employed at or near the opposite ends of the straight section, preferably at the same location as the drive units, provide readouts which are combined algebraically and synchronously demodulated to yield a Coriolis-related output indicative of mass flow. Preferably, a second loop, identical and parallel to the first, is supported by the same block. The block is channeled to serve as a manifold and interchangeable manifolds are disclosed for series and parallel flow through the two loops, respectively. The plane of the loop or loops can be oriented perpendicular or parallel (in line) to the process line.

摘要： 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.
