| 20090266177 | CORIOLIS MASS FLOWMETER - A Coriolis mass flowmeter has a measuring tube that can be excited to oscillation, an oscillation driver and/or an oscillation sensor, wherein the oscillation driver and/or the oscillation sensor has a permanent magnet. The permanent magnet is arranged in a magnet holder so that a sure and simple fixation of the permanent magnet is achieved. | 10-29-2009 |
| 20100050783 | MASS FLOWMETER - 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. | 03-04-2010 |
| 20100326204 | METHOD FOR INSTALLING AND OPERATING A MASS FLOWMETER AND MASS FLOWMETER - A method for installing and operating a Coriolis mass flowmeter operating having a measuring tube, wherein the measuring tube is excited to vibrate, a phase shift of the vibration of the measuring tube which is dependent on the mass flow of the measuring tube or a corresponding time difference is determined, the temperature of the measuring tube is determined and the corresponding mass flow is calculated using the determined time difference and the determined temperature by means of a computation rule. Highly accurate measurements are possible in that in the computation rule, at least one known theoretical or empirical material temperature dependence influencing the mass flow is taken into account by determining a device-specific temperature dependence of the mass flowmeter influencing the mass flow through a subsequent calibration process and the known theoretical or empirical material temperature dependence and the device-specific temperature dependence are used in determining the mass flow. | 12-30-2010 |
| 20110219872 | METHOD FOR OPERATING A DENSITY MEASURING DEVICE AND DEVICE FOR DENSITY MEASUREMENT - 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. | 09-15-2011 |

| 20120079891 | CORIOLIS MASS FLOWMETER - A Coriolis mass flowmeter having at least four measuring tubes running parallel, the measuring tubes being joined in pairs into a oscillation unit by being inserted in openings in a holding device ( | 04-05-2012 |
| 20120192658 | CORIOLIS MASS FLOWMETER - A Coriolis mass flowmeter with at least four bent measuring tubes, at least one actuator assembly and at least one sensor assembly, wherein a first measuring tube and a second measuring tube are located in a common first plane and a third measuring tube and a fourth measuring tube are located in a common second plane, wherein the first plane and the second plane run parallel to one another, and wherein all four measuring tubes are joined together in terms of flow on the input side and on the output side with a collector. A Coriolis mass flowmeter for large amounts of flow, which is improved in respect to its measurement accuracy, is implemented in that the geometry and/or the surface characteristics of the measuring tubes are set so that the tube flow resistance of all four measuring tubes is identical. | 08-02-2012 |
| 20130042700 | CORIOLIS MASS FLOWMETER - A Coriolis mass flowmeter with a measuring tube through which a medium can flow, at least one actuator and at least one sensor, wherein the measuring tube is bent between its input and output ends into a first winding and a second winding, the first winding and the second winding merging into one another at a transitional section of the measuring tube. The first winding and the second winding run in parallel winding planes and wherein the first winding and the second winding can be excited to oscillation by the actuator and the oscillations detected by the sensor. The Coriolis mass flowmeter is comparably insensitive to the coupling of external oscillations in that oscillating sections of the first winding and the second winding are bent into a V shape that opens in a direction toward the transitional section of the measuring tube. | 02-21-2013 |
