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 |

20110184667 | METHOD FOR DETERMINING AT LEAST ONE CHARACTERISTIC FOR THE CORRECTION OF MEASUREMENTS OF A CORIOLIS MASS FLOWMETER - A method for determining at least one characteristic for the correction of measurements of a Coriolis mass flowmeter which is characterized by an increased accuracy and a low error rate while determining the characteristic is implemented by detecting values of a measurand during constant flow with the reading sensors, calculating at least one location parameter from the detected values, an calculating at least one dispersion parameter from the detected values and the location parameter. The detection of additional values and the calculation of the location parameter and dispersion parameter from the existing and additional values is carried out until the dispersion parameter reaches a threshold value, and then, the location parameter corresponding to the dispersion parameter is used as the characteristic for the correction of the reading of the Coriolis mass flowmeter. | 07-28-2011 |
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 |
