20080314161 | MICROFLUIDIC DEVICE AND MICROTUBE THEREFOR - A microfluidic device for assessing properties of a fluid. The device utilizes a microtube capable of different vibration modes for promoting certain performance and/or structural aspects of the device. The microtube is supported by a base so as to be spaced apart from a substrate surface. The microtube has a peripheral portion surrounding the base, arms supporting the peripheral portion from the base, and a continuous internal microchannel having at least first and second microchannel portions. Each microchannel portion defines a separate flow route, and each flow route originates at the base, continues through a portion of the peripheral portion, and returns to the base. The first and second microchannel portions are fluidically connected to inlet and outlet ports, respectively, within the base. Vibration of the microtube is induced and sensed by driving and sensing elements. Fluid properties are determined from outputs of the sensing elements. | 12-25-2008 |
20090249890 | Method for operating a measuring device arranged on a rotating, carousel-type, filling machine - A method including: at least one oscillation measurement signal serving as primary signal of first class representing vibrations of a measuring tube, through which medium to be measured is momentarily flowing; and at least one oscillation measurement signal serving as primary signal of second class representing vibrations of at least one measuring tube, especially of the same measuring transducer, and orbiting around the axis of rotation of a carousel-type filling machine orbiting, but not containing flowing medium. Furthermore, based on both the primary signal of first class as well as also the primary signal of second class, at least one measured value, representing a measured variable, especially a mass flow rate and/or an integrated mass flow and/or a density of medium to be measured, is generated. Additionally, an apparatus is provided suited for reducing the method to practice and/or embodied as a carousel-type filling machine. | 10-08-2009 |

20100018326 | Coriolis effect mass flow meter and gyroscope - A Coriolis effect device includes a housing defining an interior chamber having a central axis, an inlet, an outlet, a leading disc and a trailing disc. Each disc is supported for oscillatory movement within the interior chamber of the housing. The leading disc defines a leading flow path in fluid communication with the inlet and interior chamber, wherein a portion of the leading flow path extends radially with respect to the central axis. The trailing disc is axially spaced from the leading disc. The trailing disc defines a trailing flow path in fluid communication with the interior chamber and the outlet, wherein a portion of the trailing flow path extends radially with respect to the central axis. A phase difference between leading and trailing oscillating signals picked up from the disc movement can be used to determine a mass flow rate of fluid passing from the inlet to the outlet. | 01-28-2010 |

20120060626 | METHOD FOR DETECTING PLUGGING IN A CORIOLIS FLOW MEASURING DEVICE - A method for detecting complete or partial plugging of a measuring tube of a Coriolis flow measuring device, which is insertable into a pipeline, and which has a measuring transducer of the vibration type having at least two measuring tubes connected for parallel flow. The method includes, in such case, the steps of measuring a subset flow occurring in a subset of the measuring tubes, and comparing a subset flow value obtained from this measurement with a reference value to be expected for this subset. The reference value is, in such case, determined from a total mass flow determined in the context of a Coriolis mass flow measuring. Additionally, the method includes the step of detecting plugging of at least one measuring tube of the measuring transducer, if the subset flow value deviates from the reference value by more than a limit value. | 03-15-2012 |
20120103110 | Mass flow measurement and measuring apparatus having a central bulk material feed - The present invention relates to a method and an apparatus for measuring a mass flow of flowable bulk materials according to the Coriolis principle of measurement. The apparatus comprises a vane wheel by which a mass flow that is supplied in axial direction can be radially redirected and by which it is possible to detect the drive torque that that necessary to achieve the redirection. A drive shaft that is routed through the top side of the housing is configured as a hollow shaft through which the bulk material can be fed to the vane wheel in vertical direction toward the center of its axis of rotation. | 05-03-2012 |
20120118077 | MULTIPHASE METERING SYSTEM - A multi-phase fluid is passed through a Coriolis flowmeter and a watercut meter. The multi-phase fluid includes two phases during a first time period and three phases during a second time period. It is determined that the multi-phase fluid includes two phases during the first time period, and a first value of a parameter of the multi-phase fluid is determined using a value measured by the Coriolis flowmeter during the first time period. A second value of a parameter of the multi-phase fluid is determined using a value measured by the watercut meter during the first time period. The first value is compared to the second value, and it is determined, based on the comparison, that the first value and the second value are inconsistent with each other. | 05-17-2012 |
