Abstract: A vibrating meter comprises a vibrating element with a longitudinal direction and a cross-sectional area in a plane perpendicular to the longitudinal direction. The vibrating element moves between a first position and a second position in a plane perpendicular to the longitudinal direction of the vibrating element. An electronics is operable to drive the vibrating element between the first position and the second position. A boundary element and the vibrating element define a fluid velocity boosting gap having an average gap distance between the boundary element and the vibrating element. The vibrating element includes a gap-facing perimeter section facing the fluid velocity boosting gap having a gap perimeter length. In embodiments, a ratio of the gap perimeter length to the average gap distance is at least 160. In further embodiments, the average gap distance is 0.25 mm or less.

Abstract: The measuring system comprises a vibration-type transducer having a tube assembly, an exciter assembly and a sensor assembly, and a measuring system electronics unit electrically coupled to the exciter assembly and the sensor assembly. The measuring system electronics unit is configured to energize vibration exciters of the exciter assembly in a first operating mode such that the tubes perform out-of-phase mechanical vibrations with a frequency predefined by the drive signal, and to receive and evaluate vibration measurement signals representing vibration movements of the useful vibrations. The measuring system electronics unit is further configured to energize the vibration exciters in a second operating mode such that the tubes perform in-phase forced mechanical vibrations with a frequency predefined by the drive signal, and to receive and evaluate vibration measurement signals representing vibration movements of the useful vibrations.

Abstract: A thermal flow meter for measuring a flow rate of a gas includes: a measurement channel for guiding the gas between a channel inlet and a channel outlet; a thermal flow sensor disposed in the measurement channel; a density sensor including an oscillator operable to be acted upon by the gas; a temperature sensor element configured to determine a gas temperature; a pressure sensor element configured to determine a gas pressure; and a measuring-operating circuit configured to: determine a density value of the gas based on a natural frequency of the oscillator; identify a composition of the gas based on the density value, the gas pressure, and the gas temperature; and as a function of the composition, output a flow rate measured value corrected with respect to a cross-sensitivity of the flow rate to the composition of the gas based on flow rate-dependent signals of the thermal flow sensor.

Abstract: Provided are systems and method for dosing a pharmaceutical formulation. These methods and systems can displace the pharmaceutical formulation through a density flow meter, wherein the density flow meter is configured to measure a density of the pharmaceutical formulation. Next, the pharmaceutical formulation can be dosed into preformed molds and the dosing process can be stopped when the density of the pharmaceutical formulation measured by the density flow meter is below a predetermined threshold.

Abstract: Described is a device for measuring fluid density. The device is a flow meter including a housing with one side configured to mount to a flow conduit and define an outlet flow orifice near one end of the housing. The other side defines an inlet flow orifice near another end of the housing. The housing permits fluid to be introduced into the inlet flow orifice, flow through a flow cavity, and pass from the outlet flow orifice. The flow meter also includes a sensor head near the outlet flow orifice. The sensor head vibrates at a frequency upon introduction of electrical power while in contact with a fluid, detects the vibration frequency of the sensor head, and transmits the detected vibration frequency, which is associated with a density of the fluid. A system and method for determining a fluid density of a fluid using the described device is also disclosed.
