| A method (1) for determining the compressibility of a flowing fluid comprises the following steps: driving a volume flow of the fluid by means of a pump through at least one measuring tube of a vibronic density meter at a first pressure which is maintained by means of a throttle; determining a first density measurement value of the flowing fluid at the first pressure (10); determining a first pressure measurement value of the flowing fluid at the first pressure (10); driving a volume flow of the flowing fluid by means of a pump through a density meter at a second pressure which is maintained by means of a throttle; determining a second density measurement value of the fluid at the second pressure, which differs from the first pressure (20); determining a second pressure measurement value of the flowing fluid at the second pressure (20); determining the compressibility of the fluid based on the first density measurement value, the second density measurement value, the first pressure measurement value, and the second pressure measurement value, under the assumption that the composition of the fluid is unchanged between the detection of the first density measurement value and of the second density measurement value (30). | ||||||

| There is provided an apparatus for detecting the deteriorating health of a patient receiving gas from a respiratory device. The apparatus comprises a sensor unit configured to monitor a flow rate or pressure of a gas that is flowing in a pipe that connects the respiratory device to a gas delivery device worn by the patient, and a processor configured to measure a respiratory rate of the patient based on variations in the flow rate or pressure of gas in the pipe and to implement a trend analysis of the measured respiratory rate. The processor is configured to generate a warning when it determines that there is an upward trend in the measured respiratory rate and that a magnitude of the trend exceeds a threshold. | ||||||

| The sensor module (S) is used to record at least one parameter, for instance a flow velocity and/or a volume flow rate, of a fluid (FS) flowing in a pipeline and for this purpose comprises a main body (G S), which is placed in a lumen of the pipeline and has a flow path (K S), which extends therein from an inlet opening (ES) to an outlet opening (A S) remote from the latter and therefore communicates with the lumen of the pipeline and is intended to guide a fluid partial volume (FS') branched off from the fluid flowing in the pipeline, as well as a converter element (Ws) which is arranged on the flow path and is intended to generate at least one sensor signal which is influenced by the fluid guided in the flow path. The flow path has an inflow region (EK) which opens into the inlet opening, an outflow region (A K) which opens into the outlet opening, and a straight intermediate region (Z K) which communicates with the inflow region and the outflow region. In the sensor module according to the invention, the flow path is also designed such that an imaginary central axis (L Z) of the intermediate region is not parallel to an imaginary central axis of the inflow region (L E) and/or is not parallel to an imaginary central axis of the outflow region (L A). | ||||||

This invention provides a flow measuring device of a bypass structure that uses an orifice holding member to hold an orifice, the flow measuring device reducing a change of a flow ratio due to such as a production tolerance of the orifice holding member. A main flow channel (53) is provided for a flow channel block (52), and an auxiliary flow channel (56) is provided in parallel to the main flow channel (53). On a front portion of the main flow channel (53), a spacer container (74) having a C-shaped cross section is provided in a depressed manner along an outer circumference surface, and a portion where the spacer container (74) is not provided is configured as the flow channel wall (54). Out of a branch flow introduction channel (72) and a branch flow collection channel (73) that communicate the main flow channel (53) and the auxiliary flow channel (56), a branch entrance (72a) of the branch flow introduction channel (72) opens in the flow channel wall (54) at a front side of the main flow channel (53), and a collection exit (73a) of the branch flow collection channel (73) opens in the wall surface of the main flow channel (53) at a back side of the main flow channel (53). The orifice (63) is contained within the main flow channel (53) from the front side and brought into contact with a stopper section (75), and the orifice (63) is held by the end surface of an orifice supporting spacer (65) inserted into the spacer container (74) from the front side.

| A fluid flowmeter (10) comprises a frame (14) having a cavity that is open to one side thereof for the acceptance of a laminar flow module (16) and open to the other side for the acceptance of sensing electronics that measure pressure drop across the module.

A pump assembly comprises a pump with a stationary component (20) and a movable component (10) opposite thereto, which form a substantially wedge-shaped sliding space (50) among each other, in which sliding space a hydrodynamic supporting fluid film with a pressure distribution can build up during operation, with the stationary component (20) comprising an inlet arrangement (30) and an outlet arrangement (40), with the inlet arrangement (30) extending to an area of low pressures of the pressure distribution (110) in the sliding space (50), and with the outlet arrangement (40) extending to an area of high pressures of the pressure distribution (110) in the sliding space (50). A flow sensor produces a flow signal representing the volumetric flow rate of the flow generated by the pump. The flow signal is supplied to a comparator for comparing it with a nominal flow signal and for providing a control signal to an adjustable loading unit for the adjustable loading of the pump to provide an outflow of the pump according to the nominal signal. |

Device for measuring pressure differences or mass portions in a fluid flow - gas or liquid - and/or for implementing processes for mixing fluids, whereby when in use the fluid flows into the device, then passes a part therein where the fluid flow is laminar and the flow measurement is made, and finally flows out of the device, whereby the device has a turbulence filter which is integrated therein, with a settling chamber behind it. The fluid then first flows through that filter, so that a laminar flow leads to the flow measuring element. |

| Procédé et dispositif pour prélever des échantillons de liquide sur une conduite de passage menant d'un premier récipient à un second récipient. Lors du passage d'un volume de liquide à examiner, on dévie de la conduite de passage un volume représentatif du volume total du liquide transféré, on le rassemble et, à la fin du transfert, on prélève un volume partiel sur le volume total en tant qu'échantillon. Ce procédé et le dispositif qui sert à le mettre en oeuvre permettent notamment d'effectuer un prélèvement partiel de courant en n'importe quel endroit de la conduite de passage et de dévier un volume représentatif du volume de liquide à examiner pendant toutes les phases du transfert de ce liquide. A cet effet, le volume dévié est prélevé en continu de la conduite de passage selon un procédé connu en soi, la quantité dépendant de la pression de retenue; on adapte immédiatement la pression statique dans le volume dévié à la pression statique sur et par-dessus le liquide à proximité du point de prélèvement et on obtient une variable réglante servant à compenser la pression à partir de la différence entre les pressions statiques, cela sans que la pression soit compensée pour l'entrée et la sortie du liquide du volume dévié. Dans un dispositif de mise en oeuvre dudit procédé, on a notamment prévu une conduite de compensation de pression (6), qui débouche dans la tête d'un récipient (17), et un tube plongeur (17b), qui est relié à la conduite de passage (4) à proximité du point de prélèvement (I) et qui se prolonge jusque dans la partie inférieure du récipient (17). | ||||||

| Drag is produced in a gas stream by a bluff body (47), and is converted to low pressure stable and continuous vortices by a restriction (56). The difference in gas pressure is sensed (14) between a point (15) outside the flow passage in communication therewith and a point (16) inside the flow passage between the restriction and the bluff body. The resultant flowmeter may be connected in line (FIG. 1) or as a bypass (FIGS. 2 and 5) in a gas system. | ||||||
