摘要： The invention relates to a sensor assembly (11) comprising a deformation element (111) with two opposing surfaces (111+, 111#), an outer edge segment (111a), and a sensor vane (112) which extends from the surface (111+) up to a distal end and which comprises a left-side first lateral surface (112+) and a right-side second lateral surface (112#). The sensor assembly (11) further comprises an overload protection device (113), which extends from said edge segment (111a) up to a distal end, can be used to protect the deformation element (111) against plastic or irreversible deformation, and comprises a support bracket (113a) that is guided at a lateral distance from the sensor vane, and two stops (113b, 113c), which are supported on the support bracket for the sensor vane (112), wherein a first stop (113b) of the stops is placed on the left-hand side of the sensor vane and a second stop (113c) of the stops is placed on the right-hand side of the sensor vane. The stops (113b, 113c) are dimensioned and arranged such that an intermediate space (113') formed between the stops takes up solely a sub-region (112a) of the sensor vane (112). The deformation element and the sensor vane are additionally designed to vibrate about a common static rest position and in the process move relative to the overload protection device such that the sensor vane carries out oscillating movements which elastically deform that deformation element and during which the sub-region (112a) is alternately moved to the left, namely in the direction of the stop (113b), or to the right, namely in the direction of the second stop (113c). A sensor made with such a sensor assembly and a transducer element (12), which is coupled thereto and functions so as to generate a sensor signal that represents temporally changing movements of the sensor vane and/or temporally changing deformations of the membrane, or a measuring system made with said sensor and a measuring electronic system connected thereto can be used to detect pressure fluctuations in a flowing fluid, for example in a steam with an at least temporary temperature of 400 ºC and/or an at least temporary pressure of more than 140 bar, in order to measure a flow parameter of said fluid for example.

摘要： Der Wirbelfrequenz-Durchflußmesser hat einen Rohrkörper (12), der einen Strömungskanal (14) für das Medium aufweist, dessen Durchfluß gemessen werden soll. Im Strömungskanal (14) ist ein Staukörper (16) angeordnet, der Kármán'sche Wirbel erzeugt, deren Folgefrequenz der Strömungsgeschwindigkeit des Mediums proportional ist. Ein Sensor (30), der auf die von den Wirbeln erzeugten Druckschwankungen anspricht, ist in einem Hohlraum (20) angeordnet, der über Durchlässe (24, 26) mit dem Strömungskanal (14) in Verbindung steht, damit die Druckschwankungen in den Hohlraum (20) übertragen werden. Die Durchlässe (24, 26) sind durch ein Absperrorgan (34) verschließbar, das durch ein Betätigungsteil (38) von außen verstellbar ist. Dadurch ist es möglich, den Sensor (30) nach dem Verschließen der Durchlässe (24, 26) aus dem Hohlraum (30) zu entnehmen, ohne daß Strömungsmedium austreten kann.

摘要： The present invention provides a method for preventing frost damage to one or more flow meters installed in a fluid distribution network containing a fluid, wherein each flow meter is configured to measure a temperature, preferably an air temperature, and to wirelessly transmit the measured temperature, such as via a mobile or a fixed wireless reading system to a processing unit. The method comprises: 1) during a period continuously monitoring (M_TMP) the temperatures measured by the plurality of flow meters over a period of time, 2) performing a data analysis (P_DA) on the temperatures of the plurality of flow meters from the period, 3) based on the data analysis, identifying (I_FDC) one or more ones of the plurality of flow meters as frost damage candidates in a future frost period, and 4) transmitting (T_WS) a warning signal indicative of the frost damage candidates or initiating frost protection measures to protect the frost damage candidates. It has been found that it is possible to monitor temperatures in a no-frost period to identify a frost damage candidate, e.g. if a flow meter is positioned in a pit and the lid is removed thereby causing the risk of a frost damage of the flow meter.

摘要： A subsea flow meter assembly (100) for measuring the flow of a medium is provided. The subsea flow meter assembly (100) has a pipe section (101) extending in an axial direction and providing a flow path for a medium. At least four measuring ports (11, 12, 13, 14) are provided at different locations in the pipe section (101). A first sensor assembly (20) is configured to measure at least a differential pressure between a first and a second measuring port (11, 12) and an absolute pressure at one of the first and second measuring ports (11, 12). A second sensor assembly (30) is configured to measure at least a differential pressure between a third and a fourth measuring port (13, 14), and an absolute pressure at one of the third and fourth measuring ports (13, 14). A first measuring unit (50) is mounted to the pipe section (101) and configured to take measurements of the differential pressure and the absolute pressure by means of the first sensor assembly (20). A second measuring unit (60) is mounted to the pipe section (101) and configured to take measurements of the differential pressure and the absolute pressure by means of the second sensor assembly (30). An evaluation unit of each measuring unit (50, 60) determines a flow rate of a flow of medium through the pipe section (101) based on the pressure measurements.
