Abstract: Various embodiments of sensing devices are provided for determining water cut measurements of a fluid flowing through a fluid passageway. In some embodiments, the sensing device can include one or more pressure and/or temperature sensor probe assemblies configured to measure a pressure and/or temperature of the fluid, and a probe assembly configured to measure a water cut of the fluid.

Abstract: The present invention pertains to a pressure sensor for measuring absolute dynamic pressure. The sensor comprises a frame surrounding a diaphragm, wherein the diaphragm is spaced from the frame by at least two slits which define a restriction that places a reference chamber in fluid communication with a surrounding environment. The diaphragm is connected to the frame at two transition areas, which transition areas are separated from one another by the slits.

Abstract: A pressure sensor for measuring high pressures, the sensor being adapted to act externally on a measuring element, the measuring element having a central cavity and being composed of two parts which are sealingly joined in order to form the cavity, and comprising sensor means for measuring the mechanical stress condition of the measuring element. The two parts of the measuring element are manufactured in planar technology form silicium or quartz and have a substantially larger length than lateral dimensions, the cavity being oriented in a longitudinal direction, and the sensor means being piezo-resistive elements lying adjacent to the external or internal surface of the measuring element.
