摘要： The present inventive concept relates to a valve for controlling fluid flow. The valve comprises a valve body, a chamber arranged inside of the valve body, a fluid inlet for providing fluid to the chamber, and a fluid outlet for receiving fluid from the chamber. The valve further comprises a closing arrangement for controlling the flow of fluid from the fluid inlet to the fluid outlet via the chamber, and a differential pressure sensor for measuring the differential pressure over the closing arrangement, between an upstream pressure and a downstream pressure. The differential pressure sensor is integrated in the valve body, and is arranged to measure the differential pressure for at least an open state of the closing arrangement.

摘要： A device (100) for measuring the pressure of a fluid comprising a mantle region (200) defining a fluid conduit (210) and a detection system (600) comprising a measurement element (300), at least a first resilient element (700), and a target member (500), wherein at least a portion of the measurement element (300) is arranged inside the fluid conduit (210). The first resilient element (700) exerts a resilient force on the measurement element (300), the resilient force opposing at least a displacement of the measurement element (300) along a locating path (L) with respect to a neutral position. The target member (500) is arranged inside the fluid conduit (210),at least a first portion (510) thereof being arranged in a substantially fixed position with respect to the measurement element (300). The measurement element (300) comprises a first surface (320) and a second surface (330), wherein the first (320) and the second (330) surfaces are arranged generally opposite to one another. The device (100) further comprises at least a first position sensor (400) for evaluating the position of at least the first portion (510) of the target member (500) along the locating path (L), wherein the first position sensor (400) is arranged outside the fluid conduit (210) in a substantially fixed position with respect to the mantle region (200). Moreover, at least a portion of the measurement element (300) is movable along the locating path (L) by a displacement force acting on the measurement element (300). Said displacement force is generated by a difference between the local pressure of a fluid acting on the first surface (320) and the local pressure of a fluid acting on the second surface (330). The position of at least the first portion (510) of the target member (500) along the locating path (L) with respect to the first position sensor (400) depends on the displacement force.

摘要： The present invention provides a pressure change measuring apparatus and a pressure change measuring method, which are capable of detecting a change in pressure to be measured with respect to a time axis with high accuracy. Specifically, a reference value setting unit (60) included in a pressure change measuring apparatus (1) is configured to generate a reference value signal based on an output signal of a differential pressure measuring cantilever (4) under a predetermined state, and to output the reference value signal. An arithmetic processing unit (30) is configured to calculate the pressure change in pressure to be measured based on the output signal, the reference value signal, a volume of a cavity (10), a flowing quantity of a pressure transmission medium flowing into and out of the cavity (10) for every unit of a predetermined time period, and the like.
