摘要： An apparatus for determining and/or monitoring mass flow of a fluid medium through a pipeline, or through a measuring tube. The apparatus includes two temperature sensors and a control/evaluation unit. The two temperature sensors are arranged in a region of a housing facing the medium and in thermal contact with the medium flowing through the pipeline, or through the measuring tube. A first of the temperature sensors is heatably embodied. A second of the temperature sensors provides information concerning the present temperature of the medium. The control/evaluation unit, on the basis of primary measured variables, such as temperature difference between the two temperature sensors and/or heating power fed to the first temperature sensor, ascertains the mass flow of the medium through the pipeline. The control/evaluation unit, in ascertaining the mass flow, provides a correction value for the mass flow and/or for the primary measured variable and/or for a measured value derived from the primary measured variable. And, the control/evaluation unit, in ascertaining the correction value, takes into consideration heat exchange by forced convection and heat exchange by free convection between the temperature sensors and the medium.

The apparatus includes two temperature sensors (11, 12) and a control/evaluation unit (10). The two temperature sensors (11, 12) are arranged in a region of a housing (5) facing the medium (3) and in thermal contact with the medium (3) flowing through the pipeline (2), or through the measuring tube. A first of the temperature sensors (11) is heatably embodied. A second of the temperature sensors (12) provides information concerning the present temperature of the medium (3). The control/evaluation unit (10), on the basis of primary measured variables, such as temperature difference (ΔT=T2−T1) between the two temperature sensors (11, 12) and/or heating power (P) fed to the first temperature sensor (11), ascertains the mass flow of the medium (3) through the pipeline (2). The control/evaluation unit (10), in ascertaining the mass flow, provides a correction value (K) for the mass flow and/or for the primary measured variable (ΔT, P) and/or for a measured value derived from the primary measured variable (ΔT, P). And, the control/evaluation unit (10), in ascertaining the correction value (K), takes into consideration heat exchange by forced convection and heat exchange by free convection between the temperature sensors (11, 12) and the medium (3).

摘要： This sensor (10) generates accurate measuring results, for example with an error in the order of 0.5% of the measuring value, hat has mimimized production costs as well as a shorter overall length compared to that of conventional sensors. The sensor has two parallel V shaped measuring tubes (1, 2) each being of one-piece construction. Each tube has a straight inlet portion (11, 21), a straight outlet portion (12, 22), an inlet bend (13, 23) connected with the inlet portion, an outlet bend (14, 24) connected with the outlet portion, a straight tube portion (15, 25) connected with the inlet bend, a straight tube portion (16, 26) connected with the outlet bend, and a vertex bend (17, 27) connected with the first and second straight tube portions. The inlet portions (11, 21) are fixed in an inlet manifold (18) and the outlet portions in an outlet manifold (19); the manifolds (18, 19) are mounted in a support frame (30) which forms part of a housing (3). An excitation arrangement (6) causes the measuring tubes (1, 2) to vibrate as a tuning fork. Interspaced sensor elements (7, 8) are fixed to the measuring tubes. Mounted in the support frame (30) is a feedthrough (37) for a printed-circuit board (96) having conducting tracks (97) to which leads (63, 64, 73, 74, 83, 84) of the excitation system (6) and of the sensor elements (7, 8) are connected.

摘要： A method for signal processing of measurement signals of a vortex flow transducer for measuring flow of a medium through a measuring tube. The method is characterized by low needs as regards computing power and memory space. The transducer includes a bluff body arranged in the measuring tube and a sensor for registering pressure fluctuations arising at the bluff body and for converting such pressure fluctuations into an electrical measurement signal. In the method, at least a portion of the measurement signal is sampled and digitized, an autocorrelation of the digitized measurement signal is calculated, and the flow is derived on the basis of at least one characteristic of the autocorrelation.

摘要： The vortex flow sensor is designed to measure the mass flow rate, the volumetric flow rate, or the flow velocity of a fluid flowing in a flow tube having a tube wall, and has two temperature sensors arranged in such a way that the vortex flow sensor may also be used with fluids which would corrode the temperature sensors. A bluff body in the flow tube sheds vortices and thus causes pressure fluctuations. A vortex sensor device responsive thereto is fitted downstream of the bluff body in a hole provided in the wall of the flow tube. The vortex sensor device comprises a sensor vane extending into the fluid. The temperature sensors are disposed in a blind hole of the sensor vane. Alternatively, the temperature sensor may be disposed in blind hole of the bluff body.

摘要： A flow meter includes a flow sensor for conducting fluid in a measuring direction and an opposite measuring direction, alternatively. Evaluation electronics coupled to the flow sensor generate a sensor signal corresponding to the flow rate of the fluid. A first subcircuit converts the sensor signal to a flow rate signal and a second subcircuit coupled to the first subcircuit generates an output signal representing the flow rate in the measuring direction. A third subcircuit fed by the flow rate signal delivers a control signal for controlling the generation of the output signal. The third subcircuit determines a flow when the fluid flows in the measuring direction and a counterflow when the fluid flows in the opposite direction, and calculates a balanced flow therefrom. Depending on the balanced flow, the third subcircuit controls the second subcircuit with the control signal to generate the output signal in a predetermined manner.

摘要： A vortex flow pickup serves for measuring mass flow, volume flow or flow velocity of a fluid which is flowing in a measuring tube having a tube wall, and has a temperature sensor arranged in such a way that the vortex flow pickup may also be used together with those fluids which corrode the temperature sensor. A bluff body which produces vortices, and consequently pressure fluctuations, is arranged in the measuring tube. A vortex sensor responding to these pressure fluctuations is fitted downstream of the bluff body in a bore of the tube wall of the measuring tube. The vortex sensor comprises a diaphragm which covers the bore and on which a sensor vane protruding into the fluid is fastened. The temperature sensor is fixed on the bottom of a blind hole of the sensor vane. On the side of the diaphragm lying opposite the sensor vane, a sensor element is fastened. The temperature sensor may alternatively be arranged in a longitudinal bore of the bluff body.

摘要： A Coriolis-type mass flow sensor (1) is disclosed which is as insusceptible to external disturbances as possible and which can be installed in a conduit and, during operation, is traversed by a fluid to be measured. The conduit is connected via a fluid inlet (113) and a fluid outlet (114) with a casing (11) in which a rigid support base (12) is disposed. The support base (12) is connected with the casing via at least one mechanical damping element (13, 14, 20). A measuring tube (15) traversed by the fluid ends in the fluid inlet and the fluid outlet. A portion (151) of the measuring tube which is to be set into vibration is attached to the support base by an inlet-side fixing means (121) and an outlet-side fixing means (122). An inlet-side connecting portion (152) of the measuring tube extends from the inlet-side fixing means (121) to the fluid inlet (113), and an outlet-side connecting portion (153) extends from the outlet-side fixing means (122) to the fluid outlet (114). A vibrator assembly (16) for vibrating the tube portion (151) acts between the casing (11) and the support base (12). Two vibration sensing elements (17, 18) mounted partly on the tube portion (151) are disposed near the inlet-side fixing means (121) and near the outlet-side fixing means (122), respectively.
