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 mass flow/density sensor which can be installed in a pipe and through which a fluid to be measured flows during operation is balanced over a wide density range so that accurate measurements are possible. The Coriolis mass flow/density sensor includes a measuring tube, an excitation arrangement for exciting the measuring tube to vibrate in a second fundamental flexural mode of vibration; and a counterbalance member attached to the measuring tube which counterbalances the vibration of the measuring tube. A cantilever can be attached to the measuring tube midway between the inlet end and the outlet end of the measuring tube. First and second sensors sense the measuring tube vibration on the inlet and outlet sides of the measuring tube, respectively.
