Abstract: A vibronic sensor for measuring mass flow rate, includes a measurement pipe, an excitation magnet and a sensor magnet, an excitation coil and a sensor coils, each having an elongated basic shape. The basic shape has a center of gravity through which a largest diameter having a length d1 and a smallest diameter having a length d2 extend, wherein the excitation coil or the sensor coil has a first coil axis and a second coil axis in a cross-sectional plane. The largest diameter d is in the first coil axis, wherein the smallest diameter d2 is in the second coil axis. For a quotient d1/d2, the following applies: 1.15≤d1/d2, where, when the measurement pipe vibrates in an in-plane mode, a deflection direction of the measurement pipe is oriented in parallel with the first coil axis in a region of the excitation magnet or the sensor magnet.

Abstract: An arrangement includes a pipeline and a Coriolis volumetric flow meter for measuring a mass flow rate of a medium flowing through the pipeline. A first pressure sensor is attached at an inlet-side of the pipeline and a second pressure sensor is attached at an outlet-side of the pipeline, or wherein a differential pressure sensor is configured to detect a difference between an inlet-side and an outlet-side. The pressure sensors and/or the differential pressure sensor are configured to measure a media pressure and to determine, for each differential pressure, a volumetric flow velocity of the medium through the pipeline. A first monitoring sensor is attached at an inlet-side portion of the pipeline and a second monitoring sensor is attached at an outlet-side portion of the pipeline, wherein the monitoring sensors are configured to monitor a measurement variable different from the media pressure to identify a static media state.
