    Abstract: A Coriolis mass flow meter comprises a vibration element, an exciter assembly, a sensor assembly, and an electronic transformer circuit electrically coupled to the exciter assembly and the sensor assembly. The vibration element is contacted by the flowing fluid. The exciter assembly is designed to convert electric power into mechanical power to produce mechanical vibrations of the vibration element. The transformer circuit generates an electric driver signal and feeds electric power to the exciter assembly. The vibration element mechanically vibrates with a vibration frequency specified by the electric driver signal. The sensor assembly has two electrodynamic vibration sensors designed to convert vibrational movements of the vibration element at a first or at a second measurement point into electric vibration measurement signals having an AC voltage component with a frequency and with an amplitude based on the frequency and on a magnetic flux flowing through the respective vibration sensor.

    Abstract: The method of the present disclosure is used to monitor a condition of a measurement sensor comprising an oscillator, which has a measuring tube for conveying the medium, and a condition parameter dependent upon a further physical parameter. The method comprises: determining tuples containing a value of the physical parameter and an associated value of the condition parameter; assigning the tuples to a value range of the physical parameter; and forming a reference value of the condition parameter for this value range of the physical parameter using the value of the condition parameter when no valid reference value of the condition parameter for this value range is present; or comparing the value of the condition parameter of the tuple with the reference value when a reference value of the condition parameter for this value range is present; and generating a finding on the basis of the result of the comparison.
