    • The invention relates to a method for dynamic wave form correction of a power supply of an induction heating device (3), a) where an input power signal (Uin), especially an input voltage signal, comprising waves with an input power frequency (fin) is provided by an AC power source (1), b) where a frequency converter (2) rectifies the input power signal (Uin) into a half waves signal (Uh), especially a half wave voltage signal, b1) where a half wave of the half waves signal is delimited by two subsequent zero-crossings (tθ, t1;t1, t2; t2, t3), b2) where the time lag between the two zero-crossings defines a half wave duration (th), c) where the frequency converter (2) further converts the half waves signal (Uh) into to a working signal (Iw), especially a working current signal, for supplying the induction heating device (3), d) where in a frequency shifting operation (5) a working frequency (fw) of the working signal (Iw) is first increased from a first working base frequency (f1) to a maximum frequency of (fmax) and then decreased to a second base frequency (f2) within a time, which is smaller than the half wave duration (th), e) where the first working base frequency (f1) is not equal to the second working base frequency (f2) and/or a zero crossing (t0, t1, t2, t3) of the half wave signal (Uh) is passed within the frequency shifting operation. Furthermore, the invention relates a an arrangement for dynamic wave form correction of a power supply of an induction heating device (3), particularly according to one of the preceding claims, a) with an AC power source (1) for providing an input power signal (Uin), especially an input voltage signal, comprising waves with an input power frequency (fin), b) with a frequency converter (2) for rectifying the input power signal (Uin) into a half waves signal (Uh), especially a half wave voltage signal, b1) where the frequency converter (2) preferably comprises at least one full bridge and/or at least one half bridge and/or a single switch, b2) where a half wave of the half waves signal is delimited by two subsequent zero-crossings (tθ, t1;t1, t2; t2, t3), b3) where the time lag between the two zero-crossings defines a half wave duration (th), c) where by the

    • A vortex flow meter for measuring the flow velocity of a fluid in a conduit includes a bluff body disposed in the flow passage of the conduit. The bluff body generates Karman vortices whose recurrence frequency is characteristic of the flow velocity to be measured. In the bluff body a cavity is formed which via passages communicates with the flow passage of the conduit and in the cavity a capacitive vortex sensor is disposed which converts the vortex pressure fluctuations originating from the Karman vortices to capacitance changes. The capacitive vortex sensor includes a first oscillating body in the form of a sensor sleeve which is deflectable by the vortex pressure fluctuations and an electrode holder which is disposed in the sensor sleeve and is formed as second oscillating body but is uncoupled from the vortex pressure fluctuations. The electrode holder carries at least one capacitor electrode which with an opposite electrode portion of the sensor sleeve forms a measured capacitance which varies on the deflections of the sensor sleeve relatively to the electrode holder caused by vortex pressure fluctuations. However, vibrations generated by external interfering influences cause similar deflections of the two oscillating bodies and thus do not result in any capacitance changes. The capacitive vortex sensor is thus insensitive to external vibrations and other interfering influences.
