Patent ID: 7136777

Claim:
A Coriolis mass flowmeter incorporating at least one measuring tube, at least one oscillator for the excitation of the measuring tube and at least one oscillation detector for registering the oscillations of the measuring tube, with an activator serving to energize the oscillator, at least one evaluation unit serving to analyze the oscillations registered by the oscillation detector, an excitation signal path including excitation signal-path devices provided between the activator and the oscillator for transmitting an excitation signal, and a measuring signal path with measuring signal-path devices provided between the oscillation detector and the evaluation unit for transmitting the measuring signal, the improvement wherein a control signal path with at least one control signal path device is provided, which control signal path connects the excitation signal path directly to the evaluation unit, whereby the excitation signal traveling through a minimum of one excitation signal path device is fed as a control signal, via the control signal path, to the evaluation unit, said control signal path device in the control signal path corresponding to a measuring signal path device.
