  • Patent number: 5253533
    Abstract: A mass flow meter for flow media which works primarily on the Coriolis Principle has a pipe inlet, a straight pipe carrying the flow medium, a pipe outlet, an oscillation generator operating on the pipe and two transducers detecting preferably Coriolis forces and/or Coriolis oscillations affecting Coriolis forces. The flow meter has a relatively low natural frequency at a certain layout length or a relatively short layout length at a certain natural frequency, and in this way, the oscillation generator engages the pipe via an articulated arm so that the conduit is excited to torsional and bending vibrations.

  • Patent number: 5052231
    Abstract: In a Coriolis mass flow gauge, the signal from each sensor is digitized and converted into digital measuring values by one or more analog/digital converters operating with a specific digital sampling frequency. Then, using a microcomputer, each digital measuring value thus obtained is multiplied, on the one hand, with the sine value of the phase angle at the point of sampling of the alternating signal or another scanning signal with the same frequency as the alternating voltage signal, but phase-shifted against that signal and, on the other hand, with the corresponding cosine value.
