Measuring system i.e. measuring device and/or Coriolis or mass flow measuring device for medium e.g. gas and/or liquid, flowing in pipeline, has transmitter electronics generating measured value

摘要

The system has transmitter electronics (TE) delivering a driver signal for oscillation exciter effecting vibrations. The transmitter electronics generate a measured value that represents an excitation power required for maintaining vibrations of a measuring tube (MT), a damping as a result of inner friction in the medium flowing in a measuring transducer of vibrations of the measuring tube and a pressure difference. The measured value represents the pressure difference occurring between two predetermined reference points in flowing medium by a primary signal application of the damping. An independent claim is also included for a method for measuring a pressure difference arising within a flowing medium.
