Abstract
A flow measuring system of the Coriolis type for measuring a mass flow, with a flow tube and with excitation elements for causing the flow tube to rotate about an axis of rotation, with at least three sensors arranged free of the flow tube for generating analog signals that correspond to the movement of the tube, and with elements for digitizing the analog signals and for computing the mass flow from the digitized sensor signals. The computation elements are arranged for using exclusively the time information from the sensor signals. The accurate time information of the sensors is used by algorithms in digital electronic circuits for accurately determining the ratio between amplitudes due to excitation and those due to Coriolis forces. The mass flow is derived from this ratio.
