ABSTRACT:
An electronic data processing method for determining mass flow rate of media moving through a conduit under flexural vibration comprises measuring of a first value of the first electrical signal generated by a first motion sensor located at a section of the conduit, which measurement is made at an instant determined by a triggering device activated by a zero value of the second electrical signal generated by a second motion sensor located at another section of the conduit, and measuring of a second value of the first electrical signal at another instant determined by a triggering device activated by a peak value of the second electrical signal; and determining mass flow rate of the media as a function of ratio between the first and second values of the first electrical signal by using an empirically obtained mathematical relationship that includes a term cancelling out an error introduced by a delay between the cueing of the measurement of the first electrical signal by the second electrical signal and the measuring of the first electrical signal.
