Abstract
Flow meter or flow meter, comprising: a vibratable flow tube or tube;
a driver connected to the flow tube operable to impart movement to the flow tube;
a first sensor connected to a first portion of the flow tube and operable to sense a frequency of movement of the flow tube and generate a first sensor signal;
a second sensor connected to a second portion of the flow tube and operable to sense the frequency of movement of the flow tube and to generate a second sensor signal; and a controller operable to adjust the frequency sensed by the sensors based on a phase difference between the first sensor signal and the second sensor signal to thereby obtain a corrected frequency.
