method and apparatus for providing temperature flow rate compensation for a coriolis flow meter . the described compensation compensates both flow calibration factor and the nominal time delay , commonly called “ zero ” in the art . after a coriolis flow meter is installed into a process , whether for calibration or for actual process use , it need only be zeroed once over its lifetime following its installation . this is a significant improvement over prior coriolis flow meters that may need to be re - zeroed after minor changes in pressure , temperature , or installation .
