ABSTRACT:
Method and apparatus (121) 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.
