DETERMINING A ZERO OFFSET OF A VIBRATORY METER AT A PROCESS CONDITION

摘要

A method of determining a zero offset of a vibratory meter at a process condition is provided. The method includes measuring a flow rate of a material in the vibratory meter, determining if the measured flow rate is less than a low flow threshold, measuring one or more operational parameters of the vibratory meter, determining if the one or more measured operational parameters of the vibratory meter are within a corresponding range, and if the measured flow rate is less than the low flow threshold and if the one or more measured operational parameters of the vibratory meter are within the corresponding range, then determining a zero offset of the vibratory meter based on the measured flow rate.
