Patent ID: 7194368

Claim:
Meter electronics ( 120 ) for a flow measurement apparatus having a processing system for correcting flow information generated by said flow measurement apparatus; said meter electronics ( 120 ) comprising: instructions for directing said processing system to: sample a signal representing flow information generated by said flow measurement apparatus during a zero flow state of said flow measurement apparatus to define a plurality of data points representing said signal; establish deviation limits for at least one of said data points; determine whether each sampled data point is within said deviation limits; sample a data point within said deviation limits to define spurious flow information for said zero flow state; sample a data point outside of said deviation limits to define information representing a true material flow of said flow measurement apparatus; continue said sampling of said data points as long as said sampled data points are within said deviation limits; prevent said spurious flow information from being applied as to an output of said flow measurement apparatus during the sampling of data points within deviation limits; determine that the most recently sampled data point is outside of said deviation limits and thereby represents information for a true material flow of said flow measurement apparatus; and generate an output signal representing said true material flow information represented by said most recently sampled data point.
