SYSTEM, METHOD, AND COMPUTER PROGRAM PRODUCT FOR DETECTING A PROCESS DISTURBANCE IN A VIBRATING FLOW DEVICE
First Claim
1. A method for detecting a process disturbance generated from entrained gas or particulates within a fluid flowing in a vibrating flow device (5), comprising the steps of:
- measuring a drive gain;
determining a void fraction; and
detecting the presence of the process disturbance based upon a comparison between the measured drive gain and a drive gain threshold value and a comparison between the void fraction and a void fraction threshold value.

Abstract
The present invention relates to a system, a method, and a computer program product for detecting a process disturbance from entrained gas or particulates within a fluid flowing in a vibrating flow device (5). In one embodiment, the system, the method and the computer program may involve a comparison between a measured drive gain and a drive gain threshold value and a comparison between a void fraction and a void fraction threshold value. In another embodiment, the system, the method and the computer program may involve a comparison between a measured drive gain and a drive gain threshold value, a comparison between a void fraction and a void fraction threshold value, and a comparison between a measured mass flow rate and a nominal mass flow rate threshold value. In yet another embodiment, the system, the method and the computer program may involve a comparison between a measured drive gain and a drive gain threshold value and a comparison between a measured pick-off amplitude and a pick-off amplitude threshold value.
