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.
