Title:
FLUID PROCESS CONTROL
Document Type and Number:
WIPO Patent Application WO/2010/027939
Kind Code:
A3
Abstract:
A fluid regulator characterization system 100,212 can characterize the flow of a fluid regulator 108 that results in response to a received control signal. The fluid regulator characterization system can use the characterization to achieve a linear fluid regulator flow gain over a full operating range (e.g., zero percent travel to one hundred percent travel) for the fluid regulator relative to the received control signal. A linear fluid regulator flow gain can improve process control and reduce process variability.
