Title:
SENSOR DRIFT HANDLING IN VIRTUAL FLOW METERING
Document Type and Number:
WIPO Patent Application WO/2018/058511
Kind Code:
A1
Abstract:
The present discussion relates to the addressing sensor drift issues in virtual flow meter applications. By way of example, in certain implementations: 1) pressure, temperature, or other sensors are prioritized based on one or more evaluation criteria, 2) a determination is made as to whether there are sensor drifts for those sensors with high priority, and 3) sensor readings experiencing drift, such as above a specified or measureable threshold, are compensated. In this manner, virtual flow meter accuracy is maintained over time.
