Case Study
Thermal Flow Meter Calibration for Natural Gas Service
This case study explains how inaccurate thermal flow meter calibration can create significant measurement errors when natural gas composition differs from the gas used during factory calibration. Using real-world examples from multiple regions, it demonstrates how composition changes can increase operating costs and reduce measurement accuracy. The paper recommends three practical assessments to improve performance, including verifying gas composition, updating field configurations and specifying gas composition during procurement. It also highlights technology that enables field adjustment of gas composition without factory recalibration, improving long-term accuracy and reducing lifecycle costs.
