This report was developed to assist designers and users in operating, calibrating, installing, maintaining and verifying Coriolis flow meters used for natural gas flow measurement. Coriolis meters infer mass flow rate by measuring tube displacement resulting from the Coriolis effect. The scope of this document is limited to the measurement of natural gas and associated hydrocarbon gases either as pure hydrocarbons, as a mixture of pure hydrocarbons, and diluents. Although not within the scope of this document, Coriolis meters are used to measure a broad range of compressible fluids (gases), other than natural gas.

This report is applies to Coriolis meters used in medium to high-pressure natural gas applications. Typical applications include measuring single-phase gas flow found in production, process, transmission, storage, distribution, and end-use fuel measurement systems.
