Abstract: The use of error analysis as applied to measurement systems is not common in the gas industry. The accuracy of displacement and rate of flow meters used for gas measurement are usually quoted as a definite value. Note that rarely are such statistical measures as average error, median error, mode and range of errors based on the standard deviation ever heard. Of course the main reason for this is that the measurement conditions, equipment, and their resulting accuracy are usually the result of a mutual agreement between buyer and seller. Thus, the contract measurement system tends to be thought of in terms of an error free status, especially with the passage of time.
