Measuring natural gas is both a science and an art. Guidelines and industry practices explain how to accurately measure natural gas. The ‘art” comes in trying to minimize errors and prevent measurement problems. However, sometime it’s easier to explain “how not” to measure gas when reviewing measurement errors.

Measurement errors can be caused through poor installation practices, poor measurement practices, operational changes, and human error. The purpose of this paper is to address some “real life” cases of measurement errors.
