The measurement of flow has received much interest over the years by engineers, researchers, and scientists. Flowmeters, sensors, and instrumentation have been developed for measuring just about any kind of flow under any condition, including gases, vapors, liquids, solids, two-phase flow, and even three-phase flow. The selection of an appropriate flowmeter or sensor is both an art and a science. This article is a review of some of the more common flow measurement methods, their applications, advantages, and disadvantages. Additionally, some causes of measurement uncertainty as well as some calibration techniques are discussed. Most of the measurement methods covered are for closed-pipe flow, with a brief discussion concerning open-channel flow. The flow of solids and multiphase flow are not discussed.
