flow measurement The hydrogen atoms respond to the pulses and send back echoes which are recorded. A multiphase flow meter is a device used to measure the individual phase flow rates of constituent phases in a given flow (for example in oil and gas industry) where oil, water and gas mixtures are initially co-mingled together during the oil production processes.
