A flow meter is an instrument used to measure linear, nonlinear, mass or volumetric flow rate of a liquid or a gas. It measure flow using an arrangement of moving parts, either by passing isolated, known volumes of a fluid through a series of gears or chambers or by means of a spinning turbine or rotor. When choosing flow meters, one should consider such intangible factors as familiarity of plant personnel, their experience with calibration and maintenance, spare parts availability, and mean time between failure history, etc., at the particular plant site.
