Orifice plates are common differential producer type flow elements for the measurement of liquids, gases and steam flow. Orifice plates are used for measuring and controlling fluid flow and can also be used to reduce pressure in a pipe system. The concentric, square edge type of orifice plate is the most frequently used, offering low cost, accuracy, ease of installation and rapid availability.
