Heat transfer based flowmeter for high temperature flow rate measurements: Design, implementation and testing

摘要

However orifice meter is considered the oldest known device for measuring or regulating the flow of liquids, gasses or slurries. Its structure consists of a plate with a drilled hole (of specified size and position). The increase that occurs in the velocity of a fluid as it passes through the hole in the plate results in a pressure drop across the plate. Recent studies on orifice meter focused on the influences of their integration (Setup) on the flows [14,15].
