A form of gas or liquid flowmeter consisting of a diaphragm in which there is an orifice placed transversely across a pipe, the difference in pressure on the two sides of the diaphragm is a measure of flow velocity.  4, fiche 1, Anglais, - orifice%20meter

An orifice meter is an inferential meter in which the fluid velocity and flowrate are inferred from the pressure drop occurring through the known area of an orifice plate. Specifically, orifice meter flow is calculated from the flowing gas pressure and temperature, differential pressure drop occurring across the restriction of the meter’s orifice plate, the meter geometry including the meter tube’s inside diameter and orifice plate bore, and the gas composition.  5, fiche 1, Anglais, - orifice%20meter

Les méthodes utilisées sont en évolution permanentes. On utilise toujours le système classique des débitmètres à diaphragme ou à Venturi mais parallèlement aussi des compteurs volumétriques et les compteurs à turbine.  3, fiche 1, Français, - d%C3%A9bitm%C3%A8tre%20%C3%A0%20diaphragme

Method of cones. This is a relatively simple method of measuring the mass flow, quality and enthalpy characteristics of a wet bore by using a cyclone separator and a series of measuring cones... The method avoids the separate measurement of the water(though a lip pressure discharge pipe could provide useful corroborative evidence) and enables the dryness and enthalpy of the bore mixture to be deduced indirectly. It also dispenses with the need for long straight pipes required when a sharp-edged orifice is used for the steam measurement.  1, fiche 2, Anglais, - method%20of%20cones
