FOWTECHmake ORIFICE FLANGE ASSEMBLIES are used for measuring flow of various Liquids, Gases & Steam from

1 ½”to 24” line sizes. It gives an acceptable level of uncertainties at lowest cost and long life without regular maintenances. Orifice Plates are most commonly used as primary element for flow measurement in pipelines based upon the principle of measurement of ‘Differential Pressure’ created when an obstruction is placed in the fluid flow, due to increase in fluid velocity.
