Реферат: Orifice plate for a mass flow meter in which a pressure drop across the orifice plate is measured by a pressure transducer and used to determine the mass flow rate. The orifice plate (1) comprises a disk with a circular central opening (2). An area (1.1) around the inner circumference of the disk is made of sintered metal material or a non-metallic hard material.
