Orifice plate with flat sealing face and corner taps

  • Separate type, with carrier ring and optional shut-off valve
  • Size: DN50…600; up to PN100
  • Temperature: up to +400°C / +752°F
  • Material: 1.4404 / 316L



The OPTIBAR OP 3100 is an integral orifice plate (OP) with carrier ring and corner taps for flow measurement of aggressive and non-aggressive gases, steam and liquids. The carrier ring of the orifice plate is made from a solid one piece. The orifice plate is one piece with the carrier ring for smaller diameters and screwed for bigger diameters. The separate type OP can be installed between standard pipe flanges on horizontal or vertical pipes.
