Orifice plates for flow FPD150

The FPD150 is a range of flow measurement orifice plates, some of which are available on next day delivery if required, are available with a variety of profiles to handle a wide range of applications, from clean fluids and low viscosity liquids through to dirty fluids or high viscosity liquids.

They are usually supplied with a data tab welded to (or integral with) the circumference. On this tab can be engraved information such as the Tag Number and orifice plate bore, all of which are visible without removing the plate from the line.

Orifice flange assemblies FPD160

The ABB FPD160 is a range of flow measurement orifice plates fitted into weld-in orifice flange unions with flange tappings. The orifice plates are available with a variety of profiles to handle a wide range of applications, from clean fluids and low viscosity liquids through to dirty fluids or high viscosity liquids.

Orifice Plate designs: 

  • Concentric square-edge orifice plate for clean liquids/gases/steam
  • Quarter circle orifice plate for viscous fluids
  • Conical entrance orifice plate for viscous fluids
  • Eccentric orifice plate for dirty fluids
  • Segmental orifice plate for dirty fluids
  • Orifice plate in holder between RTJ orifice flanges

Restriction orifice plates FPD190

The FPD190 restriction plate has an orifice bore (and plate thickness) that is calculated to achieve the required restriction to the flow rate or pressure drop whilst maintaining plate integrity. A multi-restriction assembly, consisting of several plates in series, can be engineered for use where the required pressure drop cannot be achieved (or where the noise level would be too high) across a single plate.

FPD190 restriction plates and assemblies are available in a wide range of materials to suit the process conditions.
