Orifice Carriers

Flow Measurement Excellence

The Orifice Carrier is supplied for applications where existing pipe-work has no facility for orifice tappings: when flanges are not of sufficient thickness, flanges are of composite design or pipes are lined preventing pipe taps.


Solartron ISA is able to advise the most suitable flow measurement solution for each application, using proven flow metering technology with Differential Pressure measurement covered in ISO 5167-2, ISO TR-15377, AGA3 and ASME MFC-3M. Improved metering uncertainty as the orifice flange ensures the orifice plate and orifice tappings are compliant to ISO 5167-2, ISO TR-15377, AGA3 and ASME MFC-3M.



Available designs include:
Type CA -

  • Integral Carrier
  • One piece design with the orifice tappings integral to plate
  • Easiest to install
  • Can be supplied with bolt holes for full face installation, the preferred option for GRP or similar flange materials
  • Includes an option for female grooved RTJ flanges

Type CB -
  • Split Ring Corner Tappings
  • High accuracy due to the annular chamber corner tappings
  • Orientation of tappings can be adjusted on site to aid in the installation

Type CC -
  • Split Ring Flange Tappings
  • Alternate option to orifice flanges
  • Used on By-pass lines where rodding can be required

Type RTJ -
  • Ring Type Joint Orifice Carrier
  • Design incorporates a RTJ holding ring with removable plate
  • Can be supplied as an integral if required
  • Separate components should supplied if the plate material is harder than flange material, to ensure the ring deforms and not the ring groove in the flange
  • Typically the plate holder would be the same material as the gaskets


Benefits
Solartron ISA is able to advise the most suitable flow measurement solution for each application, using proven flow metering technology with Differential Pressure measurement covered in ISO 5167-2, ISO TR-15377, AGA3 and ASME MFC-3M. Improved metering uncertainty as the orifice flange ensures the orifice plate and orifice tappings are compliant to ISO 5167-2, ISO TR-15377, AGA3 and ASME MFC-3M. These devices are low maintenance with no moving parts, and considered an economical cost effective flow measurement solution for many gas, liquid and steam applications.
