Orifice Flanged Meter Runs

Orifice Flanged Meter Runs

Flow Measurement Excellence

Orifice Flanged Meter Runs are designed for use on many different process applications and conditions. These devices are carefully designed and manufactured to achieve optimum flow metering uncertainty, ensuring that installation of the orifice plate, adjacent pipework and tappings are compliant with ISO 5167 and AGA 3.

Orifice Flanged Meter Runs are an economical and simple design used for many
applications within the industry. Calibration and Dimensional Certificates are available
for square edge orifice plates for use in Fiscal and Allocation metering, if required.

Available designs include:

  • Square edge orifice plates
  • Conical entrance & quarter circle
  • Eccentric plates

There are a range of benefits for orifice plate designs including:
  • Process Flow Measurement of hydrocarbons, most gases and liquids
  • Allocation, custody transfer and fiscal flow metering
  • Applications with low Reynolds numbers
  • Flow measurement of viscous, dirty and contaminated fluids
  • Flow metering of fluids with suspended solids or entrained gas

Solartron ISA offer Orifice Flanged Meter Run designs to suit many different pipework configurations, lengths, orientations and end connection requirements for any flow measurement application, using proven flow metering technology to all industry standards.

We provide complete Engineering support from initial design and sizing concepts to manufactured final products.
