McMenon's Solution

McMenon's engineered differential pressure flow measurement assemblies were supplied for the measurement of:

  • Nitrogen
  • Combustion air
  • Cooling water
  • Absorbing water

The supplied assemblies incorporated precision-machined concentric square-edged orifice plates manufactured from 316/316L stainless steel, installed within carbon steel flange assemblies designed to meet the project's pressure and installation requirements.

For gas service applications, McMenon's FPD175 Compact Orifice Carrier Assembly was selected, providing a compact solution complete with an integral three-valve manifold for simplified installation and maintenance.

For liquid service applications, FPD160 Orifice Flange Assemblies were supplied, engineered to deliver accurate, repeatable flow measurement while ensuring reliable long-term performance.
