OriMaster compact orifice flowmeter for clean liquids, gases and steam



Differential pressure flow meters

Product Brochure



StackFlowMaster is a dedicated stack gas flow measuring system based on the Torbar multi port self-averaging pitot flow meter. In most cases the probe is designed to measure across the complete diameter of the stack, but a partial-insertion option (spanning less than half the stack diameter) is available.

  • MCERTS approved
    • meets the requirements of EN 14181 & EN 15267-3
  • Manual and automatic versions
    • simple system for basic applications
    • optional meter purging (for solids contamination)
    • manual/automatic zero and span
  • Suitable for wide range of stack sizes and temperatures
    • for stacks from 1 to 8 metres (3.3 to 26.25 ft.) diameter
    • gas temperatures up to 1200 °C (2192 °F)
  • Optional end supports for larger stacks
    • flanged fitting on both sides of the stack
    • improves mechanical stability; prevents probe resonance
    • optional bayonet lock reduces risk of distortion of the probe
  • Optional partial-insertion design for larger stacks
    • lower cost / weight option for easier handling
    • usually requires pre-investigation of stack flow velocity profile
