Continuous measurement of flue gas flow velocity (m/sec) using dynamic pressure measurement principle with averaging Pitot tubes

Continuous measurement of flue gas flow velocity (m/sec) using dynamic pressure measurement principle with averaging Pitot tubes

  • Unit in weatherproof glass fiber housing
  • Stainless steel probe tube 300 to 1000 mm with differential pressure transmitter and control unit in head of probe
  • Flow rate calculation (m3/sec) after entering the stack surface
  • With flue gas temperature and absolute pressure measurements
  • With optional heater for low ambient temperature and optional blow-back for dusty flue gas
Flow Velocity 3 … 30 m/s
Flow i.B. 0 … 1.000 Tm3/h
Flow i.N. 0 … 1.000 Tm3/h (1 Tm3/h = 1.000 m3/h, 1.000 Tm3/h = 1.000.000 m3/h)
Differential pressure 0 … 5 mbar
Temperature 0 … 300 / 600 °C
Absolute pressure 800 … 1.200 mbar (optional)
