DF 252 Gas flow velocity and flow rate measurement

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

Basic-Equipment
  • 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
