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
- 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
Measuring range
