Jet Deflection Flowmeters

Jet deflection flowmeters are used in gas and vapor services at 0-30 m/s velocity in up to 2 m (6.6 ft) diameter ducts. Their error is about 2% FS, their rangeability is about 20 1, and they are suitable for operating at temperatures up to 650°C (1200°F) and pressures up to 0.7 bar (10 psi). 

Jet deflection flow detectors can be considered for flow measurement in large, low-pressure, circular, or rectangular ducts. If they are used in stacks
