Flow measurement range (bi-directional)
0.5 to 250 ft/s (0.15 to 76 m/s)
Turndown Ratio = 500:1
Flow measurement accuracy
• 1 Path:
• ±0.075 ft/s (±0.02 m/s) at flow range of 0.5 to 5 ft/s
(0.15 to 1.5 m/s)
±1.5% of reading at flow range of 5 to Vmax/s (1.5 to
Vmax)
• 2 Path:
±0.05 ft/s (0.015 m/s) at flow range of 0.5 to 5 ft/s
(0.15 to 1.5m/s)
±1.0% of reading at flow range of 5 to Vmax (1.5 to 76
Vmax)
Note: Accuracy/repeatability specifications assume a
final installation with fully developed flow profile (typically
20 diameters upstream and 10 diameters downstream of
straight pipe run), Reynolds Number> 5000 and single phase
fluids. Applications with piping arrangements that induce
swirl (e.g., two out-of-plane elbows) may require additional
straight run and/or flow conditioning. For shorter straight
pipe runs, consult the factory for a computational flow
dynamic evaluation.
Repeatability
±0.2% to 0.5% of reading
