GS868 Specifi cations
Operation and Performance
Fluid Types
Saturated and superheated steam
Pipe Sizes
2 in to 48 in NB (50 mm to 1200 mm DN)
Pipe Materials
All metals. Consult GE for other materials.
Flow Accuracy (Velocity)
±1% to 2% of reading typical
Accuracy depends on pipe size and whether measurement
is one-path or two-path. Accuracy to ±0.5% of reading
may be achievable with process calibration.
Repeatability
±0.2% to 0.5% of reading
Range (Bidirectional)
–150 to 150 ft/s (–46 to 46 m/s)
Rangeability (Overall)
1500:1
Specifi cations assume a fully developed fl ow profi le
(typically 20 diameters upstream and 10 diameters
downstream of straight pipe run) and fl ow velocity greater
than 3 ft/s (1 m/s).
