GM868 Specifications
Operation and Performance
Fluid Types
All acoustically conductive gases
Pipe Sizes
2 in to 120 in (50 mm to 3,000 mm) NB and larger
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
Specifications assume a fully developed flow profile
(typically 20 diameters upstream and 10 diameters
downstream of straight pipe run) and flow velocity greater
than 3 ft/s (1 m/s).
Measurement Parameters
Mass flow, standard and actual volumetric flow, totalized
flow, and flow velocity
