Specifications
Operation and Performance
Fluid Types
Acoustically conductive fluids, including most clean
liquids, and many liquids with entrained solids or gas
bubbles. (Maximum void fraction depends on transducer,
interrogation carrier frequency, path length and pipe
configuration.)
Pipe Sizes
• Using clamp-on transducers: 0.5 to 300 in
(12.7 mm to 7.6 m) and larger
• Using wetted transducers: 1 to 200 in
(25.4 mm to 5 m) and larger
Pipe Wall Thickness
Up to 3 in (76.2 mm)
Pipe Materials
All metals and most plastics. Consult GE for concrete,
composite materials, and highly corroded or lined pipes.
Flow Accuracy (Velocity)
±0.5% of reading (achievable with process calibration)
Typical Clamp-On Flow Accuracy (Velocity)
• Pipe ID>6 in (150 mm): ±1% to 2% of reading
• Pipe ID<6 in (150 mm): ±2% to 5% of reading
Typical Wetted Flow Accuracy (Velocity)
±1% of reading
Accuracy depends on pipe size, installation and whether
measurement is one-path or two-path.
Repeatability
±0.1% to 0.3% of reading
Range (Bidirectional)
-40 to 40 ft/s (-12.2 to 12.2 m/s)
Rangeability (Overall)
400:1
Specifications assume a fully developed flow profile
(typically 10 diameters upstream and 5 diameters
downstream of straight pipe run) and flow velocity
greater than 1 ft/s (0.3 m/s).
Measurement Parameters
Volumetric flow, totalized flow and flow velocity
Electronics
Flow Measurement
Patented Correlation Transit-Time mode
