Pipe Sizes
- Clamp-on transducers: 0.5 to 300 in. (12.7 mm to 7.6m)
and larger
- Wetted transducers: 1 in 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.
Clamp-On Flow Accuracy (Velocity)
- Pipe ID>,6 in (150 mm): ±1% to 2% of reading typical
- Pipe ID<,6 in (150 mm): ±2% to 5% of reading typical
Wetted Flow Accuracy (Velocity) ±1% 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 ±0.1% to 0.3% of reading
