This portable liquid flowmeter measures flow from outside plastic, metal or concrete-lined pipes nonintrusively. Applicable for ultrapure to extremely dirty liquids such as raw sewage and slurries. Measurable parameters: volumetric flow, totalized flow and flow velocity.
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: 0.5 in to 300 in (12.7 mm to 7.6 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
- Range (Bidirectional): –40 to 40 ft/s (–12.2 to 12.2 m/s)
- Rangeability (Overall): 400:1
- Measurement Parameters: Volumetric flow, totalized flow and flow velocity
