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 Panametrics 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
