    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&nbsp, 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&gt,6 in (150 mm): ±1% to 2% of reading typical
