Recommendations based on unlined, new pipes with water Recommended pipe or tubing sizes vary with pipe
conditions and fluid
2
PVC, CPVC, HDPE, PTFE, PDVF, stainless steel, ductile iron, aluminum, brass naval, carbon steel copper
3
Large pipe transducers are recommended for 8 to 12" pipes if normal velocity is expected to be greater than
12 ft/s (3 6 m/s)
4
Consult factory for larger pipe sizes
5
Not for metric pipes
