CPC: using rotation of vanes (measuring speed of rotating shafts G01P3/00)

Full Title

Full titles differ between systems:

IPC:

Measuring speed of fluids, e.g. of air stream; Measuring speed of bodies relative to fluids, e.g. of ship, of aircraft > by measuring forces exerted by the fluid on solid bodies, e.g. anemometer > using rotation of vanes

CPC:

Measuring speed of fluids, e.g. of air stream; Measuring speed of bodies relative to fluids, e.g. of ship, of aircraft (application of speed-measuring devices for measuring volume of fluid G01F) > by measuring forces exerted by the fluid on solid bodies, e.g. anemometer > using rotation of vanes (measuring speed of rotating shafts G01P3/00)

Of 2 combined children, 1 exist in both systems.

1 codes are CPC-only extensions.

IPC defines codes here since 1980.
