DIFF Subgroup
G01P 5/02 by measuring forces exerted by the fluid on solid bodies, e.g. anemometer
Introduced: September 1968
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
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
IPC and CPC are identically structured here. All 2 subcodes exist in both systems.
1 shared codes have differing titles between IPC and CPC.
