Coupling arrangements to the indicating device

Introduced: January 1980

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 differences of pressure in the fluid > using Pitot tubes > Coupling arrangements to the indicating device

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 differences of pressure in the fluid > using Pitot tubes > Coupling arrangements to the indicating device

IPC and CPC are identically structured here. All 1 subcodes exist in both systems.

1 shared codes have differing titles between IPC and CPC.

IPC defines codes here since 1980.
