Introduced: January 2000
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 the direct influence of the streaming fluid on the properties of a detecting acoustical wave
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 the direct influence of the streaming fluid on the properties of a detecting acoustical wave
Of 2 combined children, 0 exist in both systems.
