Full Title

Full titles differ between systems:

IPC:

Measuring the volume flow or mass flow of fluid or fluent solid material wherein the fluid passes through a meter in a continuous flow > by using mechanical effects > by detection of dynamic effects of the flow > using swirl flowmeters

CPC:

Measuring the volume flow or mass flow of fluid or fluent solid material wherein the fluid passes through a meter in a continuous flow (measuring a proportion of the volume flow G01F5/00) > by using mechanical effects > by detection of dynamic effects of the flow > using swirl flowmeters

CPC subdivides this area 4x more granularly than IPC with 3 additional codes.

3 codes are CPC-only extensions.

IPC defines codes here since 2022.
