Introduced: July 1974
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 > using rotating vanes with axial admission > with mechanical coupling to the indicating device
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 > using rotating vanes with axial admission > with mechanical coupling to the indicating device
No child classifications to compare. This is a leaf node in both IPC and CPC.
