DIFF Subgroup
G01F 1/76 Devices for measuring mass flow of a fluid or a fluent solid material
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 > Devices for measuring mass flow of a fluid or a fluent solid material
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) > Devices for measuring mass flow of a fluid or a fluent solid material
IPC and CPC are identically structured here. All 2 subcodes exist in both systems.
1 shared codes have differing titles between IPC and CPC.
IPC defines codes here since 1974.
