with positive-displacement meter or turbine meter to determine the volume flow

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 > Indirect mass flowmeters, e.g. measuring volume flow and density, temperature, or pressure > with positive-displacement meter or turbine meter to determine the volume flow

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 > Indirect mass flowmeters, e.g. measuring volume flow and density, temperature or pressure > with positive-displacement meter or turbine meter to determine the volume flow

No child classifications to compare. This is a leaf node in both IPC and CPC.
