by measuring pressure or differential pressure

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 > by measuring pressure or differential pressure

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 measuring pressure or differential pressure

IPC and CPC are identically structured here. All 3 subcodes exist in both systems.

IPC defines codes here since 1974.
