G01F1/716 - CPC Classification

Classification description:

Measuring the volume flow or mass flow of fluid or fluent solid material wherein the fluid passes through a meter in a continuous flow using marked regions or existing inhomogeneities within the fluid stream, e.g. statistically occurring variations in a fluid parameter; Measuring the time taken to traverse a fixed distance using electron paramagnetic resonance [EPR] or nuclear magnetic resonance [NMR]
