2.1.3.5 Hybrid Single-Phase Flowmeters (Possible Combinations)
Flowmeters can be used in many possible combinations. Appropriate con-
figurations depend on the properties to be measured (velocity, density, pres-
sure drop, mass flow, and/or chemical element) and the separator design.
Falcone et al. (2014) describe three main ways to combine meters: (1)
homogenization, test measurement, and separation (techniques depending
on homogenization); (2) techniques that measure bulk flow (do not depend
on homogenization); and (3) techniques based on flow separation. The
flowmeter can be combined as described below:
• Homogenization, test measurement, and separations: Except for MPFMs,
single-property flowmeters have major issues with measurement under
