Coriolis flow meter
A U-tube or curved bent pipe with the inlet and outlet returning to the same plane. Coriolis meters report mass flow directly, plus density and temperature as secondary variables.

How it’s drawn.
A curved or U-shaped tube returning to the line, marking a meter that reports mass flow directly. Because it measures mass, it often carries density and temperature as secondary readings, so its tag can be multivariable. It appears where the mass charged or transferred matters more than the volume rate.
Typical usage.
Custody-transfer metering, batch operations where total mass charged matters more than rate, polymer process and any service where density-corrected mass flow is the target. Multivariable U-prefix tagging is increasingly common.
Telling it apart.
- A Coriolis meter reports mass flow directly, not volume. That is the reason it is chosen for custody transfer and batching.
- Its curved-tube symbol is distinct from the straight inline body of a magnetic meter.
- A multivariable tag reflects that one meter reports several variables, not several separate instruments.
