What meter used for liquid hydrocarbon transfer purpose?

Turbine Meter & PD Meter

Turbine meter and positive displacement (PD) meters are normally used to measure liquid hydrocarbon for custody transfer purpose.

Turbine meter has been the meter of choice for measuring liquid hydrocarbon for custody transfer and allocation purposes. Commonly used turbine meter is a twin-bladed helical turbine that has reduced sensitivity to viscosity changes than conventional multi-bladed turbine.

The meter linearity shall be within ±0.25% of average meter factor (MF) over 10:1 flow range @ specific operating viscosity.

The repeatability after 5 consecutive proving runs under stable conditions shall be within ± 0.025% of average meter factor @ each flowrate point.
