Turbine Meters for Batching and Custody Transfer

Strengths of the turbine meter

• High turndown with ±0.5% reading accuracy over a wide range
• Very fast response for repetitive batching cycles
• Low pressure drop and small footprint for skids

Sizing for transfer duty

1. Size so the operating flow sits between 40% and 80% of the meter capacity — the sweet spot for linearity.
2. Keep at least 10D upstream straight pipe or add a honeycomb flow conditioner.
3. Match the meter to the liquid's kinematic viscosity; light hydrocarbons work best.

Proving and certification

For custody transfer, meters are flow-proved on our calibration rig and can ship with a CNAS calibration certificate. We also explain how to set the K-factor on the flow computer after verification.

Batching tips

• Use the pulse output for high-resolution counting
• Avoid air entrainment: mount so the line stays full
• Schedule recalibration every 12 months for trade metering
