V-Cone Flow Meters

Engineered for the service

Per ISO 5167-5:2022, the V-Cone reshapes flow around a centrally mounted cone, creating a stable downstream differential pressure. Metering packages are engineered for each service and require an appropriate calibration and approval route where used for custody transfer.

Key design features

Center-body flow conditioning

Compact piping layout

Stable differential-pressure signal

Engineered calibration path
