Daniel Master Meter ProverAccuracy of fiscal transfer measurement is of great importance as even a small error in measurement can lead to a large financial difference. Provers ensure a fiscal transfer system is providing the most accurate measurement possible. They provide a stationary or mobile means to facilitate calibration of flow meters before, during or after a transfer.

A prover is an automated system that provides on-site calibration. It ensures flow meters in service for fiscal and custody transfer applications maintain sustainable measurement performance as well as remain in compliance with industry standards.

The prover is placed in series with the meter to determine the meter factor during stable operating conditions. This process, known as in-situ proving, is preferable over off-site calibration because it verifies the meter’s performance using the exact product and process conditions that the meter normally experiences during field operation.

Daniel Master Meter Prover Minimize Downtime, Maximize Certainty

  • Prove a wide range of meter technologies and sizes to their factory or industry specifications.
