Proving Coriolis Meters in Custody Transfer
Proving your Coriolis flow meters regularly is incredibly important when trying to achieve consistent accuracy and remain compliant with contracts to avoid disputes.
Micro Motion Coriolis flow meters and Small Volume Provers are quite often paired together in measuring systems these days. Micro Motion products are often chosen for the fact that they require no scheduled maintenance, they do not drift over time and the meter factors from proving remain consistent over time and as process conditions and flow rates are changing. Multiple product grades dictate that other types of meters that are not so consistent be proved for every possible set of operating conditions, and often different meter factors are needed as conditions change. Measurement systems must pass stringent repeatability requirements as outlined in the API Manual of Petroleum Measurement (MPMS), Chapter 4.8.
Micro Motion has invested in the development of specialized meter signal processing parameters to optimize the meter’s response time and signal-to-noise ratio in proving applications that have very fast run times. Prover operations can also be adjusted to average passes together such that acceptable meter factor uncertainty of ±0.027% (95% confidence) is achieved.
New best practices for proving large Coriolis meters with Small Volume Provers have been developed. To learn more about these best practices and how they can help in your custody transfer applications, register for Emerson Exchange today. This workshop will be led by Marc Buttler and is titled, Proving Best Practices for Coriolis Meters in Crude Oil Custody Transfer.
