Oil and gas operators have been using Coriolis meters
for many years in well testing and production applications, but their use as
a custody transfer meter has been limited by the lack of an API Standard.
The advantages of using a Coriolis meter in petroleum applications include:
- High accuracy and turndown
- No moving parts to wear out and replace
- On-line density measurement
- Meter Factors don’t shift with changing viscosity
and density
Plus, Micro Motion’s exclusive MVD technology offers
flow-weighted temperature and density averaging, which provides additional
information for petroleum quality and quantity determinations for custody
transfers.
Micro Motion has worked closely with API for the last
several years to develop Chapter 5.6, and has had a representative on the
Coriolis Working Group for some time. With Measurement of Liquid
Hydrocarbons by Coriolis Meters part of the MPMS, oil and gas operators
can now use Micro Motion flowmeters and the new Standard to simplify and
reduce the cost of transferring petroleum.
API’s Chapter 5.6 Measurement of Liquid
Hydrocarbons by Coriolis Meters covers crude oil, hydrocarbon products
and “dense phase” fluids like LPG, NGL, and LNG. The standard includes:
- Installation and operating recommendations
- Proving procedures
- Proving report forms
