DNV GL Initiates JIP to Investigate Accuracy of Coriolis Flow Meter Technologies

DNV GL Wednesday announced a Joint Industry Project (JIP) to assess the accuracy of Coriolis and ultrasonic flow meters for phase contaminated oil flows.

The company argues that though Coriolis and ultrasonic flow meters are widely used, there is "little validation" that they produce accurate allocation measurement results.

The JIP plans to establish testing guidelines, a performance assessment, and correction algorithms as a foundation for using Coriolis and ultrasonic flow meters for phase contaminated oil flows.

"Biases will occur in phase contaminated flows and an accepted correction algorithm is required as an important step towards qualifying Coriolis meters and ultrasonic flow meters in these situations," said Dennis van Putten, Expert Multiphase Flow Metering, DNV GL - Oil & Gas.

The testing of the flow meters is expected to occur under conditions "close to real field situations" at DNV GL's Multiphase Flow Facility in Groningen, The Netherlands.

Manufacturers of Coriolis and ultrasonic flow meters are reportedly participating in the JIP.

Bert Tinge, Senior Business Development Manager, DNV GL - Oil & Gas, said, "By being part of the project, the manufacturers will gain valuable insight into the performance of their own technology under single phase conditions contaminated with small fractions of water and gas."

The launch meeting is scheduled on June 24, 2015 at Amsterdam Airport Schiphol in The Netherlands.

Last year, Maritime and Port Authority of Singapore (MPA) announced that starting in 2017 Marine Fuel Oil (MFO) bunkering in Singapore will require the use of a mass flow metering system
