Coriolis Meters in Two and Three Phases - Project Proposal

Coriolis meter testing project partners wanted

TÜV SÜD National Engineering Laboratory is looking for project partners for a groundbreaking new project to understand the accuracy of Coriolis technology when used in two and three phase flows. In recent years, Coriolis technology has been pushed beyond its traditional uses into two and three phase flows. However, the performance of meters used under these very challenging conditions have very little independent validation and end users have no way to substantiate the stated performance in both flowrate and density measurements. Independent validation is important for industry to make informed decisions about the use of Coriolis technology in two and three phase flows. For example, how does the presence of gas affect the water cut measurement in separator outlets?

The project has the objective of quantifying the performance of Coriolis flow meters in two and three phase flow conditions and will use TÜV SÜD National Engineering Laboratory’s Advanced Multiphase Facility (AMF). This is a revolutionary high-pressure, high-flow rate multiphase facility with a test range beyond anything currently available in the world.

Following feedback from expressions of interest, the target areas will be focused on liquid continuous flows with various quantities of water liquid ratio (WLR) and small quantities of gas volume fraction (GVF). However, any ranges will be covered by these tests if that is what the sponsor requires. The meter nominal size will be between 2 inch and 4 inch.

The project has been deliberately set up to accommodate small packages of bespoke work but also to include a collaborative approach. Sponsors of the project can keep test results confidential or share with other sponsors in return for their test results. In this way a single sponsor who completes the work could receive all other tests making this a very valuable test programme.

This flexible approach aims to keep the cost low for individual companies but also means work can start without having to wait for a large number of sponsors to join. Sponsors for the programme of work will continue until January 2026 with all new test work and reports completed shared with previous sponsors (if allowed). The output of each tranche of work will be a written report detailing the performance of the meter under test.

The test data can also be analysed by TÜV SÜD National Engineering Laboratory’s Digital Services team with standard data science models applied to the test results. These methods will utilise the meter under test and reference facility flow data as well as the many diagnostic parameters and will be used with specific objectives in mind. Those objectives will be specifically set by the sponsor and could include detection of second phase, correction methods or any other indicator deemed useful to the end user. This work will be an additional work package outside the standard testing costs but will produce a separate written report.

Sponsors could loan specific meters for the test work also. The project will be as flexible as possible to make the testing and reporting as beneficial as possible to the sponsors.

WHY BECOME A SPONSOR?

Sponsors will receive the following deliverables for joining the project:

• Written test report of their meter of choice under operating conditions of their choice
• All meter under test data and reference data of the tests
• Independent and unbiased testing
• Quantified measurement uncertainty estimates
• Additional meter test reports from other sponsors if chosen to share results

If you decide to add on the option to apply data science analysis, you will receive the following deliverables:

• Written report detailing the outputs
• Analysis of test results using state of the art methods
• A targeted approach to deliver the specific objective
