FRWG is Conducting a Flowmeter Recalibration Survey: Your Input is Needed!

Please take our flowmeter recalibration survey!  FRWG is conducting a survey of decision-makers who need to determine when to have their flowmeters recalibrated.  We need your input!  Our goal is to determine criteria to determine when flowmeters of different types need to be recalibrated.  We will then work to have these criteria adopted as an industry standard.  

Our first step is to find out what people are doing now, including how often and why they have their flowmeters recalibrated.  Our scope is worldwide, as we believe that similar considerations apply regardless of region.  So far as we know, this is the first attempt by any group to establish such a standard.

You can participate by filling out the following survey:  If you do, we will send you more information on our ongoing activities, and on how you can become more involved.  For your convenience, we have posted both a WORD and a PDF version of the survey.

Please return your completed survey to jesse@flowresearch.com, or to the address on the back of the survey form.  Thank you for your participation!

See below for a list of FRWG members and a history of the organization, including how and why it was formed.

Second Meeting for FRWG held on June 21, 2017

We held our second meeting of the Flow Recalibration Working Group (FRWG) at the CEESI North American Custody Transfer Conference in San Antonio, Texas that was held from June 19-21, 2017. We met on June 21 at the conclusion of the conference. 

The main focus of this meeting was the end-user survey that we decided to conduct at our initial meeting.  Flow Research has created a draft of the end-user survey that has been circulated to working group members At this meeting we agreed to finalize the end-user survey, and then begin to administer it.  Members agreed to provide the names of 5-10 end-users who could potentially complete the survey.

The subject of providing funding for our efforts was discussed, but we agreed to wait until completing the end-user survey to pursue this idea.

We aim to get the end-user survey underway at the beginning of 2018.  Flow Research will be circulating the draft survey towards the end of 2017 so that we can begin the survey early in 2018.  Our hope is to have some solid results by the time of our third meeting at the CEESI Custody Transfer conference in June 2018.

In the meantime, we have had some new members join our working group.  The list of FRWG members appears below.  I would especially like to welcome Pankaj Gupta (Gail), Tom Ballard (Circor), Tom Stonehouse (Baker Hughes-GE), and Aguko Willis (Kenya Bureau of Standards). Our Working Group has a truly international reach.


Flow Recalibration Working Group (FRWG)

The purpose of this group is to arrive at a group of criteria that end-users can employ to determine if their flowmeters need to be recalibrated.  This does not necessarily equate to a specific time interval.  Instead, the goal is to have some tests, programs, or criteria that can be run to determine when a flowmeter needs to be recalibrated. 

The idea for this group came out of a series of in-person interviews Flow Research did with end-users of flowmeters in the Middle East in 2009.  We interviewed 15 companies from Oman, Saudi Arabia, Qatar, and the UAE about their use of flowmeters.  Many of them expressed frustration that there was no generally agreed upon interval when their ultrasonic flowmeters need to be recalibrated.  There was also the fact that at that time there was no recalibration facility in the Middle East .  These people asked us if we could help them arrive at a standard.  I (Jesse Yoder) said that I would do what I could.

Since that time I have spoken to the AGA, which seems to have no interest in taking on this subject.  One positive development is that Emerson Process has built a flow calibration facility in Abu Dhabi, but it is currently limited to four inch liquid recalibrations.  Some countries have instituted their own rules about calibration frequency, but these periods vary and seem to differ on a country by country basis.

The series of six studies that Flow Research did in 2012 on gas flow measurement grew out of the Middle East interviews. Since then we have completed a new edition of this series. Flow Research has also completed a study of flow calibration facilities.  We have identified 147 such facilities worldwide, and have published two studies that describe these facilities and their capabilities.  One study is on liquid recalibration and one is on recalibration of gas flowmeters.  You can find a description of these studies at www.flowcalibration.org.

This Working Group is strictly a volunteer effort, and so far has no official sanction.  However, our hope is that if we do succeed in coming up with a usable set of recalibration guidelines, we can approach some of the organizations like AGA and API for approval of the guidelines.  Short of this, we can publish our report and circulate it among interested manufacturers and end-users.  Since no one has to our knowledge attempted this before, we think the results will be met with quite a lot of interest.

So far, the following people have volunteered to be on this committee:

Steve Stewart (Oil & Gas Process Solutions) (Steve.stewart@flowmd.com)  

Tom Stonehouse (Baker Hughes, a GE Compny) (thomas.stonehouse@bhge.com)

Eric van Doorn (ODS Metering Systems BV) (Eric.vandoorn@kloeckner.com)

Aguko Willis (Kenya Bureau of Standards) (agukow@kebs.org

The first task of the committee is to formulate criteria for determining when an inline multipath ultrasonic custody transfer needs to be recalibrated.  This included running a software program, using a check meter, running diagnostics, doing dry calibration, or any other method that may be effective.  We then plan to address other types of ultrasonic flowmeters, as well as other flowmeter types such as turbine, differential pressure with different primary elements, vortex, magnetic, and thermal.
