first meeting of the Flow Recalibration Working Group (FRWG) was held at the
North American Custody Transfer Measurement Conference in San Antonio, Texas on
June 23, 2016. In attendance were representatives of some of the leading
flowmeter manufacturers, along with members from some of the leading flow
calibration facilities worldwide, including CEESI and NMi Euroloop. Several more
companies joined the FRWG at the Conference. For a statement of purpose and list
of members, go to www.frwg.org.
idea for the FRWG arose out of three visits I made to the Middle East in 2009,
interviewing onsite a number of oil and gas companies such as Oman Gas and Saudi
Aramco (15 in all). All these companies use flowmeters for custody transfer
measurement. Mostly they use ultrasonic and turbine meters for this purpose.
They expressed a desire for guidance in determining when their flomweters need
to be recalibrated, since there is no generally accepted industry standard to
determine when a flowmeter needs recalibration. They asked me if I could help. I
began forming the FRWG about a year ago.
initial efforts of the FRWG will be to assemble a body of knowledge on the
subject of flowmeter recalibration by assembling existing knowledge in the form
of papers and accounts of experiences on this subject. We also plan to do a
survey of end-users in multiple industries to ask for their input and experience
on this subject. Our initial focus will most likely be in the oil and gas
industry. We also plan to contact multiple calibration facilities around the
world for their input.
is an industry wide effort that has the support and participation of many of the
leading flowmeter manufacturers and flow calibration facilities. We would like
to hear from others in the industry with experience in this area. We would like
to arrive at a list of criteria that end-users can employ to determine whether
their flowmeter needs to be recalibrated. This is likely to vary by flowmeter
type, and also by whether the meter is measuring liquid, gas, or steam. The list
of criteria may include diagnostic software, using a check meter, running tests
on component parts, having an onsite calibration, and other options. How do you
decide whether your flowmeter needs to be recalibrated? Please let us know.

so they can be considered by the FRWG as a whole. Thank you!
