Calibration and density measurement took centre stage recently in NEL’s knowledge transfer work, with consultants talking to manufacturers, end-users and metrology experts from around the world. Key events included a webinar conducted by Dr. Norman Glen and a talk given by Flow Measurement Engineer, Emmelyn Graham, at the Force Technology (re)calibration workshop in Denmark. Norman Glen’s webinar highlighted why density is such a vital aspect of flow measurement. It had over 100 attendees – the highest number to date for any NEL webinar.
“I think that we got this level of interest because of the wide importance of the topic to industry, across a wide range of sectors,” says Norman. “We got participation from academia, oil producers and manufacturers of instrumentation from around the world.”
Norman discussed the main approaches to density measurement and densitometer calibration, he also covered standards and elaborated on NEL’s work to improve density measurement.
At the Force Technology workshop, Emmelyn Graham talked about NEL’s experience with dry and wet gas calibrations, highlighting issues surrounding the calibration of Venturi tubes and Coriolis meters.
“Participants at the workshop were drawn from over 20 countries,” Emmelyn explains, “so it was a great opportunity to broaden our industry network and to let everyone know about our new Multiphase Centre of Excellence, which will provide world class testing facilities at near field conditions.”
“The workshop looked at the challenges and opportunities posed by the recalibration process from the metrological, technical, legislative and mechanical points of view,” Emmelyn adds. “There was a lot of interest in how temperature and pressure affect Coriolis meters, in manufacturers’ correction factors, in computerised meter diagnostics and in the importance of calibration standards.”
