Dean Standiford, Flow Metrology Scientist at Dutch National Metrology Institute VSL, explains in the August 2021 issue of LNG Industry magazine how insulating a flowmeter can affect the flowmeter temperature measurement value and how this can affect the mass flow output, with significant implications for LNG use and trade.
As the transition to clean energy continues to drive the demand for LNG into new markets, it makes good business sense to utilise new measurement methods, such as inline dynamic mass flow measurement to improve measurement accuracy during trade. However, cryogenic temperatures are much different than water temperatures used for most
flowmeter calibrations, and a good understanding is required of all the influencing factors that are present.
The new mid scale LNG calibration facility, with its low mass flow uncertainty, enables VSL to perform SI-traceable calibrations on cryogenic flowmeters that match the end user’s process conditions. This leads to a better understanding of the cryogenic influence factors and an improved measurement accuracy in their installation.
