Editing Flow measurement (section)

===Coriolis flowmeters===
Using the [[Coriolis effect]] that causes a laterally vibrating tube to distort, a direct measurement of [[mass flow rate|mass flow]] can be obtained in a [[coriolis flow meter|coriolis flowmeter]].<ref>{{Cite book|title=Introductory guide to Flow Measurement|last=Baker|first=Roger C.|publisher=ASME|year=2003|isbn=0-7918-0198-5}}</ref> Furthermore, a direct measure of the density of the fluid is obtained. Coriolis measurement can be very accurate irrespective of the type of gas or liquid that is measured; the same measurement tube can be used for [[hydrogen]] gas and [[bitumen]] without re[[calibration]].{{Citation needed|date=July 2015}}

Coriolis flowmeters can be used for the measurement of natural gas flow.<ref>[[American Gas Association]] Report Number 11</ref>
