Understanding how to correctly select the right flow variable can lead to significant improvements in
process performance and cost effectiveness. Though both technologies will deliver almost identical
results under certain conditions, the deviations that can occur where a process is subject to pressure
and temperature changes makes it crucial to make the right choice from the outset.

Originally produced for the launch of ABB’s latest generation of CoriolisMaster flowmeters, the
information pack explains the fundamentals of mass and volume flow and which technique is best
suited for particular types of applications.

Titled Mass or volume? A weight off the bottom-line, the White Paper covers coriolis, thermal and
multivariable DP mass flowmeter technologies, explaining how each one works and their respective
advantages and drawbacks. The paper highlights why it can be better to measure mass or volume
flow directly, rather than expressing mass flow measurements in volumetric units, in order to eliminate
possible errors caused when factoring in standard or normalised conditions for temperature and
pressure.

These differences are further explained in the Understanding mass flow video. The video shows why
volume flow is not enough if you want to know the exact amount of a substance moving through a
pipeline and how measuring mass flow can provide qualitative and quantitative data which volume
simply cannot.

The application guide, A new generation of mass flowmeters, explains the importance of capacity,
accuracy and physical size when choosing a flowmeter and how each criteria can be met by opting for
a coriolis flowmeter. The guide also looks specifically at key applications in the oil, gas and petrochem
industries where coriolis flowmeters can be used to enable accurate control and measurement of gas
and liquid flows.

Information on other potential applications where Coriolis flowmeters can be used is contained in the
webinar presentation by David Bowers, Mass Flow Specialist at ABB. The presentation covers
various topics such as the unique way Coriolis flowmeters work through to why mass flow is the most
useful and accurate form of flow measurement. David also covers a range of case studies
demonstrating how coriolis flowmeters can be applied to a range of applications, from truck filling and
blending whiskey through to use in the lubrication of aluminium rolls.
