Why these
Studies are Needed.
The accurate measurement of liquid, gas, and steam in the process industries has become more
exacting over time. There are several fundamental reasons for this trend. Users are faced with
higher product quality standards, industrial process applications have become more complex,
there is an increasing interdependence between measurement types within the more sophisticated
process information networks, and the measured fluids themselves are more precious and should
not be wasted.

Other factors that play a larger role today must also be considered. These include the current and
evolving needs of personnel safety, environmental concerns, and the expansion of process
controls to remote and often unattended locations. Clearly, the need for repeatable performance
of flow measurement devices to high standards has never been greater.
Of course, all flowmeters are calibrated to a
factory accuracy standard before they are shipped for their intended purpose in the
field. But it is precisely at this point in time that calibration questions first arise for
operators: Was the installation actually completed per manufacturer instructions in
every detail? Will the new flowmeter perform to factory specification or will the
process affect its accuracy? Will sensors
become coated by the process fluid? Will the lining be subject to wear and affect
performance? Does our flowmeter have us in full compliance with our custody transfer
contract, and how will we know when we are not?

All of these questions – and many others – lead the operator to the issues of flowmeter
calibration and recalibration. Fluid flow quantification, whether it is done volumetrically or as a
mass flow measurement, is one of the three primary industrial process control methodologies.
