Subsea
Flow Measurement - Marcus Davis - Flow measurement in subsea
production systems, modules and templates is a challenge for flow meters. The
complexity of subsea production systems ranges from simple satellite wells with
one line to complex multiple well sites with a network of lines. Several pipe
lines join together below the surface and will eventually extend to a fixed
platform, Floating Production Storage and Offloading Vessel (FPSO), or perhaps a
pipeline running to a land-based operation. Flow measurement is required in all
phases of these operations, especially at well heads and where lines merge -Thanks

Pioneers
of Flow Measurement -Founding the Technologies of Today - Jesse
Yoder, Ph.D - It is easy to forget in today’s fast-paced world the
importance of the many thinkers and pioneers who have made modern-day
technologies possible. This is as true in the area of flow measurement as it is
in other technology segments. The following looks at some of the pioneers of
flow measurement, who formulated many of the principles that underlie the
sophisticated flow instruments of today - An excellent article from

The
Effect of Ambient Conditions on Flow Measurement - David W. Spitzer, P.E -
The entire flow measurement system should be operated within its constraints in
order to provide accurate flow measurements. This means that each component of
the flow measurement system should be considered to ensure that it is operated
properly.

Tips for flowmeter selection- The huge array of flow technology options on
offer can make selecting the correct flowmeter for an application a bewildering
task. A broad range of factors can influence flowmeter selection, of which cost
is just one. Dr Bryan Franklin, Flow Products Manager, ABB Limited recommends a
list of top tips for selecting the best all round flow system for an
application.
Let
it flow - Measuring the flow of liquids in industrial plants is critical
- In some operations, the ability to conduct accurate flow
measurements is so important it can make the difference between making a profit
and taking a loss. In other cases, inaccurate flow measurements or failure to
take measurements can cause serious or disastrous results. Includes a flowmeter
selection guide. Thanks to ISA and InTech.

Installation
and Grounding of Magmeters in Typical and Electrolytic Process Applications -
Proper installation and grounding of
magnetic flowmeters is important for accurate, reliable measurement performance.
Stray AC or DC currents through the
fluid or instrument can produce noise signals that may in turn interfere with
the relatively low flow signals
generated in today's modern pulsed DC magmeter.

Flowmeter Material Selection Guide -A
general resource for the selection of
materials for the magnetic flowmeter. One
of the advantages of the electromagnetic
flowmeter is that it is suitable for a wide
variety of applications including severely corrosive
chemicals and highly abrasive slurries. The key
to this versatility is that there is a large choice of materials
available for the electrodes and the flowtube

Your Vortex Meter Shows Zero - Liquid flow of a process fluid into a vessel
was visually confirmed. However a vortex-shedding flowmeter in the feed pipe
measured zero flow. The flowmeter was removed from service and was found to
function properly on the flow bench in the instrument shop. Which of the
following problems could cause this issue to occur? From
