Many of these rules of thumb must be very cautiously applied. The simplifications must be clearly understood and even then have been proven to give wrong and misleading solutions. The dangers here cannot be stressed enough.

-->Raising the Bar for Primary Elements
Control Engineering Online
<<New measurement technologies are flowing through the stream measurement
marketplace. New flowmeters such as ultrasonic, vortex, and Coriolis are
causing a fundamental shift in the market away from traditional technologies
and towards the new technologies. User concerns with reliability, cost of
ownership, maintenance requirements, and improved accuracy are driving these
changes. Differential pressure (dp) flowmeters are squarely in the middle of
this change. Dp flowmeters use a primary element to place a constriction in
the flow stream, causing a drop in pressure. The device's transmitter uses
the resulting pressure drop to calculate the flow rate. Flow rate is
proportional to the square root of the difference in pressure, and is
calculated using Bernoulli's equation.>>

<<Selecting the right flowmeter, and even more importantly, installing it
correctly, are critical for the proper operation of the building automation
system (bas). Flowmeters that are not selected correctly or that are not
installed correctly can produce large errors and cause a great deal of
trouble. The first step in selecting the right flowmeter for the application
is to compare the flowmeter specifications with the actual application. You
have to look at the specific piping, pressure, and temperature conditions,
and make sure that the flowmeter is going to be operating in the optimum
portion of its measurement and operating range.>>

<<The V-Cone's remarkable performance characteristics, however, are the
result of its unique design. It features a centrally-located cone inside the
tube. The cone interacts with the fluid flow, reshaping the fluid's velocity
profile and creating a region of lower pressure immediately downstream of
itself. The pressure difference, exhibited between the static line pressure
and the low pressure created downstream of the cone, can be measured via two
pressure sensing taps. One tap is placed slightly upstream of the cone, the
other is located in the downstream face of the cone itself. The pressure
difference can then be incorporated into a derivation of the Bernoulli
equation to determine the fluid flow rate. The cone's central position in
the line optimizes the velocity profile of the flow at the point of
measurement, assuring highly accurate, reliable flow measurement regardless
of the condition of the flow upstream of the meter.>>

<<Doppler and transit-time flowmeters are gaining ground in liquid, and in
some instances gas, flow measurement applications. Understanding how they
work will help guarantee optimum performance.>>
