From Flow Measurement
|Flowmeters that measure mass directly using the properties of mass, as opposed|
to those that measure volume or velocity, were developed and commercialized in
the 1980s. Meters of this type have found wide application because the fluid measurement
is virtually independent of changing fluid parameters. Many of the other
flowmeter technologies are affected by changes in fluid density, viscosity, pressure,
and/or temperature. Meters that measure mass directly, in effect, weigh the
fluid as it passes through the meter, yielding a highly accurate measurement that is
virtually independent of varying process conditions that often occur. Because of
this unique ability, it is possible to use a mass flowmeter on a wide variety of process
fluids without need for recalibration or compensation to specific fluid parameters.

Liquids with entrained
The Coriolis principle flowmeter is a true mass flowmeter because it uses the
properties of mass to measure mass. It is relatively easy to apply and size. Because
it possesses no moving parts, it exhibits low maintenance requirements and does
not require frequent calibration. Wetted parts that can be constructed of a variety
of materials make...
