A
Mass Flow Meter operating on the “Coriolis principle” contains a
vibrating tube in which a fluid flow causes changes in frequency, phase
shift or amplitude. The sensor signal is fed into the integrally mounted
pc-board. The resulting output signal is strictly proportional to the
real mass flow rate, whereas thermal mass flow meters are dependent on
the physical properties of the fluid. Coriolis mass flow measurement is
fast and very accurate.
Coriolis
mass flow meters work on the principle that the inertia created by
fluid flowing through an oscillating tube causes the tube to twist in
proportion to mass flow rate.
Many Coriolis meters have two tubes. They are made to vibrate in
opposition to each other by means of a magnetic coil. Sensors in the
form of magnet and coil assemblies are mounted on the inlet and the
outlet of both flow tubes. As the coils move through the magnetic field
created by the magnet, they create a voltage in the form of a sine wave.
These
sine waves are the key to measuring mass flow Coriolis is the most
accurate flow meter made. While many magnetic flowmeters have accuracies
in the range of 0.5 percent, many Coriolis flow meters achieve accuracy
of 0.1 percent.
It
is the high accuracy of Coriolis flowmeters that is one of the major
reasons for their extremely rapid growth over the past five years.
Companies that need flow meters for custody transfer, or want highly
accurate measurements in terms of mass, have a good reason to select
Coriolis flow meters.
The
unique Omega shaped Coriolis mass flow meter is not just shaped in this
way for the sake of differentiation from other manufacturers, and the
shape was not chosen because it was the only one not yet under patent
protection.
The
Rheonik mass flow meter is the result of intensive research work in the
early 80s when mass flow meter technology came up. Dipl.-Ing. Karl
Käppers worked on many different designs and tested them with regard to
stability, reliability, and accuracy.
