The Measurement Principle
Coriolis 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.
Rheonik Coriolis Mass Flow Meter works on the principle that the inertia created by fluid flowing through an oscillating tube causes the tube to twist in proportion to the mass flow rate. Many Coriolis meters have two tubes.
They are made to vibrate in opposition to each other using 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.
The Omega product design
The Rheonik product range, due to the unique Omega loop, allows it to serve extraordinary applications. It is the central element and offers many advantages over traditional bending movements.
Among other things, it allows the use of larger tube wall thicknesses, providing better resistance to abrasion and corrosion. Furthermore, the inner parts warrant a most stable design even using the thinnest tubes of sub 1 mm diameter for very low flow applications.
The design type is the key to Rheonik’s wide and superior range of reliability and usability.
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 for stability, reliability, and accuracy. Read more.
Accuracy
Coriolis flowmeters are the most accurate flowmeters made. While many magnetic flow meter has accuracies in the range of 0.5 percent, many Coriolis flow meters achieve an 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 the Coriolis flowmeter also very easy to install
