Coriolis Mass Flowmeter Rheonik Germany

Overview

Rheonik was founded in 1986 with the sole purpose of developing the Rheonik Coriolis Mass Flowmeter range. After exhaustive testing of many different configurations, the unique design of the Omega tube meter with torsion rods and mass bars came into being and was granted a patent. E.g., unlike other Coriolis meters, the Omega tube design of Rheonik Coriolis meters has solutions for operation up to 1722 bar (24,969 psi) line pressure at a precision of 0,05 % and with renowned mechanical reliability.

Industrial production uses a variety of complex measurement devices to monitor and control the manufacturing and quality of goods and materials. Rheonik therefore offers a wide range of high-precision mass flow meters from 0.001 kg/min to 30,000 kg/min.

For over 35 years, we have made it our mission to empower industry partners and enable them to make their processes more efficient, thus saving costs and resources.

We are 100% focused on perfecting Coriolis mass flowmeters. And because we invest all our engineering skills in this technology day in and day out, we are good at it. This has allowed us to pioneer in many areas, such as hydrogen, high-pressure devices, or special materials.

We guarantee our international customers and partners maximum flexibility, so all our measuring instruments are custom-made at our production site in Germany. This enables us, for example, to deliver just about any connection with our devices.\

Description

Rheonik 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. Rheonik 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.

Rheonik Omega design permits increased tube wall thickness for high-pressure and higher-temperature applications. The higher wall thickness also provides long-term stability and a safety margin against potential abrasion and corrosion.

The Measurement Principle

Each mass flow meter has two measuring tubes. The oscillating system is driven by two controlled electromagnetic excitation coils. As liquids or gases flow through the oscillating omega tubes, the Coriolis force is created and causes a slight deflection of the two measuring tubes from their original shape.

The opposing tubes are referenced to each other and the changes in deflection are proportional to the mass flow rate. In practice, the referencing is done by attaching small pickup coils that generate sinusoidal voltages. The degree of deviation of the phase shift is directly proportional to the mass flow.

The Rheonik Coriolis flow meters 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 flow meter also very easy to install.  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 concerning stability, reliability, and accuracy. Read more.
