Intended use

This device is intended for the following uses:

• To convey liquids and gases (including unstable measuring
media).

• To meter mass flow directly.

• To meter volumetric flow (indirectly via mass flow and
density).

• To measure the density of the measuring medium.

• To measure the temperature of the measuring medium.

The device has been designed for use exclusively within the
technical limit values indicated on the identification plate and in
the data sheets.

When using measuring media, the following points must be
observed:

• Measuring media may only be used if, based on the state

of the art or the operating experience of the user, it can
be assured that the chemical and physical properties
necessary for operational security of the materials of the
wetted parts of the temperature sensor will not be
adversely affected during the operating time.

• Media containing chloride in particular can cause

corrosion damage to stainless steels which, although not
visible externally, can damage wetted parts beyond repair
and lead to the measuring medium escaping. It is the
operator's responsibility to check the suitability of these
materials for the respective application.

• Measuring media with unknown properties or abrasive

measuring media may only be used if the operator is able
to perform regular and suitable tests to ensure the safe
condition of the device

Improper use

The following are considered to be instances of especially
improper use of the device:

• Operation as a flexible compensating adapter in piping,

for example for compensating pipe offsets, pipe
vibrations, pipe expansions, etc.

• For use as a climbing aid, for example for mounting

purposes.

• For use as a bracket for external loads, for example as a

support for piping, etc.

• Material application, for example by painting over the

housing, name plate or welding/soldering on parts.

• Material removal, for example by spot drilling the

housing.

3 Design and function

General

The ABB CoriolisMaster operates according to the Coriolis
principle.
The construction features conventional parallel meter tubes and
is characterized in particular by its space-saving, sturdy design,
wide range of nominal diameters and minimal pressure loss.

Measuring principle

If mass flows through a vibrating pipe, Coriolis forces are
generated which bend or twist the pipe. These very small
measurement pipe deformations are picked up by optimally
mounted sensors and electronically evaluated. Because the
measured phase shift of the sensor signals is proportional to the
mass flow, the mass conveyed by the measuring device can be
recorded directly using the Coriolis mass flowmeter. The
metering principle is independent of the density, temperature,
viscosity, pressure and conductivity of the fluid.
The meter tubes always vibrate at resonance. This arising
resonant frequency is a function of the meter tube geometry, the
characteristics of the materials and the mass of the medium in
the resonating meter tube. It provides an accurate measure of
the density of the measuring medium.
An integrated temperature sensor records the measuring
medium temperature and is utilized for corrections to
temperature-dependent device parameters. In summary, it is
possible to simultaneously measure mass flow, density and
temperature with the Coriolis Mass Flowmeter. Other
measurement values can be derived from these values, e.g.
volume flow rate or concentration.
