Installation instructions

4.5.1

Installation requirements/System sizing information

The CoriolisMaster FCB330, FCB350, FCH330, FCH350 is
suitable for both indoor and outdoor installations. The
standard device has an IP 67 enclosure. The flowmeter sensor
is bidirectional and can be installed in any mounting position.
It is important to ensure that the meter pipes are always
completely filled with fluid. The material resistance of all
wetted parts must be clarified.
The following points are to be considered during installation:
— The preferred flow direction is indicated by the arrow on the
flowmeter sensor. Flow in this direction will be indicated as
positive (a forward/reverse flow calibration is available as an
option).
— The presence of gas bubbles in the meter tube increases
the likelihood of erroneous measurements, particularly
when measuring density. Therefore, the sensor should not
be installed at the highest point in the system.
Advantageous are installations in low pipeline sections,
e.g., at the bottom of a U-section in the pipeline (invert).
— Make sure that any gases dissolved in the medium do not
outgas and that the meter tubes are always completely full.
To safeguard this, a minimum back pressure of 0.2 bar (2.9
psi) is recommended.
— In case of gas measurements ensure that the gases are dry
and do not contain liquids.
— Make sure that operation below the vapor pressure cannot
occur when a vacuum exists in the meter tube or when
liquids with a low boiling point are being processed.
— Ensure that during operation no Phase transitions take
place in the medium. For gaseous Media any liquid phase
must be avoided, for liquid media, any gas phase must be
avoided.
— Long drop lines downstream of the flowmeter sensor
should be avoided to prevent the meter tube from draining.
— The devices can be installed directly to or from elbows,
valves or other equipment unless no cavitation is caused.
— This Flowmeter is designed for industrial installations. As
long as electromagnetic fields in the environment of the
meter are according to "best practice" as defined in the
standards covered in our "EC-declaration of conformity", no
additonal efforts have to be taken. If electromagnetic fields
exceed usual levels, sufficient distance is to be kept.
— Check that the flowmeter sensor does not come into
contact with other objects. Do not attach the flowmeter
sensor to the enclosure.
— In principle, no special supports or dampers are required
on the device. In industrial and maritime facilities designed
as "Best Paractice " typical forces are absorbed sufficiently
by the device. This is valid for serial or parallel installation of
Coriolis meters as well, as long as the use and installation
follows the manual.
— To avoid damages to the process connections and pipes
by axial forces, supports are recommended for devices of
higher weights.
4.5.2

Inlet sections

The flowmeter sensor does not require any inlet sections.
Make sure that any valves, gates, sight glasses, etc., in the
vicinity of the flowmeter sensor do not cavitate and are not set
in vibration by the flowmeter sensor.
4.5.3

Model in remote mount design

Make sure that the flowmeter sensor and transmitter are
assigned correctly. Compatible devices have the same end
numbers, e. g., X001 and Y001 or X002 and Y002, on the
name plate.
4.5.4

Pressure loss

Pressure loss is determined by the properties of the medium
and the flow.
Documents to help you to calculate pressure loss can be
downloaded from www.abb.com/flow.
4.6

Mounting positions

The flowmeter operates in any mounting position. The ideal
installation position is vertical with flow from bottom to top.
IMPORTANT (NOTE)
EHEDG certification requires a self draining installation, only
possible with a vertical installation.
