Installation instructions

4.5.1

Installation requirements/System sizing information

The CoriolisMaster FCB330, FCB350 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).
— Long drop lines downstream of the flowmeter sensor
should be avoided to prevent the meter tube from draining.
— Once the flowmeter has been installed, check that it is not
subject to mechanical tension.
— Check that the flowmeter sensor does not come into
contact with other objects. Do not attach the flowmeter
sensor to the enclosure.
— 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.
— Do not install the flowmeter sensor in the vicinity of strong
electromagnetic fields (e.g., pumps, motors, transformers,
etc.).
— Make sure that there is no risk of cross talk between
multiple flowmeter sensors. To prevent cross talk, the
flowmeter sensors should be spaced distant from one other
or the pipelines between them should be decoupled.
— Request information about special installation conditions for
meter size "L".

Supports

In order to support the weight of the flowmeter sensor and to
ensure reliable measurements when adverse external effects
exist (gas bubbles in the medium, for example), the flowmeter
sensor should be installed in a rigid pipeline.
Two supports or hangers should be installed symmetrically
and with zero tension in the direct vicinity of the process
connections.
4.5.3

Shut-off devices

To conduct a system zero adjustment, shut-off devices are
required in the pipeline:
— In horizontal installations at the outlet side
— In vertical installations at the inlet side
If possible, shut-off devices should be installed both upstream
and downstream of the sensor.
4.5.4

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.
4.5.5

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.
4.5.6

Pressure loss

Pressure loss is determined by the properties of the medium
and the flow.
