General installation conditions

Installation location and assembly

Note the following points when selecting the installation
location and when mounting the sensor:
• The ambient conditions (IP rating, ambient temperature
range T ) of the device must be adhered to at the
ambient
installation location.
• Sensors and transmitters must not be exposed to direct
sunlight. If necessary, provide a suitable means of sun
protection on site. The limit values for ambient
temperature T
ambient
• On flange devices, ensure that the counterflanges of the
piping are aligned plane parallel. Only install flange
devices with suitable gaskets.
• Prevent the sensor from coming into contact with other
objects.
• The device is designed for industrial applications.
No special EMC protective measures are required if the
electromagnetic fields and interference at the installation
location of the device comply with 'Best Practice' (in
accordance with the standards listed in the declaration of
conformity).
Maintain a suitable distance from electromagnetic fields
and interference that extend beyond the usual
dimensions.
Seals
Users are responsible for selecting and mounting suitable
gaskets (material, shape).
Note the following points when selecting and mounting gaskets:
• Use gaskets made from a material that is compatible
with the measuring medium and measuring medium
temperature.
• Gaskets must not extend into the flow area, since
possible turbulence may influence the accuracy of the
device.
Calculating pressure loss
Pressure loss depends on the properties of the medium and the
flow rate.
A good aid for pressure loss calculation is the Online ABB
Product Selection Assistant (PSA) for flow at
www.abb.com/flow-selector.
must be adhered to.
Brackets and supports
No special supports or damping are required for the device when
the device is used and installed as intended.
In systems designed in accordance with 'Best Practice', the
forces acting on the device are already sufficiently absorbed.
This is also true of devices installed in series or in parallel.
For heavier devices, it is advisable to use additional supports /
brackets on site. Doing this prevents damage to the process
connections and piping from lateral forces.
Please observe the following points:
• Mount two supports or brackets symmetrically in the
immediate vicinity of the process connections.
• Do not fasten any supports or brackets to the housing of
the flowmeter sensor.
Note
For increased vibration load, such as for example on ships, the
use of the 'CL1' marine design is recommended.
Inlet section
The sensor does not require any inlet section.
The devices can be installed directly before/after manifolds,
valves or other equipment, provided that no cavitation is caused
by this equipment.
Mounting position
The flowmeter operates in any mounting position.
Depending on the measuring medium (liquid or gas) and the
measuring medium temperature, certain mounting positions are
preferable to others.For this purpose, consider the following
examples.
The preferred flow direction is indicated by the arrow on the
sensor.The flow will be displayed as positive.
The specified measuring accuracy can be achieved only in the
calibrated flow direction (for forward flow calibration, this is
only in the direction of the arrow; for the optional forward flow
and reverse flow calibration, this can be in both flow directions).
