3.1 Project Planning
The following table provides an overview of the project planning work you have to carry out
to ensure that the device is correctly installed and fully functional. You can use this table as
a checklist by ticking off all the steps you have carried out.
Task Requirements Step
Determine
the
measuring
and
installation
locations for
the device
components
(see Section
3.1.1)
• Inlet and outlet sec-
tions must be of suf-
ficient length
• Homogeneous flow
distribution
If possible, no bends, cross-section variations,
feed pipes, discharge pipes, flaps, or fittings in the
inlet and outlet sections.
Comply with specifications for new
installations; choose the best possible
location for existing installations; if
necessary, determine flow profile
according to DIN EN 132841;
if the inlet/outlet sections too short:
inlet section > outlet section
Accessibility, accident
prevention
The device components must be easily and safely
accessible
Provide platforms if necessary
Vibration-free
installation
Accelerations < 1 g Take appropriate measures
to eliminate/reduce vibrations
Ambient conditions For limit values, see "Technical data". If necessary:
• Fit weatherproof covers/sun protec-
tion
• Cover or insulate device components
Purge-air supply (for
purged FLSE100 only)
Clean intake air (as little dust as possible, no oil,
humidity, corrosive gases)
Choose the best possible intake loca-
tion
Choose the
device
components
Internal duct diameter Type of sender/receiver unit Choose the components according to
the configuration table and notes in
Section 2.3;
If necessary, plan additional measures
to install the flange with pipe
(see Section 3.2.1).
Duct wall strength with
insulation
Nominal length of sender/receiver unit, flange
with pipe
Internal duct pressure Type of sender/receiver unit and purge-air unit
(for purged FLSE100)
Gas temperature • Type of sender/receiver unit (standard or inter-
nally cooled)
• Purge-air supply for purged FLSE100
Dust concentration Type of sender/receiver unit
Gas condition Material of duct probe and transducer
Installation locations Cable and purge-air hose lengths
Plan the
calibration
openings
Accessibility Easy and safe Provide platforms/pedestals if
necessary
Distances to the
measurement level
No mutual interference between calibration probe
and FLOWSIC100
Ensure sufficient distance between
the measurement and calibration level
(approx. 500 mm)
Plan the
power supply
Operating voltage,
maximum demand
According to the technical data in Section 2.6 Ensure sufficient cable cross-sections
and fuse
