Project planning
The following Table provides an overview of the project planning work necessary as
prerequisite for trouble-free assembly and subsequent device functionality. You can use
this Table as a Checklist and check off the completed steps.
Task Requirements Work step
Determine the
measuring and
installation
location
for the device
components
Inlet and outlet paths
according to DIN EN
13284-1 (inlet at least 5x
hydraulic diameter d
h,
outlet at least 3x d
h
;
distance to stack opening at
least 5x d
h
)
For round and square ducts:
d
h
= duct diameter
– Follow specifications for new equip-
ment
– Select best possible location for exist-
ing equipment;
– For too short inlet/outlet paths: Inlet
path > outlet path
For rectangular ducts:
d
h
= 4x cross-section divided by
circumference
– Uniform flow distribution
– Representative dust dis-
tribution
Whenever possible, no deflections,
cross-section variations, feed and drain
lines, flaps or fittings in the area of the
inlet and outlet paths
If conditions cannot be ensured, define
flow profile according to DIN EN 13284-1
and select best possible location
Sender/receiver unit and
reflector fitting location
Do not fit vertically on horizontal or
slanted ducts;
max. measuring axis angle to horizontal
45 °
Select best possible location
Accessibility, accident
prevention
The device components must be easily
and safely accessible
Provide platforms or pedestals as required
Installation free of
vibrations
Acceleration < 1 g Eliminate/reduce vibrations through
suitable measures
Ambient conditions Limit values according to Technical Data If necessary:
– Provide weatherproof covers/sun pro-
tection
– Enclose or lag device components
Select the purge
air supply
Sufficient primary purge air
pressure depending on
internal duct pressure
– Up to +2 hPa, control unit with inte-
grated purge air supply
– Above +2 hPa to +30 hPa, optional
external purge air unit
Select supply type
Clean intake air Whenever possible, low amount of dust,
no oil, moisture or corrosive gases
Select best possible location for air intake
Determine required purge air hose length
Select device
components
Measuring path, duct wall
thickness with insulation
Sender/receiver unit, reflector, flange
with tube
– Select components according to Con-
figuration Table (

p. 30, §2.3 ) ;
– if necessary, plan additional measures
to fit the flange with tube (

p. 35,
§3.2.1)
Internal duct pressure Type of purge air supply
Fitting locations Cable and purge air hose lengths
Plan
calibration
openings
Access Easy and safe Provide platforms or pedestals as required
Distances to measuring
level
No mutual interference between
calibration probe and measuring system
Plan sufficient distance between
measuring and calibration level (approx.
500 mm)
Plan power
supply
Operating voltage, power
requirements
According to Technical Data (

p. 124,
§7.1)
Plan adequate cable cross-sections and
fuses
