Installation FLSE100-XT
5.6.4
Installation sequence
Carry out all assembly work on-site.
This includes:
▸ Determining the nozzle position
▸ Welding the nozzle on
The nozzles are manufactured precisely at the factory according to customer
specifications for fitting on the pipeline.
▸ For retractable installation:
Fitting the ball valves (measuring system without optional spool piece)
▸ Fitting the sender/receiver units
5.6.5 Geometry calculator
Certain geometric parameters must be determined and calculated for installation of
FLSE100-XT sender/receiver units.
The following dimensions can be calculated using the geometry calculator:
● Probe offset a (nozzle offset),  p. 54, §5.6.7.2 .
The following parameters must be determined during installation for calculation of the
probe offset:
– Circumference and nominal nozzle angle
● Wetted part length wL,  p. 65, §5.6.8.1.
For installation of the sender/receiver units, the wetted part length is calculated from:
– Circumference
– Wall thickness
– Gasket thickness
– Nozzle length
– For retractable installation: Ball valve length
– Nozzle angle
– Additionally for cross-duct versions: Probe offset a
● Gemometric installation parameters for commissioning the measuring system,
 p. 65, §5.6.8.1.
NOTICE:
To ensure measurement accuracy, the geometric parameters must be
determined as exactly as possible. Maximum tolerances:
– Nozzle positions and fitting angle of the nozzles: ±1 mm / ±1 °
– Measurement of nozzle length: ±1 mm
– Measurement of ball valves: ±1 mm
NOTICE:
The exact wall thickness must be determined for precise calculation of the
pipeline inner diameter. “Schedule” information from the applicable standards
is less accurate than an exact measurement.
The wall thickness must be determined accurately to 0.1 mm. SICK
recommends using a suitable ultrasonic measuring instrument to determine
the wall thickness.
The geometry calculator for installation of the FLSE100-XT sender/receiver
units is available on the delivered product CD (Geometry calculator for “Flare-
XT”).
