Installation
Check the following points before installation
● Sender/receiver units to be fitted for a particular measuring point must belong to the
same system to ensure the maximum measuring precision possible. Exchanging
structurally identical sender/receiver units from different measuring systems is not
recommended.
● Sender/receiver units can only be exchanged against identical units.
● Sender/receiver units from one system are marked with sequential serial numbers
(printed on the device label).
The FLSE100-XT Master always has the lower number and the FLSE100-XT Slave the
higher number.
● The flange connections of the sender/receiver units and nozzles must be compatible.
● The flange connections of the nozzles must be free of welding beads on the inside.
4.8.1 Calculating the wetted part length wL and geometric installation parameters
Before installation, calculate how deep the sender/receiver units will be pushed into the
pipeline.
The wetted part length depends on:
● Nozzle length
● Gasket thickness
● Ball valve length
● Wall thickness
Calculating the wetted part length wL with the Geometry Calculator
Alternatively to manual calculation of the wetted part length wL, the provided calculator can
be used:
1 Open the Geometry Calculator.
2 On the "Calc length, angle, diameter" tab, first select in the "Path number" field if the
installation is a 1-path or a 2-path installation.
3 In the field "Transducer type" select if it is a "cross-duct" or the "Probe" device version.
4 Select "retractable" for installations with ball valve and "non retractable" for installations
without ball valve.
5 For cross-duct versions, enter the "Transducer distance" a determined during nozzle
installation,
p. 38, §4.7.2 .
6 Enter the required dimensions:
– Circumference U
NOTICE:
The deformation characteristic of the flange gasket has an influence on the
geometry of the installation and therefore on the uncertainty of the
measurement. SICK recommends:
● Only use the same gasket type as the original delivery.
● Apply a tightening torque according to Operating Instructions FLOWSIC100
Flare §6.7 "Sealing installation instruction".
NOTICE:
The wall thickness must be determined accurately to 0.1 mm. SICK
recommends using an ultrasonic wall thickness measuring device.
