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 with the geometry calculator
1
Open the geometry calculator.
2
First select in the “Path number” field of the “Calc length, angle, diameter” tab whether
it is a 1-path or 2-path installation.
3
In the field “Sensor type” (Transducer type), select whether the device is a “Cross duct”
or “Probe” version.
4
Select “retractable” for installations with ball valve and “non retractable” for installa
-
tions without ball valve.
5
For cross-duct versions, enter the probe distance “Transducer distance” a determined
for the nozzle installation tool,
6
Enter the required dimensions:
– Circumference U
– Wall thickness w
– Gasket thickness S
– Gasket thicknesses D1 and D2
– For installation with ball valve: Length of ball valve VL
– Angle β: For cross-duct versions, enter the nominal nozzle angle (e.g. 75°, 60°,
45°). For the probe version, measure the installation angle and enter the exact
value (maximum value for measuring the installation angle: ±0,3 °).
The wL (“wetted part length”) and geometric installation parameters are calculated.
NOTICE:
The wall thickness must be determined accurately to 0.1 mm. SICK
recommends using a suitable ultrasonic measuring instrument to determine
the wall thickness.
NOTICE:
The geometric installation parameters in the “Result: Parameters for configu
-
ration” area and the wall thickness are required for configuring the measuring
system during commissioning.
