Determining the nozzle position for cross-duct versions
Calculating probe offset a with the geometry calculator
The probe offset can be determined with the geometry calculator delivered on the product
CD,
p. 48, §5.6.5.
1 Open the geometry calculator.
2 First select in the “Meter type” field of the “Calc transducer distance” tab whether it is a
1-path or 2-path installation.
3 Enter circumference U and wall thickness w.
4 Enter the “nominal nozzle angle” (e.g. 75, 60°, 45°).
5 Probe offset “Transducer Distance a” is calculated.
Marking the nozzle positions on the pipeline

NOTICE:
Note probe offset a and circumference U; these values are required to
calculate path angle and path length during commissioning with FLOWgate

5) Draw guide lines (1) for the nozzle positions with the previously calculated nozzle offset a, mark crossing points (2) and draw marking
points (3) in distance 60 mm (x) from the crossing points.
