Example for 75°
Simplified:
β [°] = Nominal nozzle installation angle
NozzleLength [mm] = Nozzle length D1 or D2; dimension on nozzle installation tool
GasketThickness [mm] = Dimension of gasket thickness
LengthBallValve [mm] = Length of ball valve, measure from gasket surface to gasket surface
WallThickness [mm] = Wall thickness of pipe
120,79 mm = Probe 1-path distance inner pipe wall to first probe A
82,189 mm = Probe 2-path distance inner pipe wall to first probe A
206,4 mm = Distance probe A to end of probe
330,45 mm = Probe 1-path wetted part length in pipe
290,48 mm = Probe 2-path wetted part length in pipe
0,966 = sin(75°) – Nominal nozzle installation angle
FittingAdjust [mm] = 1 mm Compensation when tightening the self-cutting ring screw fitting (self-cutting ring fitting displaces
the duct probe by 1 mm when tightened)
