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
FittingAdjust [mm] = 1 mm Compensation when tightening the self-cutting ring fitting (self-cutting ring fitting
displaces the duct probe by 1 mm when tightened)
