The relevant temperature correction is deactivated.
linear
The correction factors GA03 T-crr fact orifice and GA04 T-crr fact pipe are calculated using the linear heat
expansion coefficients GA05 Lin.expanse orifice and GA06 Lin.expanse pipe.
T Ber . fakt  1  A.lin  (Temp  20)
Material selection
The correction factors GA03 T-crr fact orifice and GA04 T-crr fact pipe are calculated using an approximation
equation
and the coefficients A and B.
T Ber. fakt  1  ( A  (Temp  20)  B  (Temp  20) 2 )  106
Coefficients are assigned automatically when a material is selected.
The permitted temperature range for the materials listed extends from -200°C to 600°C, with the exception
of copper, nickel and brass, which have an upper limit of 500°C.
