Table 7: Temperature correction for orifice plate and pipe
Off
The corresponding temperature correction is switched off.
Linear
The correction factor GA03 T-crr.fact. orifice or GA04 T-crr.fact. p ipe is calculated
with the linear heat expansion coefficient GA05 lin.expans. orifice or GA06
lin.expans. pipe .
ܩܣͲ͵ ൌ ͳ ൅ Ͳͷ ڄ ሺܶ െ ʹͲሻ
The temperature
T
is relative to °C; the Pipe T-calc.fact takes place analogously.
Material selection
The correction factor GA03 T-crr.fact. orifice or GA04 T-calc.fact p ipe is calculated
with a proximity equation and coefficients A and B.
