6.4.14 Superheated Steam Density Setup (SPEC. WEIGHT (SUP))
As the parameters associated with the density of superheated steam, their measurement units are set up here.
※ The units to be set here are on-screen units in the RUN mode, and they by no means affect
calculation and other settngs.
＜Calculation Formula＞
where Ｔ：Temperature（℃）
Ｐ：Abs. pressure（Ｐ＝Ｐ’+ 0.101325）
Ｐ’：Line pressure（MPa）
α, β, γ：Coefficients for pressure

① Superheated steam density unit setup (UNIT)
The unit for superheated steam density calculation is set up here.
Superheated steam density submenu screen p. 92
←Unit option select setup
For details of selecting options setup, see “(2) Option select setup screen
(SELECT)” on page 46.
The unit you can choose from are “kg/m
3
”, “g/l”, “g/cm
3
”, “kg/l”, and or “g/ml”.
※ The unit to be set is that of the density displayed in the RUN mode.
※ Depending on the unit chosen here, the numerical format (number of
decimal places) of relative density (specific weight) shown in the RUN
mode varies. When you modify it, carefully take into account the count
capacity and the number of decimal places to be shown.
