Tube Floating Point Register Notes:
1.
Static pressure values are in absolute or gauge depending on gauge pressure device selection.
See Tube Byte Register 0.55.
2.
Flow Rate Limits units depend on Flow rate / volume scale flags. See Tube Byte Register 0.42.
3.
The units for this group are dependent on the value of the heating select bit accesed via register
app.6.5. For a “0” the group is HV Volume, for “1” the group is HV Mass.
4.
LCP Integral – this is the square root of the static pressure * differential pressure / flowing
temperature. For Selectable Units this field is always calculated as:
static
pressure:
bar
diff
pressure:
mbar
temperature:
deg
Kelvin
5.
LCP Fip – for the current implementation Fip is calculated as follows:
Fip = xpt * sqrt_rgrav * sqrt(( 2 * Mair / Rgc ) * (1/Zba)) * Fpv
Where: xpt =
see note 4 above
Sqrt_rgrav = square root of the real specific gravity
Mair = 28.9625
Rgc
=
0.0831451
Zba = compressibility of air as entered by the user
Fpv = calculated super compressibility
