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
4.
The units for this group are dependent on the value of the heating select bit accessed via
register app.6.5. For a “0” the group is HV Volume, for “1” the group is HV Mass.
5.
If the transducer is a gage transducer and gage logging is selected then the value logged here
will be the log period average pressure – log period average barometric pressure. The units will
be those defined in the absolute pressure group.
