OPERATING MANUAL HPC & UMC4
14.6.1 Density measurement on/off
This function allows the operator to activate density measurement. After selecting the
Density measure-
ment on/off
function, press
„Enter“ to display the following selection field:
Measurement
[on]
As mentioned in Section 13.4.3.1 Selection window/make a selection, the operator can choose between
the following settings:
on
density measurement is switched on
off
density measurement is switched off
fixed
density measurement is switched off; a fixed replacement value will be displayed
and used for volume flow measurement
To confirm and apply the selection, press
„Enter“. If density measurement was switched on and the mes-
sage “Density not calibrated” is displayed, no density calibration was carried out by the vendor.
Density measurement can only be activated if density calibration has been carried out properly.
Density calibration is realized at the factory using the service password.
If no density calibration has been carried out, the density and volume flow values will be set to
“0.0” in the MEASURED VALUES functional class and the message “Density unknown” will be displayed.
14.6.2 Density unit
This function allows the operator to define the physical unit for all display functions and the density lower-
and upper-range value. After selecting the
Density unit
function, press
„Enter“ to display the following
selection field:
Density unit
[g/l]
As mentioned in Section 13.4.3.1 Selection window/make a selection, the operator can choose between
the following units:
g/l, kg/m³
kg/l
g/cm³
lbs/ft³
lbs/USG, lbs/USB
xxx
Press
„Enter“ to confirm and apply the selection.
A conversion factor can be entered as a substitute for a not available density as described in the after-
following section 14.6.3
“Factor programmable density unit” on page 65.
