Use this parameter to select the unit for the mass flow (mass/time).
The unit you select here is also valid for:
• Simulation
• Low flow cut off
• Display value (local display)
Options:
Metric:
gram → g/s; g/min; g/h; g/day
kilogram → kg/s; kg/min; kg/h; kg/day
Metric ton → t/s; t/min; t/h; t/day
US:
ounce → oz/s (US); oz/min (US); oz/h (US); oz/day (US)
pound → lb/s; lb/min; lb/h; lb/day
ton → ton/s; ton/min; ton/h; ton/day
Factory setting:
Nominal diameter and country dependent → Page 123 ff.
!
Note!
The unit selected here does not have any effect on the desired mass flow
unit which should be transmitted by means of the FOUNDATION
Fieldbus interface. This setting is made separately by means of the
corresponding AI Block in the XD_SCALE parameter group.
Use this function to view the set density.
This density value can be modified by means of the "Density Param. -
Fixed Value" parameter ( → Page 87).
Factory setting:

!
Note!
The unit is displayed in the "System Unit - Fixed Density" parameter
( → Page 80).
Use this parameter to select the unit for displaying the fluid density.
The unit you select here is also valid for:
• Density entry "Density Param. - Fixed Value", → Page 87)

; lb/gal; lb/bbl (normal fluids); lb/bbl (beer); lb/bbl
(petrochemicals);
lb/bbl (filling tanks)
Imperial → lb/gal; lb/bbl (beer); lb/bbl (petrochemicals)
Factory setting:
kg/l (SI units: not for USA and Canada)
g/cc (US units: only for USA and Canada)
SD = Specific Density, SG = Specific Gravity
The specific density is the ratio of fluid density to water density
(at water temperature = 4, 15, 20 °C).
