6.3.2.2
Total volume measurement
“A” + “B” is calculated as the total volume measurement for the volume / mass measure-
ment. There is no return identification. Separate K factors are applied.
The total of “A+B” is displayed at all meters. K factor A and B can be set separately.
Select operating mode “2”.
6.3.2.3
Difference measurement
“A-B” is calculated as the difference measurement for the volume / mass measurement.
There is no return identification. Separate K factors are applied.
The electronics can record pulses from two different measuring chambers. The forward
quantity is, e.g., measured by the internal reed sensor “A”. The external reed sensor then
measures the pulses of the separately mounted return quantity meter via the external reed
sensor “B” (terminal positions 1+2). A K factor must be programmed for each sensor. The
difference “A-B” is displayed at all the meters. A number below zero is impossible; the
smallest value that can be displayed at the volume meter is “0”. Select operating mode “3”.
6.3.3
Volume units (level 2)
The displayed volume unit can be freely selected (litters, cubic meters, gallons, grams, kilo-
grams, tonnes).
There is no automatic conversion of the previously accumulated volume in the new unit when
changing the selected volume unit in level 2 or when changing the number of digits after the
decimal point for V in level 5. All the current meter readings are deleted (reset) when chang-
ing the volume unit. It is recommended to activate password protection to prevent accidental
deletion. Always observe possible effects on the current output.
Mass display
To display the mass, a fixed density in kg/m³ and an alpha value in kg/m³/°C must be entered
in the programming menu. The density and the alpha value are used to convert volumes to
mass. When selecting a mass volume unit (g, kg or t), the calculated or fixed density is ac-
cessed automatically depending on whether a temperature sensor is connected or not.
6.3.4
Time units (level 3)
The time unit for the flow display (h/ min/ s) can be freely selected.
