11.9 Menu7: Density table2
o Entry of two density tables when using different liquids
o Enables temperature compensation and mass calculation of the flow values
o The density table can be requested from the supplier of the liquid.
o Selection of the density table used, see 2.09Select setting density determination
o Changes only possible with password

...
7.10Density table2
Point10
Example with a density value:
o Point1: Temperature value and associated density value
o Point2: Density value0
Example with three density values:
o Point1: Temperature value and associated density value
o Point2: Further temperature value in ascending order and associated density value
o Point3: Further temperature value in ascending order and associated density value
o Point4: Density value0
Note:
The number of density table values is limited by the input of the density value0 . A density value for
the minimum and maximum temperature respectively is added automatically to the density table. The
value for the minimum temperature (-40°C) is determined internally by extending the linearizations
between the first two points. The value for the maximum temperature (200°C) is determined internally
by extending the linearizations between the last two points.
If only one density value is entered, display with a mass unit without connection of a temperature
sensor is also possible. Prerequisite is that the process temperature is constant and is known and that
the density at this temperature has been entered.
11.10 Menu 8: Alarms
The electronic unit evaluates different measured values during operation and analyzes the operating
state. If an error occurs, an alarm message is displayed. This provides information used to eliminate
the error.
Confirming the alarm. The alarm message disappears from the dis-
play. Suitable measures for eliminating the error can be taken sub-
sequently.

Activated alarm displayed again
If an alarm occurs, Relay output2 Group error message is also activated.
