SECTION 4
VOLUME - Contents Measurement with Volumetric Conversion Default Program
Changing the application to volume measurement loads this default program into memory.

Pr.4.0 Blanking 0.500m
Pr.3.0 Operational
Span
5.500m
Pr.8.2.1.2
R2 Set

This default program is created to do the following:-
To measure the level in a flat bottomed tank. Dimensions as shown.
Output/display in m³.
Analogue output to be 4-20mA proportional to volume in tank.
High alarm at 90% volume.
Low alarm at 10% volume.
This program can be easily modified to suit the required application. You should delete from
this program any unwanted entries (e.g. Relay 3 L.O.E.).
Parameter Default Description
number Setting
2.0 Empty Distance = 6.000 Distance from transducer to zero level.
3.0 Operational Span = 5.500 The span, based on zero level.
4.0 Blanking = 0.500 Blanking zone into which level should not rise.
5.0 RateOfChange = 1.000 The maximum rate of change of liquid level in
metres/minute.
6.1 Vessel Shape = 6.1.1 Linear Vessel Define vessel as linear vessel
6.2 Display Units = 6.2.7 Units % Display in %
8.1 Rly1 Options = 8.1.1 Relay 1 Norm-Energised Relay 1 to alarm on volume (normally
energised)
8.1.1.1 Relay 1 Set = 90 Relay 1 to de-energise at 90% to indicate high
alarm.
8.1.1.2 Relay 1 Reset = 85 Relay 1 to re-energise at 85% to clear the high
alarm.
8.2 Rly2 Options = 8.2.1 Relay 2 Norm-Energised Relay 2 to alarm on volume (normally
energised)
8.2.1.1 Relay 2 Set = 10 Relay 2 to de-energise at 10% to indicate low
alarm.
8.2.1.2 Relay 2 Reset = 15 Relay 2 to re-energise at 15% to clear the low
alarm.
8.3 Rly3 Options = 8.3.4 Relay 3 L.O.E. Alarm Relay 3 (L.O.E. Alarm)
To simulate the program go to 12.5.2 yes then press ENT again.
