Purging Air in DEF Systems
Because of the meter’s sensitivity to aeration of the fluid, it is suggested when first purging the
unit of air to temporarily install a standard Atlas pulser to the 9800 CPU Board for the first
purged (farthest from tank) Coriolis Meter. The standard Atlas pulser is shown in
on
To install a standard Atlas pulser, proceed as follows:
1
Remove power to the unit.
2
Disconnect the pulser data connection at the Pulser Adapter Cable and connect a standard
Atlas pulser.
3
Restore power and activate the dispensing position.
4
Slowly hand spin the pulser to allow air to be purged through the system with the nozzle
activated.
5
Purge the air, following the normal procedures, until DEF with minimal air is being dispensed.
6
Remove power to the unit.
7
Remove the temporary pulser and replace with the data connector from the Coriolis Meter.
