TEMP VAPOR TIME - VAPOR TEMPERATURE TIME
This process variable is the last time that the tank level was updated. This variable can be viewed from the
Operate interface but cannot be modified.
LEVEL CHANGE RATE - RATE OF LEVEL CHANGE
This process variable is the rate of change of the level value due to movement of product into or out of the tank.
FuelsManager normally calculates this sampling the level at user-defined intervals and averaging the change in
level over a user-defined number of samples. However, this value can also be measured by automatic tank
gauging systems or manually entered by the operator
LEVEL RATE TIME - LEVEL RATE TIME
This process variable is the last time that the tank level change rate was updated. This variable can be viewed
from the Operate interface but cannot be modified.
GAUGE COMMAND - LEVEL GAUGE COMMAND
This process variable is used to issue commands to automatic tank gauges, the possible values depend in the
tank gauge modifier configured for the tank. This variable is normally entered by the operator, but can be linked
to automatic tank gauging systems to allow remote commands to the tank gauges
GAUGE STATUS - LEVEL GAUGE STATUS
This process variable represents the status of the automatic tank gauge. In order to use this variable the gauge
status variable must be linked to the status information data in the tank gauge. Possible statuses depend on the
tank gauge in use. This variable is normally linked to automatic tank gauging systems but can be entered by the
operator if required
GAUGE ALARMS - GAUGE ALARM FLAGS
This process variable represents the alarms present in the automatic tank gauge. In order to use this variable
the gauge alarms variable must be linked to the alarms information data in the tank gauge. This variable is
normally linked to automatic tank gauging systems but can be entered by the operator if required. Possible alarm
values depend on the tank gauge in use and can be configured by the user, the default gauge alarms are:
• 0x01-Scan Failure
• 0x02-Gauge I/O Fail
• 0x04-Device Alarm
• 0x08-Field Cfg Modified
• 0x10-Raise Failure
• 0x20-Lower Failure
• 0x40-Upload Failure
• 0x80-Download Failure
• 0x100-OverFill
