GAUGE ALARMS BIT XX - GAUGE ALARMS
This process variable represents the individual elements of the Gauge Alarm Flags. Where gauge alarms bit 00
represents the state of the lowest bit of the gauge alarm flags and gauge alarms bit 15 represents the highest bit
of the gauge alarm flags. Possible values for each gauge alarms bit are Normal or the coded variable associated
with the particular bit. In the example above gauge alarms bit 00 - Normal or Scan Failure
TEMP TANK AMBIENT - AMBIENT TANK TEMPERATURE
This process variable is the ambient temperature of the air surrounding the tank. This variable is normally
entered by the operator, but can be linked to automatic tank gauging systems. In addition, this variable supports
linking to a 'local' FuelsManager database point, this allows multiple tanks to read one common ambient
temperature
VOLUME CORRECTION - TANK VOLUME CORRECTION
This process variable is the unmeasurable volume associated with line segments and manifolds connected to
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
VOL. CORRECTION TIME - VOLUME CORRECTION TIME
This process variable is the last time that the tank volume correction was updated. This variable can be viewed
from the Operate interface but cannot be modified
VAPOR DENSITY - VAPOR DENSITY
This process variable is the density of the gas in the vapor space above the product in 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. This data is normally only applicable to tanks containing liquified hydrocarbons or
tanks using hydrostatic or hybrid tank calculations
VAPOR DENSITY TIME - VAPOR DENSITY TIME
This process variable is the last time that the tank gas density was updated. This variable can be viewed from
the Operate interface but cannot be modified
VAPOR PRESS P3 - VAPOR PRESSURE P3
This process variable is the pressure of the vapor space above the product in the tank. This variable is usually
measured by automatic tank gauging but can be manually entered by the operator. This data is normally only
applicable to tanks containing liquified hydrocarbon or those using hydrostatic or hybrid tank calculations
VAPOR PRESSURE TIME - VAPOR PRESSURE TIME
This process variable is the last time the Vapor Pressure P3 was updated. This variable can be viewed from the
Operate interface but cannot be modified. This variable is usually measured by automatic tank gauging but can
be manually entered by the operator. This data is normally only applicable to tanks containing liquified
hydrocarbon or those using hydrostatic or hybrid tank calculations
MIDDLE PRESSURE P2 - HYDROSTATIC PRESSURE P2
