Automatic Tank Gauging (ATG)
An automatic tank gauge (ATG) is
an electronic device, whose basic function is to monitor the fuel level in the
tank over a period of time to see if the tank is leaking. It can also tell the
facility operator what is going on inside the tank (example: fuel level, volume
and temperature, water level and volume, high and low fuel level warnings).
Other features can be added to the ATG so that it can perform useful functions
such as monitoring the interstitial spaces in tanks and piping, monitoring
pressurized piping, or communicating remotely.
Components of an
Automatic Tank Gauging System:
An ATG uses probes located in each tank or compartment to
measure fuel and water levels. Each probe consists of a long rod with floats or
sensors. The position of the floats tells the ATG console how much fuel and
water are present in the tank. The probe rod also has thermistors to measure
the fuel temperature. A console is typically located inside the facility
building, and can include a display, a keypad, a printer, status lights, and a
beeper that signals alarm conditions. An ATG system may also be connected
directly to a computer.
Other Useful
Automatic Tank Gauging Functions
Besides leak detection, other key information that an ATG
can provide includes:
• Ullage Volume versus 90% Ullage. Ullage is the amount of
empty space left in the tank.
For example, an 8,000-gallon tank with 5,000 gallons of fuel
has an ullage volume of 3,000
gallons. Ninety percent ullage is the ullage minus 10% of
the tank capacity. The 90%
ullage volume is the amount of fuel that should fit in the
tank without triggering the
overfill prevention device. The 90% ullage number can be
used to determine the amount
of fuel to order.
• Gross versus Net Volume. Gasoline changes volume quite
dramatically with temperature.
For example, 10,000 gallons of gasoline will change in
volume by 7 gallons with a
temperature change of 1°F. The gross volume is the actual
volume of fuel at whatever
temperature it happens to be. The net volume is the amount
of fuel that WOULD be in
the tank IF the temperature of the fuel were 60° F. The
gross volume is the number to use
for inventory control purposes.
