AUTOMATIC TANK GAUGING METHOD
As of April 1, 2009, Franklin Fueling systems no longer
manufactures this method.
Applies only to AutoStik II and AutoStik Jr. models
sold March 1, 2004 to April 1, 2009.
Leak rate of 0.2
gph with PD = 95.7% and PFA = 4.3%.
A tank system should not be declared tight if the test result indicates a
loss or gain that equals or exceeds this threshold.
aviation fuel, fuel oil #4.
||Maximum of 30,000
Tanks less than 95% full may be tested.
Minimum product level required based on tank diameter as follows:
48" dia/min 12";
64" dia/min 14";
96" dia/min 17.5";
For other diameters, see evaluation report.
||Minimum of 4
hours 9 minute between delivery and testing.
Minimum of 2 hours between dispensing and testing.
There must be no delivery during waiting time.
||The length of the
test is determined automatically based on quality of test data.
Average data collection time during the evaluation was 6 hours, 51
Test data is acquired and recorded by system's computer.
Leak rate is calculated from data determined to be valid by statistical
There must be no dispensing or delivery during the test.
||Probe contains 5
thermistors to monitor product temperature.
At least one thermistor must be submerged in product during testing.
||Must be used to
detect water ingress.
Minimum detectable water level in the tank is 0.208 inches.
Minimum detectable water level change is 0.011 inch.
probe must be checked and, if necessary, calibrated in accordance with
using manifolded tank systems. Therefore, this certification is only
applicable when there is a probe used in each tank and the siphon is broken
was not evaluated using manifolded tanks.
Tests only the portion of the tank containing product.
As product level is lowered, the leak rate in a leaking tank decreases
(due to lower head pressure).
Consistent testing at low levels could allow a leak to remain
EPA leak detection regulations require testing of the portion of the tank
system which routinely contains product.
AutoStik Jr. can
support up to 4 tanks.
AutoStik II can support up to 8 tanks.
