Franklin Fueling Systems
(originally listed as EBW, Inc.)

AutoStik II, AutoStik Jr.
(Magnetostrictive Probe)


As of April 1, 2009, Franklin Fueling systems no longer manufactures this method.

Certification 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 = 99.9% and PFA = 0.1%. 
Leak rate of 0.1 gph with PD = 99.9% and PFA = 0.1%.
Leak Threshold 0.1 gph for leak rate of 0.2 gph. 
0.05 gph for leak rate of 0.1 gph. 
A tank system should not be declared tight if the test result indicates a loss or gain that equals or exceeds this threshold.
Applicability Gasoline, diesel, aviation fuel, fuel oil #4. 
Tank Capacity Maximum of 15,000 gallons. 
Tanks less than 95% full may be tested. 
Minimum product level required based on tank diameter is as follows:
48" dia/min 12"; 
64" dia/min 14"; 
72"dia/min 15"; 
96" dia/min 17.5"; 
126"dia/min 21.5". 
For other tank diameters, see evaluation report.
Waiting Time Minimum of 6 hours 1 minute between delivery and testing for leak rate of 0.2 gph. 
Minimum of 5 hours 18 minutes between delivery and testing for leak rate of 0.1 gph. 
None between dispensing and testing. 
There must be no delivery during waiting time
Test Period Length of the test is determined automatically based on quality of test data. 
Average data collection time during evaluation was 5 hours 10 minutes for leak rate of 0.2 gph. 
Average data collection time during evaluation was 5 hours 44 minutes for leak rate of 0.1 gph. 
Test data are acquired and recorded by a microprocessor. 
Leak rate is calculated from data determined to be valid by statistical analysis. 
There must be no dispensing or delivery during the test.
Temperature Probe contains 5 thermistors to monitor product temperature. 
At least one thermistor must be submerged in product during testing.
Water Sensor Must be used to detect water ingress. 
Minimum detectable water level in the tank is 0.208 inch. 
Minimum detectable water level change is 0.011 inch.
Calibration Thermistors and probe must be checked and, if necessary, calibrated in accordance with manufacturer's instructions.
Comments Not evaluated using manifolded tank systems. Therefore, this certification is only applicable when there is a probe used in each tank and the siphon is broken during testing. 
Tests only portion of tank containing product. 
As product level is lowered, leak rate in a leaking tank decreases (due to lower head pressure). 
Consistent testing at low levels could allow a leak to remain undetected. 
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.
