EBW, Inc.

Auto-Stik II, Auto-Stik Jr.
(INCON, EBW LL2 Magnetostrictive Probe)

Automatic Tank Gauging Method

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

Certification Applies only to EBW, Inc. AutoStik II and AutoStik Jr., with SCALD 2.0 models sold on or after March 1, 2004.
Leak rate of 0.2 gph with PD = 95.7% and PFA = 4.3%.
Leak Threshold 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.
Other liquids with known coefficients of expansion and density may be tested after consultation with the manufacturer.
Tank Capacity Maximum of 30,000 gallons.
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";
72"dia/min 15";
96" dia/min 17.5";
126"dia/min 21.5".
For other diameters, see evaluation report.
Waiting Time 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.
Test Period 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 minutes.
Test data is acquired and recorded by system's computer.
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 inches.
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.
This equipment 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 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.

California regulations require at least one test per month after routine product delivery or when the tank is filled to within 10% of the highest operating level of previous month.
