AutoStik
II, AutoStik Jr., with SCALD 2.0
(INCON TSP-LL2 Magnetostrictive Probe)
CONTINUOUS
IN-TANK LEAK DETECTION METHOD (CONTINUOUS AUTOMATIC TANK GAUGING)
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 > 99% and PFA < 1%.
|
Leak
Threshold
|
0.10
gph for single and manifolded tank systems.
A tank system should not be declared tight and a message
printed for the operator, if the test results indicate
a loss or gain that 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 49,336 gallons for single tanks and for all tanks
manifolded together.
Tank must be between 14 and 93.5% full.
Contact manufacturer for tank system applications if
total tank capacity exceeds 30,000 gallons.
|
Throughput |
Monthly
maximum of 257,818 gallons. |
Waiting
Time
|
None
between delivery and data collection when difference between
product in tank and product delivered is 6.0 degrees F
or less.
|
Test
Period
|
Data
collection time ranges from 5 to 28 days. Data sampling
frequency is > 1 per second.
System collects data at naturally occurring product levels
without interfering with normal tank operation, and discards
data from unstable periods when system performs test.
|
Temperature
|
Average
for product is determined by a minimum of 5 thermistors.
|
Water
Sensor
|
Must
be used to detect water ingress.
Minimum detectable water level in the tank is 0.208 inch.
Minimum detectable change in water level is 0.011 inch.
|
Calibration
|
Thermistors
and probe must be checked and, if necessary, calibrated
in accordance with manufacturer's instructions.
|
Comments
|
System
reports a result of “pass” or “fail”.Evaluated using
both single and manifolded tank systems with probes
in each tank.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.The database for evaluation of the system
includes sites with vapor recovery and blending dispensers.
