AUTOMATIC
TANK GAUGING METHOD
|
Certification
|
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.
TS1000 and 1001 can support up to 4 tanks.
TS2001can support up to 8 tanks.TS
750 can support up to 4 tanks, but does not provide fuel
logistics, remote monitoring and other business management
options available with TS 1000, 1001 and 2001.
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.
