CONTINUOUS IN-TANK LEAK DETECTION METHOD (CONTINUOUS AUTOMATIC TANK GAUGING)
|
Certification
|
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.
TS 750, 1000 and 1001 can support up to 4 tanks.
TS 2000 and 2001 can support up to 8 tanks.
TS 5 can support up to 12 tanks.TS 608 can support up
to 8 tanks.
TS 550 and 5000 can support up to 48 tanks.
TS 750 and 2000 do not provide fuel logistics, remote
monitoring and other business management options available
with TS 1000, 1001, and 2001.
The database for evaluation of the system includes sites
with vapor recovery and blending dispensers. |
