(Magnetostrictive Probe)
AUTOMATIC TANK GAUGING METHOD
| Certification |
Leak rate of 0.2
gph with PD = 100% and PFA = 0%. |
| 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, biodiesel blends B6-B20 meeting ASTM D7467, biodiesel B100
meeting ASTM D6751.
|
| Tank
Capacity |
Maximum of 15,000
gallons.
Tank must be between 50 and 95% full. |
| Waiting
Time |
Minimum of 6
hours between delivery and testing.
There must be no dispensing or delivery during waiting time. |
| Test
Period |
Minimum of 3
hours.
Test data are acquired and recorded by system's computer.
Leak rate is calculated from all data collected.
There must be no dispensing or delivery during test. |
| Temperature |
Average for
product is determined by a minimum of 5 temperature sensors. |
| Water
Sensor |
Must be used to
detect water ingress.
Minimum detectable water level in the tank is 1.04 inches.
Minimum detectable water level change is 0.011 inch. |
| Calibration |
Temperature
sensors 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. |
