EVO600 AND EVO6000
(FMP-LL2 & FMP-LL3 Magnetostrictive Probe)


AUTOMATIC TANK GAUGING METHOD

 

Certification

Leak rate of 0.2 gph with PD = 96.6% and PFA = 3.35%. (FMP-LL2 Probe)
Leak rate of 0.2 gph with PD = 97.64% and PFA = 2.36%. (FMP-LL3 Probe)
Leak rate of 0.1 gph with PD = 96.4% and PFA = 3.64%. (FMP-LL2 Probe)
Leak rate of 0.1 gph with PD = 95.6% and PFA = 4.36%. (FMP-LL3 Probe)

Leak Threshold

0.1 gph for leak rate of 0.2 gph.
0.05 gph for leak rate of 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, solvents, waste oil, bio-diesel and ethanol blends compatible with probe floats.

Tank Capacity

Maximum of 30,000 gallons for leak rate of 0.2 gph.
Maximum of 20,000 gallons for leak rate of 0.1 gph.
Minimum product level is 14% tank capacity.

Waiting Time

Average of 6 hours between delivery and testing for leak rate of 0.2 gph.
Average of 6 hours 4 minutes between delivery and testing for leak rate of 0.1 gph.
None between dispensing and testing.

Test Period

Length of the test is determined automatically based on quality of test data.
Average data collection time during evaluation was 7 hours 25 minutes for leak rate of 0.2 gph.
Average data collection time during evaluation was 5 hours 19 minutes for leak rate of 0.1 gph. (FMP-LL2 Probe)
Average data collection time during evaluation was 4 hours 17 minutes for leak rate of 0.1 gph. (FMP-LL3 Probe)
There must be no dispensing or delivery during the test.

Temperature

Probe contains a minimum of 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 0.201 inch (FMP-LL2 Probe).
Minimum detectable water level in the tank is 0.208 inch (FMP-LL3 Probe).
Minimum detectable water level change is 0.011 inch (Both FMP-LL2 and FMP-LL3 Probes).

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.
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.
