OEL 8000, K-OEL 8000, OEL 8000 II,
K-OEL 8000 II, OEL 8000 III Series Consoles (Proteus B, K, and X Consoles), 
(MTG - XX Magnetostrictive Probe)


Certification Leak rate of 0.2 gph with PD = 97.5% and PFA = 2.5%.
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, biodiesel blends B6-B20 meeting ASTM D7467, biodiesel B100 meeting ASTM D6751 
Tank Capacity Maximum of 30,000 gallons. 
Tanks less than 95% full may be tested. Minimum product level required is based on tank diameter as follows:
48" dia/ min 12"; 
64" dia/ min 15"; 
72" dia/ min 16"; 
96" dia/ min 20"; 
126" dia/ min 25"; 
132" dia/ min 26". 
For other tank diameters, consult manufacturer.
Waiting Time Proteus Series OEL 8000III: Minimum of 4 hours between delivery and testing. OEL Series: Minimum of 4 hours between delivery and testing. 
There must be no delivery during waiting time.
Test Period Proteus Series OEL 8000III: Minimum of 4 hours. OEL Series: Minimum of 4 hours, 30 minutes.  Test data are acquired and recorded by the controller. 
Leak rate is calculated from data determined to be valid by statistical analysis. 
There must be no dispensing or delivery during test.
Temperature Average for product is determined by a probe containing a minimum of 5 thermistors. 
At least one thermistor must be submerged in product during test.
Water Sensor Must be used to detect water ingress. 
Minimum detectable water level in the tank is 0.055 inch. 
Minimum detectable change in water level is 0.011 inch.
Calibration No calibration required.
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. 
Proteus Series OEL 8000III: evaluated with both 2 and 4 inch diameter floats. OEL Series: evaluated with only 4 inch diameter floats.
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.
