 OEL 8000 II, K-OEL 8000 II, OEL8000 III (Proteus Series-B, K and X) Monitoring System with CITLDS
(MTG-XX Magnetostrictive Probe)

(Continuous Automatic Tank Gauging)

Certification Leak rate of 0.2 gph with PD = 99% and PFA = 1%.
Leak Threshold 0.1 gph.
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.
The system is designed primarily for use with petroleum fuels.
Tank Capacity Maximum of 18,000 gallons.
Throughput Monthly maximum of 154,195 gallons.
Waiting Time The automatic data collection program allows for 20 minutes for waiting time after the product delivery and stabilization. Once product has settled after a delivery, waiting time is a minimum of 20 minutes.
Test Period Data collection time ranges from 3 hours to 14 days.
Data sampling frequency is every 17 seconds.
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 0.055 inch.
Minimum detectable change in water level is 0.011 inch.
Calibration Probe must be checked annually and, if necessary, calibrated in accordance with manufacturer's instructions.

System reports a result of "pass" or "fail."
Not evaluated using manifolded tank systems. Therefore, this certification is only appplicable when there is a probe used in each tank and the siphon is broken during testing.
System distinguishes large leak rates (> 1gph) from dispensing activities and reports those as "fail".
For valid monthly testing, a conclusive test report must be produced for each tank every month.
System warns operator if there are no "passing" tests completed during the month.
For very active tanks, a tank shut down may become necessary in order for the system to collect enough quiet-time data for a test.
Constant and variable leaks were mathematically induced into tight tank test records which were collected by systems installed at various active tank sites.
During the evaluation, data was collected when the product level was between 12.7% and 97.9% of tank volume.
The database for evaluation of the system included sites with vapor recovery.
Tanks used in this evaluation contained gasoline and diesel.
Omntec has stated that the software and algorithm from the original system and is also being used on the new Proteus console and the third-party evaluator has confirmed that the new software and algorithm produce results identical results to the original evaluation when processed through the Proteus console software.
