TS 2000 
(Magnetostrictive Probe)

AUTOMATIC TANK GAUGING METHOD

Certification Leak rate of 0.2 gph with PD = 99.9% and PFA = 0.5%.
Leak Threshold 0.058 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.
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. Minimum of 2 hours between dispensing and testing. 
There must be no 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 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 minimum of 5 resistance temperature detectors (RTDs).
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 RTDs 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. TS 2000 can support up to 4 tanks.
