(INCON Magnetostrictive Probe)

Automatic Tank Gauging Method

Certification Leak rate of 0.2 gph with PD = 95.7% and PFA = 4.3%.
Leak rate of 0.1 gph with PD = 99.9% and PFA = 0.1%.
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, biodiesel bends B6-B20 meeting ASTM D7467, biodiesel B100 meeting ASTM D6751.
Other liquids with known coefficients of expansion and density may be tested after consultation with the manufacturer.
*NWGLDE Listings apply to leak detection functionality only and not material compatibility - see "Disclaimer".
Tank Capacity Maximum of 30,000 gallons for leak rate of 0.2 gph.
Maximum of 15,000 gallons for leak rate of 0.1 gph.
Tanks less than 95% full may be tested.
Minimum product level required based on tank diameter is as follows:
48" dia/min 12";
64" dia/min 14";
72"dia/min 15";
96" dia/min 17.5";
126"dia/min 21.5".
For other tank diameters, see evaluation report.
Waiting Time Minimum of 4 hours 9 minutes between delivery and testing for leak rate of 0.2 gph.
Minimum of 5 hours 18 minutes between delivery and testing for leak rate of 0.1 gph.
None between dispensing and testing.
There must be no delivery during waiting time
Test Period Length of the test is determined automatically based on quality of test data.
Average data collection time during evaluation was 6 hours, 51 minutes for leak rate of 0.2 gph.
Average data collection time during evaluation was 5 hours 44 minutes for leak rate of 0.1 gph.
Test data is 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 the test.
Temperature Probe contains 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 0.208 inch (0.44 inch using model TSP-IGF4P).
Minimum detectable water level change is 0.011 inch (0.013 inch using model TSP-IGF4P).
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.
TS-1000 and TS-1001 can support up to 4 tanks.
TS-2001 can support up to 8 tanks.
TS-5 can support up to 12 tanks.
TS-608 can support up to 8 tanks.
TS-550, TS-550 evo, and TS-5000 can support up to 72 tanks.
Colibri CL6 and TS-CL6 can support up to 6 tanks.
TS-750 can support up to 4 tanks, but does not provide fuel logistics, remote monitoring and other business management options available with TS-1000, TS-1001 and TS-2001.

California regulations require at least one test per month after routine product delivery or when the tank is filled to within 10% of the highest operating level of previous month. If the 0.1 gph test is used as a tank tightness test there must be no water present in the backfill (groundwater must be below the bottom of the tank), the tank must be equipped with an overfill protection device, and the product level in the tank must be at the overfill protection device set point. Local agency pre-approval is required. To use the 0.1 gph test as a monthly option see title 23 CCR Section 2643 (b)(2).
