TS 750, 1000, 1001, 2000, 2001 with SCALD 2.0, TS-5, TS-608, TS-550, TS-5000
(INCON TSP-LL2 Magnetostrictive Probe)
CONTINUOUS IN-TANK LEAK DETECTION METHOD
(CONTINUOUS AUTOMATIC TANK GAUGING)
Certification Leak rate of 0.2 gph with PD > 99% and PFA < 1%.
Leak
Threshold
0.10 gph for single and manifolded tank systems.
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, fuel oil #4.
Other liquids with known coefficients of expansion and density may be tested after
consultation with the manufacturer.
Tank Capacity Maximum of 49,336 gallons for single tanks and for all tanks manifolded together.
Tank must be between 14 and 93.5% full.
Throughput Monthly maximum of 257,818 gallons.
Waiting Time None between delivery and data collection when difference between product in tank and
product delivered is 6.0 degrees F or less.
Test Period Data collection time ranges from 5 to 28 days. Data sampling frequency is > 1 per second.
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 0.208 inch.
Minimum detectable change in water level is 0.011 inch.
Calibration Thermistors and probe must be checked and, if necessary, calibrated in accordance with
manufacturer's instructions.
Comments
System reports a result of “pass” or “fail”.
Evaluated using both single and manifolded tank systems with probes in each tank.
Tests only the portion of the tank containing product.
As product level is lowered, the 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 750, 1000 and 1001 can support up to 4 tanks.
TS 2000 and 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 and 5000 can support up to 48 tanks.
TS 750 and 2000 do not provide fuel logistics, remote monitoring and other business
management options available with TS 1000, 1001, and 2001.
