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.


Gasoline, diesel, aviation fuel, fuel oil #4, biodiesel blends B6-B20 meeting ASTM D7467, biodiesel B100 meeting ASTM D6751.

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.


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.


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 (0.44 inch using model TSP-IGF4P).
Minimum detectable change in water level is 0.011 inch (0.013 inch using model TSP-IGF4P).


Thermistors and probe must be checked and, if necessary, calibrated in accordance with manufacturer's instructions.


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, TS-1000 and TS-1001 can support up to 4 tanks.
TS-2000 and 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 evo and TS-5000 can support up to 48 tanks.

Colibri CL6 and TS-CL6 can support up to 6 tanks
TS-750 and TS-2000 do not provide fuel logistics, remote monitoring and other business management options available with TS-1000, TS-1001, and TS-2001.
The database for evaluation of the system includes sites with vapor recovery and blending dispensers.

The FMP-LL3 probe may be configured to operate as an LL2 model.
