Certification

Leak rate of 3.0 gph at 10 psi* with PD = 100% and PFA = 0%. 
Leak rate of 0.2 gph at operating pressure with PD = 100% and PFA = 0%. 
Leak rate of 0.1 gph at 1.5 times operating pressure* with PD = 100% and PFA = 0%.
*Since leak rate varies as a function of pressure, this leak rate and pressure were certified using an equivalent leak rate and pressure, in accordance with an acceptable protocol.

Leak Threshold

1.5 gph for leak rate of 3.0 gph.
0.1 gph for leak rate of 0.2 gph.
0.05 gph for leak rate of 0.1 gph. 
A pipeline system should not be declared tight if the test result indicates a loss that equals or exceeds this threshold.

Applicability

Gasoline, diesel, aviation fuels, fuel oil #4, waste oil, kerosene. 
Other liquids may be tested after consultation with the manufacturer.

Specification

Pipeline Capacity

Maximum of 312.2 gallons for steel and fiberglass pipelines (examples: 480 feet of 4 inch line; 671 feet of 3 3/8 inch line ).
Maximum of 95.4 gallons for flexible pipelines (examples: 260 feet of 3 inch line; 1040 feet of 1 ½ inch line).
Maximum of 415.8 gallons for combination rigid and flexible pipelines (the capacity of the flexible component cannot exceed 95.4 gallons).

Waiting Time

None between delivery and testing. 
None between dispensing and testing for leak rate of 3.0 gph. 
Depending on temperature stability, 1½ to 10 hours between dispensing and testing for leak rates of 0.2 gph and 0.1 gph. 

Test Period

Response time is 1 to 2 minutes for leak rate of 3.0 gph. 
Minimum of 25 minutes for leak rate of 0.2 gph. 
Minimum of 34 minutes for leak rate of 0.1 gph. 
Test data are acquired and recorded by a microprocessor.

System Features

Permanent installation on pipeline. 
Automatic testing of pipeline every 45 minutes for leak rate of 3.0 gph. 
Automatic testing of pipeline when pump has been idle for 2 hours for leak rate of 0.2 gph. 
Automatic testing of pipeline when pump has been idle for 3½ hours for leak rate of 0.1 gph.  
Pump shutdown, indicator light and alarm activation if leak is declared for 3.0 gph and 0.2 gph tests.
The TS-LS500E series is an explosion proof version of the original TS-LS500 series.

Calibration

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