This procedure is to determine whether the automatic tank gauge (ATG) is operating properly. See PEI/RP1200 Section 8.2 for the inspection
procedure. This procedure is applicable to tank monitor stems that touch the bottom of the tank when in place.
Tank Number 1 (NW) 2 (SW) 3 (E)
Product Stored DSL RUL DSL
ATG Brand and Model TLS 350 TLS 350 TLS 350
1. Tank Volume, gallons 11,527 11,527 11,527
2. Tank Diameter, inches 89.75 89.75 89.75
3. After removing the ATG from the tank, it has been
inspected and any damaged or missing parts replaced? ☒Yes ☐No ☒Yes ☐No ☒Yes ☐No ☐Yes ☐No
4. Float moves freely on the stem without binding? ☒Yes ☐No ☒Yes ☐No ☒Yes ☐No ☐Yes ☐No
5. Fuel float level agree with the value programmed into
the console? ☒Yes ☐No ☒Yes ☐No ☒Yes ☐No ☐Yes ☐No
6. Water float level agree with the value programmed into
the console? ☒Yes ☐No ☒Yes ☐No ☒Yes ☐No ☐Yes ☐No
7. Inch level from the bottom of the stem when 90% alarm
is triggered? 75 75 75
8. Inch level at which the overfill alarm activates
corresponds with the value programmed in the gauge? ☒Yes ☐No ☒Yes ☐No ☒Yes ☐No ☐Yes ☐No
9. Inch level from the bottom when the water float first
triggers an alarm? 2 2 2
10. Inch level at which the water float alarm activates
corresponds with the value programmed in the gauge? ☒Yes ☐No ☒Yes ☐No ☒Yes ☐No ☐Yes ☐No
If any answers in Lines 3, 4, 5, or 6 are "No" the system has failed the test.
Test Results ☒Pass ☐Fail ☒Pass ☐Fail ☒Pass ☐Fail ☐Pass ☐Fail

This procedure is to determine whether liquid sensors, located in the interstitial spaces of the UST systems, are able to detect the presence of water and fuel. See
PEI/RP1200, Section 8.3 for the test procedure.

Is the ATG Console clear of any active or
recurring warnings or alarms regarding
the leak sensor? If the sensor is in alarm
and functioning, indicate why.
☒ Yes ☐ No ☒ Yes ☐ No ☒ Yes ☐ No ☒ Yes ☐ No ☒ Yes ☐ No ☒ Yes ☐ No ☐ Yes ☐ No
Is sensor alarm circuit
operational? ☒ Yes ☐ No ☒ Yes ☐ No ☒ Yes ☐ No ☒ Yes ☐ No ☒ Yes ☐ No ☒ Yes ☐ No ☐ Yes ☐ No
Has sensor been inspected and in good
operating condition? ☒ Yes ☐ No ☒ Yes ☐ No ☒ Yes ☐ No ☒ Yes ☐ No ☒ Yes ☐ No ☒ Yes ☐ No ☐ Yes ☐ No
When placed in test liquid, does the
sensor trigger an alarm? ☒ Yes ☐ No ☒ Yes ☐ No ☒ Yes ☐ No ☒ Yes ☐ No ☒ Yes ☐ No ☒ Yes ☐ No ☐ Yes ☐ No
When alarm is trigger, is the sensor
identified on the ATG console? ☒ Yes ☐ No ☒ Yes ☐ No ☒ Yes ☐ No ☒ Yes ☐ No ☒ Yes ☐ No ☒ Yes ☐ No ☐ Yes ☐ No
Any “No” answers indicate the sensor fails the test.
