Facility I.D . #: Phone#:
Testing Company: Phone#: I Date:
This procedure is to determine whether the automatic tank guage (ATG) is operating properly. See PEI/RP1200 Section 8 .2 for the
inspection procedure. This procedure is applicable to tank level monitor stems that touch the bottom of the tank when in place.
Tank Number
Product Stored
ATG Brand and Model
1. Tank Volume, gallons
2. Tank Diameter, inches
3. After removing the ATG from the tank, it has
been inspected and any damaged or missing DYes DNo DYes DNo DYes DNo DYes DNo
parts replaced?
4. Float moves freely on the stem without DYes DNo DYes DNo DYes DNo DYes DNo binding?
5. Fuel float level agrees with the value pro-DYes DNo DYes DNo DYes DNa DYes DNa grammed into the console?
6. Water float level agrees with the value pro-DYes DNo DYes DNo DYes DNa DYes DNo grammed into the console?
7. Inch level from bottom of stem when 90%
alarm is triggered.
8.1nch level at which the overfill alarm activates
corresponds with value programmed in the DYes DNo DYes DNo DYes DNo DYes DNo
gauge?
9 . Inch level from the bottom when the water
float first triggers an alarm.
10. Inch level at which the water float alarm acti-
vates corresponds with value programmed in DYes DNo DYes DNo DYes DNo DYes DNo
the gauge?
If any answers in Lines 3 , 4, 5, or 6 are "No," the system has failed the test.

Testing Company: Phone#: I Date :
This procedure is to determine whether the high level alarm is operational and will trigger when the tank is no more than 90% full.
See PEijRP1200 Section 7.3 for the inspection procedure . This procedure is applicable to tank level monitor stems that touch the
bottom of the tank when in place .
Tank Number
Product Stored
Tank Level Monitor Brand and Model
1 . Tank Volume, gallons
2 . Tank Diameter, inches
3. Overfill alarm activates in the test mode at the DYes DNo DYes DNo DYes DNo DYes DNo console?
4. When activated , overfill a larm can be heard or DYes DNo DYes DNo DYes DNo DYes DNo seen while delivering to the tank?
5. After removing the probe from the tank , it has
been inspected and any damaged or missing DYes DNo DYes DNo DYes DNo DYes DNo
parts replaced?
6 . Float moves freely on the stem without binding? DYes DNo DYes DNo DYes DNo DYes DNo
7. Moving product level float up the stem trigger DYes DNo DYes DNo DYes DNo DYes DNo alarm?
8. Inch level from bottom of stem when 90% alarm
is triggered.
9. Tank volume at inch level in Line 8 .
10. Calculate (Line 9 1 Line 1 ) x 100
11. Is Line 10 less than 90%? DYes DNo DYes DNo DYes DNo DYes DNo
12. Fuel float level on the console agrees with the DYes DNo DYes DNo DYes DNo DYes No gauge stick reading?
13. Overfill alarm activates at any product level DYes DNo DYes DNo DYes DNo DYes DNo above 90% tank capacity?
If any answers in Lines 3 , 4, 5, 6 , 7 or 11 are "No ," or Line 13 is "Yes ," the system has fa iled the test.
