Facility I.D. #:Phone #:
Testing Company:Phone #: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

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
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 agrees with the value pro-
grammed into the console? Yes No Yes No Yes No Yes No
6. Water float level agrees with the value pro-
grammed into the console? Yes No Yes No Yes No Yes No
7. Inch level from bottom of stem when 90%
alarm is triggered.
8. Inch level at which the overfill alarm activates
corresponds with 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.
10. Inch level at which the water float alarm acti-
vates corresponds with 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.

induced on the line)
Metering Pressure (STP pressure when
simulated leak rate 3 gph at 10 psig)
Opening Time in Seconds (the time the
MLLD opens to allow full pressure after
simulated leak is stopped)
Does the STP pressure remain at or
below the metering pressure for at least
60 seconds when the simulated leak is
induced?
Yes No Yes No Yes No Yes No Yes No Yes No
Does the leak detector reset (trip) when
the line pressure is bled off to zero psig? Yes No Yes No Yes No Yes No Yes No Yes No
Does the STP properly cycle on/off under
normal fuel system operation conditions? Yes No Yes No Yes No Yes No Yes No Yes No
A “No” answer to either of the above questions indicates the MLLD fails the test.
