Automatic tank gauge functional testing.
Functional verification on every ATG type. PTTI is certified to work on Veeder-Root and Franklin INCON systems in every state we service.
Manufacturer-certified · EPA 40 CFR Part 280 · Testing tanks since 1997
Automatic tank gauge functional verification on Veeder-Root (TLS-300, TLS-350, TLS-450, and others), Franklin INCON, and other ATG systems.
How we run it.
PTTI follows the PEI RP1200 Appendix C-7 procedure. The technician removes the ATG probe, inspects the floats for free movement and damage, and reconnects.
The fuel float is set at the probe midpoint and the console reading is verified. The float is then moved upward until the high-product alarm triggers. The distance from the probe bottom is measured and compared to the programmed alarm value.
The procedure repeats with the water float and water alarm. System configuration and alarm histories are printed from the console for the inspection record. PTTI is certified to work on Veeder-Root and Franklin INCON systems in every state we service.
- Equipment
- Tools for ATG probe removal. Tape measure or gauge stick. Console-printed test record.
- Frequency
- Functional verification on the schedule your state's UST program requires. The system performs a passing leak test every 30 days under EPA 40 CFR Part 280.
- Deliverable
- An audit-ready ATG functional test record, with the console configuration and alarm history captured on site and sent after the visit. It gives your file the proof the monthly monitoring requirement is met. PTTI prepares the record; your operator files it with the state.
What we look for.
-
1
Sensor floats stuck or inaccurate
Float movement restricted, readings drift, or alarms fail to trigger at programmed thresholds.
-
2
Probe length or depth issues
Probes not reading at the proper length, requiring recalibration or replacement.
-
3
Wiring or connector degradation
Top-connector failure, wiring needing replacement, or floats falling off the probe entirely.
Frequently asked.
Which ATG systems does PTTI test?
All Veeder-Root systems (TLS-300, TLS-350, TLS-450, and others) and all Franklin INCON systems, plus others. PTTI is certified to work on Veeder-Root and Franklin INCON systems in every state we service.
How often does an ATG need functional verification?
Functional verification is performed on the schedule your state's UST program requires. Separately, the system performs a passing leak test every 30 days to satisfy the federal monthly-monitoring requirement under EPA 40 CFR Part 280.
What happens if a sensor fails?
PTTI documents the specific failure, whether a stuck float, a probe-length issue, or wiring degradation, and prints the console configuration and alarm history for the record. PTTI prepares the documentation; the operator files it with the state.
