Automatic Tank Gauge Functionality Testing
Functionality verification on most ATG types. PTTI is certified to test Veeder-Root and Franklin INCON systems.
Manufacturer-certified · Testing UST & AST systems since 1997 · Serving 13 states and expanding
PTTI tests the functionality of Veeder-Root, Franklin INCON, and other ATG systems.
Testing Method
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 test Veeder-Root and Franklin INCON systems.
- Frequency
- Annual functionality testing for applicable release-detection components, or more often where required.
- Deliverable
- A record of the ATG functionality checks and observed results, with relevant console records where applicable.
Common Automatic Tank Gauge Failure Modes
-
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.
ATG Functionality Testing, frequently asked.
Which ATG systems does PTTI test?
PTTI tests the functionality of Veeder-Root, Franklin INCON, and other ATG systems. PTTI is certified to test Veeder-Root and Franklin INCON systems.
How often is ATG functionality testing required?
Applicable release-detection components require annual functionality testing. This is separate from the system’s ongoing release-detection monitoring.
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.
