An Automated Tank Gauge (ATG) is more than just a piece of equipment—it’s your facility’s first line of defense against costly fuel releases, inventory loss, and compliance violations. But owning an ATG isn’t enough. Managing it the right way, every day, is what protects your business.

PASS Training & Compliance has put together a field-tested best practices guide to help owners and operators take control of their ATG and avoid preventable issues.

Why ATGs Matter

Modern ATGs track:

Fuel levels
Water intrusion
Temperature
Leak test results
Sensor alerts (sumps, interstitials, etc.)

They also provide alarms and logs that can be printed, stored digitally, or shared with regulators. But too often, these alerts are misunderstood, ignored, or mismanaged—creating avoidable risk.

ATGs act as the digital record-keeper for your fuel system. Each tank test result, sensor alert, and alarm acknowledgment is stored within the system. Many models can generate a printed ticket for leak tests or inventory reports. Others allow for digital report downloads. This creates a reliable audit trail—whether you're proving compliance to inspectors or just tracking issues over time.

What to Do Daily and Weekly

Daily:

Confirm the ATG console is powered on and shows no active alarms
Review leak test results for each tank (ensure a recent "PASS" exists)
Check fuel and water levels (and act if water is detected)

Weekly:

Inspect the ATG console, printer, and sensors
Test alarm lights and sounds
Ensure sump sensors are dry and properly seated
Check for damage or loose wiring

Interpreting Alarms

High or Low Fuel Level: Plan deliveries or halt overfills
Water Detected: Remove water promptly to avoid corrosion or fuel quality issues
Leak Test Fail: Investigate immediately—this may indicate a real release
Sensor Alarms: Check the corresponding sump or space for fluid
Equipment Fault: Look for communication or power issues

Never silence an alarm without resolving the underlying issue.

Battery & Power Backup Tips

Replace console backup batteries every 2–3 years or as needed
Check battery status indicators regularly
If using wireless sensors, replace batteries annually
Maintain your UPS or generator if used for ATG backup

Recordkeeping & Compliance

Store at least one passing leak test result per tank per month
Keep alarm response and maintenance logs
Use monthly and annual inspection checklists
Retain leak test and maintenance records for 1–5 years depending on state rules

Proper documentation isn’t just best practice—it’s required for regulatory inspections and can help avoid fines.

When to Call a Certified Technician

Persistent leak test failures
Unresolved sensor or probe alarms
Communication or power issues
Calibration, upgrades, or software reprogramming

Technicians should be certified and familiar with your specific ATG model. Many states require professional calibration or repair.
