METER CALIBRATIONS FAQs
Straightforward answers to ensure your meters perform accurately and profitably.
-
Why calibrate my meters regularly?
Over time, all fuel meters drift out of tolerance—even small deviations can cost thousands of gallons and dollars annually. Regular calibration ensures customers get what they pay for, protecting both your margin and your reputation. By keeping meters precise, you avoid disputes at the pump and demonstrate fairness to regulators and consumers alike.
-
How often should I calibrate?
While state Weights & Measures agencies perform inspections on a set schedule, best practice is to calibrate more frequently. Even minor drift can compound quickly, eroding profit before regulators catch it. By proactively scheduling calibration, you control accuracy on your terms rather than waiting for a costly inspection failure.
-
How is the calibration performed?
Our technicians use advanced equipment that replicates real fueling conditions to test and adjust accuracy. This ensures calibrations reflect how pumps actually perform for customers—not just lab standards. The process is efficient, minimizes disruption, and provides a high degree of confidence that every gallon is measured correctly.
-
What documentation do I receive?
You’ll receive a detailed ROI report showing the before-and-after results of each calibration. These reports highlight financial impact, accuracy adjustments, and compliance assurance in a clear, easy-to-use format. Having this documentation on hand simplifies audits and gives you confidence in your operational performance.
-
Does this help with compliance?
Yes. Routine calibrations align with state and federal Weights & Measures requirements, ensuring your fueling sites meet accuracy standards. Beyond compliance, this service reduces risk of customer complaints or penalties for short-delivery, while reinforcing your reputation as a trusted operator.
