Why Should I Have My Meters Calibrated?

Many station owners and operators ask this question because they believe that the testing periodically completed by a State weights and measures official is all that is needed. Unfortunately, this belief can lead to profit loss, fuel shortages to customers, or poorly maintained meters that may require costly repairs in the future. And since the State may not visit a site for several years, there is time for meters to become increasingly inaccurate, further shorting the customers in fuel, or worse, giving away more fuel. 


To make matters worse, if the State indeed visits, they will inform you of a fuel shortage incident, however, they are not required to issue a violation if the site is giving away small amounts of fuel. The only way to avoid these problems is to have all meters calibrated on a regular basis before any such issues arise. This low cost, preemptive measure can ensure accurate fuel delivery and increase overall compliance.

Why Should I Have My Meters Calibrated?

The smallest incremental change in a meter can result in losses that may grow exponentially with each passing day. The chart below reflects the importance of meter calibration in the detection and prevention of fuel loss. The figures shown are based on meters that are off by only four (4) cubic inches (cu in) per five-gallons.


If 8 out of 24 meters at a station with average throughput are inaccurately calibrated, they stand to give away 1,384 gallons of gas over 12 months. At an average price of $3.10/gallon (Jan. 2015), that equals a loss of $4,290! Can you afford to absorb a loss this great each year?
