Preserve profits and reduce fuel shrink with AccuMeasure

AccuMeasure is a meter calibration solution that is a closed loop automated prover system to ensure flow meter accuracy and compliance to industry standards. The prover is precisely measured by a NIST traceable metrology lab to 1/100000 of a gallon, allowing incredible accuracy in testing, as well as recalibration that approaches true zero.

  • Minimize vapor loss during proving
  • Eliminate potential human error with traditional proving systems
  • Mitigate effects from temperature changes
  • Ensure precise meniscus readings, flow rates and leveling
  • Avoid costly fines, penalties, and loss of reputation

Whether a single site operation or thousands of nationwide locations, AccuMeasure is the answer for avoiding unnecessary fuel loss and shorting with weights and measure tolerances that exceed industry standards. Over time, AccuMeasure can be the difference in millions of dollars in savings.
