Technician Checking Fuel Pump


Get my drift? Meter drift explained.

By Caleigh Millette, Warren Rogers Associates, 2020


What is meter drift? How can it be fixed?

Meters tend to drift when they are out of alignment or off center, usually in the positive direction. This results in more fuel being pumped out than what the customer paid for, which can lead to considerable money loss for your business over time. Meter drift can become more serious as the dispenser ages, though all dispensers may drift at their own rate. As a meter naturally wears down, more fuel passes through than expected.

Flow meters measure the amount of fuel being dispensed and can show leaks through data. Because of this, flow meters are essential in detecting problems and preventing harm to public and environmental health and safety. For flow meters to perform properly and accurately detect problems as they arise, they need to be well-maintained and calibrated when necessary.

Conducting calibrations on your meters whenever necessary can prevent them from performing inaccurately, thus preventing fuel loss — and money loss. Most of the time, calibrations are required at least once a year. A meter that cannot be effectively calibrated may need to be replaced or repaired.
