Key technology research and practice in fuel dispenser metrological calibration

This paper conducts research on the key technologies involved in the verification of fuel dispensers. It systematically analyzes the scientific selection methods for metrological standards, with a particular focus on the mechanisms through which temperature affects verification results and corresponding control strategies. The study further elaborates on the full-process operational specifications, encompassing nameplate inspection, interlock function verification, software identification checks, indication error verification, as well as repeatability and payment amount error testing. This work provides technical support for establishing a precise and efficient regulatory system for fuel dispenser metrology.
