The article investigates the possibility of carrying out verification of volumetric liquid meters at the place of operation
and presents the procedure for carrying out such verification. The issues of metrological support of measuring instruments
(MI) of the aircraft refueling service are considered. The data on the verification of measuring instruments of the aircraft refueling
service in the EU member states are presented.
