Assignee: SAFRAN AIRCRAFT ENGINES
Field: Measurement (Instruments)
Classification: CPC F  B  G | IPC B  F  G

Claim 4:
5. A fuel supply circuit for an aircraft engine,
the circuit including a metering device including downstream of a fuel pumping system and upstream of injectors:
a fuel inlet,
a metering member and a cut-off member disposed in series,
a regulating valve disposed on a fuel recirculation branch, and
a computer configured for controlling the metering member and the regulating valve,

wherein at least one flow-metric sensor is disposed on the recirculation branch,
the computer being configured to implement a method comprising:
metering fuel by the metering member;
discharging into the recirculation branch fuel provided in excess by the pumping system, the discharging being performed by the regulating valve;
determining a value of a density of the metered fuel based on measurements made by the flow-metric sensor; and
controlling the metering member based on the density value.
