Fuel metering circuit and method with compensation for fuel-density variability
A fuel metering circuit (1) for a turbomachine, comprises a meter (6), a pump (4), a control valve (5) configured to return an excess flow of fuel delivered to the meter (6) towards the pump (4) on the basis of a fuel pressure differential at the terminals of the meter (6), a diaphragm (8) and a vol...
