FUEL DOSING CIRCUIT AND METHOD WITH COMPENSATION OF FUEL DENSITY VARIABILITY

摘要

A fuel metering circuit (1) for a turbomachine, comprising: - 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 volumetric flow meter (9), the diaphragm (8) and the volumetric flow meter (9) being mounted parallel to the meter (6), downstream of the control valve (5), in order to determine a density of the fuel flowing in the metering circuit (1).
