FIELD: measuring equipment.
SUBSTANCE: invention can be used in fuel dosing apparatuses for turbomachines. The fuel dosing circuit for a turbomachine comprises a dosing apparatus, a pump, a control valve, a diaphragm, and a volumetric flow meter. The pump is configured to direct the fuel flow to the dosing apparatus. The control valve is configured to return the excess fuel flow supplied to the dosing apparatus into the pump in accordance with the fuel pressure drop at the end points of the dosing apparatus. The volumetric flow meter is configured to determine the volumetric fuel flow passing through the diaphragm. The diaphragm and the volumetric flow meter are installed in parallel with the dosing apparatus in a bypass channel downstream from the control valve in order to determine the density of the fuel circulating in the dosing circuit. Disclosed are a turbomachine containing a fuel dosing circuit and a method for dosing fuel.
EFFECT: increase in the accuracy of dosing the fuel flow.
