Abstract
A method of determining density of a fluid within a system includes actuating a piston of a hydraulic cylinder at a target velocity. Additionally, the method includes determining differential pressure and volumetric flow rate of the fluid flowing through an orifice under actuation of the piston. The density of the fluid is determined based on the first differential pressure and the volumetric flow rate of the fluid, which is used by the system to regulate a mass flow rate of fluid within the system.
