Abstract
A flowmeter includes an inlet for receiving a wellbore fluid therein, an outlet for discharging the wellbore fluid and a stationary outer pipe extending between the inlet and the outlet and exhibiting a first diameter for receiving the wellbore fluid in an unrestricted state. One or more movable walls are coupled within the outer pipe and circumscribe a conical flow path defining an orifice at a downstream end thereof for constricting the wellbore fluid to a restricted state. The movable walls responsive to increasing mass flow rates of the wellbore fluid to expand the orifice and responsive to decreasing mass flow rates of the wellbore fluid to diminish the orifice. At least one sensor is operable to detect a parameter indicative of the pressures of the wellbore fluid in the unrestricted and restricted states.
