9. A method for measuring a flow of a wellbore fluid, the method comprising:
receiving the wellbore fluid at an inlet of a flowmeter having a stationary interior wall defined therein;
flowing the wellbore fluid through a flow path defined through a plurality of movable walls disposed within the stationary interior wall;
rotating at least one adjustment beam supported on a lateral end of one of the plurality of movable walls and engaged with a threaded section on an adjacent one of the plurality of movable walls to drive the lateral end laterally along the threaded section and thereby adjust a diameter of the flow path;
detecting at least one parameter of the wellbore fluid indicative of a pressure of the wellbore fluid in the flow path; and
determining a flow rate of the wellbore fluid based on the at least one parameter of the wellbore fluid.
