Abstract
A flowmeter for use in a wellbore that has vane assemblies that deploy from a rotating segment. The vane assemblies project a variable distance away from the rotating segment, so that the flowmeter adjust to varying flow conditions. The variable distance of the vane assemblies also allows use of the flowmeter in different sized wellbores. An example flowmeter includes vane assemblies of varying length that are selectively deployed depending on operating conditions. Other vane assemblies have vane elements with a pitch that varies in response to wellbore and fluid flow operating parameters.
