ABSTRACT:
A tool which is capable of measuring parameters of a multi-phase flowstream without substantially restricting the flow in the wellbore is disclosed. The tool is comprised of a plurality of extendable arms which are radially spaced around and pivotably mounted in a housing so that each arm is extendable from the housing into the flowstream in the wellbore. Various types of sensors, e.g. flow sensors, capacitance sensors, temperature sensors, etc., can be used either alone or in combination which are carried at or near the outer ends of each of the arms whereby the sensors will be deployed from the housing into the flowstream by the arms without substantially restricting the flowstream through the wellbore.
