A logging tool for use downhole includes sensor modules that monitor fluid flow in a wellbore. The sensor modules are disposed on flexible arms that project radially outward from the logging tool, so that the modules are located at discrete radial positions in the wellbore. The sensor modules include a flow sensor, an optical sensor, and a fluid conductivity sensor. The rate and type of fluid flowing in the wellbore can be estimated due to employing the different sensor types. A location sensor estimates the radial location of the modules so that a flow profile of the flowing fluid can be obtained.
