A production logging tool has a housing, a flowmeter assembly, a heating element, a drive, a clutch, and a controller. The housing has a first end attached to a wellbore string. The flowmeter assembly has a spinner exposed to fluid in the production string and a spinner shaft fixed to the spinner and extending from a rear surface of the spinner into the housing. The spinner shaft is rotatably attached to the housing. The heating element is attached to the spinner. The drive is disposed within the housing. The controller is operationally coupled to the drive and the heating element. The controller activates and deactivates at least one of the drive or the heating element to heat a volume around the spinner with the heating element or selectively spin the spinner with the drive.
