The expandable meshed component transitions from a compressed configuration to an expanded configuration at a target height in the Christmas tree valve. A production wing valve of the Christmas tree valve is opened. The swab valve is closed. The untethered measurement device is retrieved from the Christmas tree valve through the swab conduit.
