A buffer insert is emplaceable within a memory gauge system buffer chamber. The buffer insert includes a reduced diameter, extended inlet conduit that attaches to the buffer chamber opening. The inlet conduit employs capillary repulsion to impede entrance of wellbore fluid into the buffer chamber. The inlet conduit forces infiltrating fluids to enter proximate the top of the chamber rather than its bottom. The insert further includes an extended curled capillary allowing restricted fluid communication between the chamber and the transducer. Entrance to the curled capillary is located proximate the bottom of the buffer chamber, thereby forcing infiltrating fluids to travel downward through the more viscous silicon oil. Testing has shown the system of the present invention to greatly reduce contact with the transducer components by infiltrating wellbore fluids.
