Design Criteria:


  • Replaces OEM fuel senders with rugged model
  • Custom probe length and fitting options
  • Partial or full length read
  • PC board design for accuracy
  • Buna float can extend off the bottom
  • Completely sealed electronics

Use options are numerous with the main advantage being the low cost

reading the level gauge.  A simple 12 or 24V connection works just

like the fuel gauge on your boat, car or truck. 


The unit is especially suited for off road industrial machinery that

encounter OEM fuel gauge breakdowns.  Some resistance options

are listed here.
