Maretron TLA100 NMEA 2000® Tank Level Adapter

The Maretron TLA100 NMEA 2000® Tank Level Adapter transforms any resistive tank sender into a networked marine instrument, giving you real-time visibility of fuel, water, and waste tank levels from any compatible display throughout your vessel. For serious anglers and cruising boaters, losing sight of tank status mid-trip can derail a fishing run or complicate a long passage—this adapter eliminates that risk by integrating your existing tank gauges into your boat's digital backbone. Whether you're monitoring fuel consumption during an offshore expedition or tracking freshwater reserves on an extended cruise, the TLA100 bridges legacy tank senders to modern NMEA 2000® networks without expensive full-system replacements.

The adapter operates by accepting the variable resistance signal from standard tank-mounted senders and converting it into NMEA 2000® protocol data that communicates seamlessly with Maretron display units and other compatible chartplotters and marine electronics. This approach preserves your existing tank sender hardware while unlocking networked data distribution—eliminating the need to physically move between multiple gauges or remember readings. The compact 7 x 2 x 10-inch footprint and lightweight 0.9-pound design allow flexible installation in engine compartments, lazarettes, or service lockers without consuming valuable cabin space. The plug-and-play connectivity reduces installation complexity, making it an efficient upgrade path for vessels already running NMEA 2000® backbones.

Boaters with single or multi-tank configurations—fuel, freshwater, blackwater, or gray water—benefit most from centralized tank monitoring, especially on vessels where tank placement makes direct visual inspection impractical. The TLA100 works with Maretron's D-series displays, N2KView software, and third-party NMEA 2000® compatible systems, ensuring compatibility with most modern marine networks. Installation requires basic electrical skills and access to your existing tank sender wiring; consult your vessel's electrical schematic and Maretron's documentation for proper integration with your specific tank sender resistance range and network topology.
