Maretron TLM150-01 Gasoline Tank Level Monitor 24" Depth

The Maretron TLM150-01 Gasoline Tank Level Monitor is a reliable ultrasonic fuel gauging system designed for boaters and anglers who demand accurate, real-time tank readings. This 24-inch depth monitor eliminates the guesswork from fuel management, allowing you to plan fuel stops with confidence and avoid running dry at the worst possible moment. Whether you're running a center console, cruiser, or offshore fishing platform, precise fuel monitoring is essential for safe, worry-free time on the water.

The TLM150-01 operates on ultrasonic technology, transmitting sound waves from a transducer mounted at the top of your fuel tank and measuring the flight time as waves reflect off the fuel surface—much like how a depth sounder reads bottom contours. This non-invasive approach means no moving parts inside the tank, no float switches to jam, and no corrosion from fuel contact. The transducer integrates seamlessly with Maretron's networked marine electronics systems, displaying fuel levels on compatible chartplotters and monitoring panels with industry-standard NMEA protocols for plug-and-play installation on modern vessels.

The 24-inch depth capacity accommodates most recreational fuel tanks found on center consoles, bay boats, and small cruisers, making it ideal for anglers and weekend boaters operating in 18 to 35-foot vessels. Installation requires minimal tank modification—just a mounting hole at the tank top—and the system works reliably in variable sea conditions without drift or calibration loss. For captains serious about fuel management and system redundancy, the Maretron TLM150-01 delivers the dependability and accuracy that separate confident boaters from those caught guessing at the pump.
