Maretron TLM100 Tank Level Monitor - 40" Depth Max - No Gas

The Maretron TLM100 Tank Level Monitor is purpose-built for serious boaters and anglers who demand real-time visibility into their vessel's liquid tank systems. Whether you're monitoring freshwater, fuel, or waste tanks on extended offshore trips or weekend runs, this ultrasonic tank level sensor eliminates guesswork and prevents costly surprises mid-voyage. The TLM100 integrates seamlessly into modern NMEA 2000 marine networks, delivering accurate tank readings to compatible displays throughout your boat's cabin, bridge, or helm station.

This monitor leverages advanced ultrasonic sensing technology to measure liquid levels without mechanical floats or invasive probes, eliminating corrosion and maintenance headaches common with traditional gauges. The TLM100 accommodates tank depths up to 40 inches, making it compatible with most recreational and commercial vessel configurations. Its wireless NMEA 2000 transmission capability means no additional wiring runs—simply connect to your network backbone and sync with any compatible Maretron display or third-party NMEA 2000 chartplotter. The compact design (7 x 2 x 10 inches, weighing just 0.65 lbs) installs easily in tight spaces, while the non-gasoline specification ensures safe operation in freshwater and waste applications.

Anglers and cruisers benefit most from this sensor's reliability during long-range trips where tank management is critical to safety and comfort. The TLM100 pairs effortlessly with Maretron's DSM250 and other NMEA 2000-compatible instruments, providing unified tank data across your navigation suite. Installation requires only a transducer mount on the tank exterior and network connection—no drilling or internal modifications. This makes it an ideal retrofit for upgrading older vessels or integrating into new-build systems where digital redundancy matters.
