Advanced Ultrasonic Tank Level Monitoring for Marine Vessels
The Maretron TLM100 Tank Level Monitor provides precise fluid level measurement for tanks up to 40 inches (1.02 meters) in depth. Utilizing advanced ultrasonic technology, this sensor eliminates the need for intrusive probes that can corrode or accumulate debris. Designed for seamless integration into an NMEA 2000® network, the TLM100 ensures real-time tank monitoring from any compatible display on your vessel, making it an essential tool for reliable fluid management.
Reliable Ultrasonic Sensing Technology
Unlike traditional tank senders that rely on mechanical floats or probes, the TLM100 uses ultrasonic sound waves to measure fluid levels accurately. By transmitting and receiving sound waves from the top of the tank, this sensor provides precise readings without direct contact with the liquid. This minimizes maintenance, prevents fouling, and enhances long-term durability, especially in harsh marine environments.
Versatile Tank Compatibility
The TLM100 is designed to work with various tank types, including diesel, fresh water, waste water, black water, and oil tanks. Additionally, it supports calibration for irregular tank shapes, providing accurate readings even in non-rectangular configurations. For gasoline tanks, the TLM150 is recommended, while deeper tanks require the TLM200.
Easy Installation and Universal Mounting
The TLM100 is engineered for straightforward installation, mounting directly onto tank tops using the industry-standard SAE J1810 5-hole pattern. Optional adapters are available for threaded openings, including 1.5" NPT and 1.25" BSP fittings. Additional accessories, such as an airlock for black water applications and a focus tube for boats with planing hulls, further enhance functionality and adaptability.
Seamless NMEA 2000® Integration
Certified for NMEA 2000® compatibility, the TLM100 enables vessel-wide monitoring through any compatible display, such as the Maretron DSM250. When integrated with the Maretron N2KView® system, it becomes a crucial component of a comprehensive vessel monitoring and control solution, ensuring real-time awareness of tank levels from any location on board.
