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

The TLM100 Ultrasonic Tank Level Sensor revolutionizes liquid level monitoring on marine vessels by providing accurate, real-time data through advanced ultrasonic technology. Designed for seamless integration with the NMEA 2000 network, the TLM100 allows boaters and marine professionals to effortlessly track tank levels from any location on the vessel using compatible displays like the Maretron DSM250.

Advanced Ultrasonic Technology

Utilizing cutting-edge ultrasonic sensors, the TLM100 delivers precise measurements of liquid levels up to 40 inches (1.02 meters) in depth. This technology ensures reliable readings across various tank types, including diesel, fresh water, grey water, black water, and oil tanks. Unlike traditional tank senders limited to rectangular shapes, the TLM100 can be calibrated for irregular tank geometries, providing accurate levels regardless of tank design.

Seamless NMEA 2000 Integration

The TLM100 is NMEA 2000 certified, facilitating effortless integration into your vessel’s existing monitoring system. By transmitting liquid level data over the NMEA 2000 network, the TLM100 enables you to view tank levels on any NMEA 2000 compatible display device, such as the Maretron DSM250, ensuring you stay informed about your vessel’s fuel and water status from anywhere on board.

Versatile Compatibility and Installation

Designed for versatility, the TLM100 can be mounted using several standard patterns and threaded openings:

• SAE J1810 5-Hole Mounting Pattern: Compatible with tanks featuring the SAE J1810 standard for straightforward installation.
• Threaded Openings: Fits 1.5" NPT or 1.25" BSP threaded tank openings with available adapters, accommodating various tank types on your vessel.

Installation is user-friendly, allowing for quick setup and minimal downtime, so you can focus more on enjoying your time on the water.

Customizable for Any Tank Shape

The TLM100’s ability to calibrate for irregular tank shapes sets it apart from conventional tank monitoring solutions. This feature ensures accurate liquid level readings even in uniquely shaped tanks, providing peace of mind that your tank levels are correctly monitored regardless of tank design complexities.
