Maretron TLM100 Ultrasonic Tank Level Monitor

The Maretron TLM100 Tank Level Monitor senses levels of liquid tanks using ultrasonic technology and transmits the liquid levels over an NMEA 2000 network. It is designed for boaters who want to observe tank levels anywhere on the vessel where there's an NMEA 2000 compatible display, such as the Maretron DSM250.

Capable of sensing tanks up to 40" (1.02m) in depth, this monitor works for diesel, fresh water, grey water, black water, and oil tanks. Unlike most tank senders that only work with rectangular tanks, the TLM100 can be calibrated for irregular tank shapes so you know the true level of your tanks, mounting via SAE J1810 5-hole pattern or 1.5" NPT/1.25" BSP threaded openings with available adapters.
