1.1 Introduction
Congratulations on your purchase of the Maretron Tank Level Monitor (TLM150). Maretron has
designed and built your monitor to the highest standards for years of reliable, dependable, and
accurate service.
The TLM150 is used to sense levels of gasoline tanks using ultrasonic technology and transmit
the gasoline levels over the NMEA 2000

network. This allows you to observe gasoline tank
levels anywhere on the vessel where there is an NMEA 2000
®
compatible display such as the
Maretron DSM250. The TLM150 is capable of sensing gasoline tanks up to 24” (0.61m) in
depth. It must be used only for tanks containing gasoline. Unlike most tank senders that only
work with rectangular tanks, the TLM150 can be calibrated for irregular tank shapes so you
know the true level of your tanks. The TLM150 can be mounted on tanks with a SAE J1810 5-
hole mounting pattern, or to tanks using 1.5” NPT or 1.25” BSP threaded openings via
available adapters. The TLM150 has an optional focus tube to allow use on boats with planing
hulls when the vessel spends a significant amount of time with the bow pitched up.
The Maretron TLM150 is designed to operate within the harsh demands of the marine
environment. However, no piece of marine electronic equipment can function properly unless
installed, calibrated, and maintained in the correct manner. Please read carefully and follow
these instructions for installation, calibration, and usage of the Maretron TLM150 in order to
ensure optimal performance.

1.2 Gasoline Tanks
The TLM150 is ONLY intended for use in tanks containing gasoline. Do not use the TLM150
in tanks containing diesel fuel, water, oil, or other liquids. Use in tanks containing other liquids
will result in inaccurate readings.
