Product Overview

This NMEA 2000 sensor monitors fluid levels using ultrasonic technology.

Ultrasonic, or sound waves, are transmitted via the TLM100 mounted at the top of the tank and the flight times of the sound waves to and from the fluid are measured much like a depth sensor. What this means for you is that there are no difficult-to-handle long probes protruding into the tank, which often foul and/or corrode.

Once the TLM100 calculates and transmits the fluid level over the NMEA 2000 network, you can observe tank levels anywhere on the vessel where there is an NMEA 2000 compatible display such as Maretron's N2KView® vessel monitoring system, or by Maretron's DSM250 / DSM410 color graphics displays.

The TLM100 is capable of sensing fluid levels in tanks up to 40" (1.02m) in depth. It can be used for diesel, fresh water, waste water, black water, and oil tanks (see TLM150 for gasoline tanks or FPM100 for deeper tanks). Unlike most tank senders that only work with rectangular tanks, the TLM100 can be calibrated for irregular tank shapes so you can know the true fluid level in your tanks.
