Maretron TLM150 Ultrasonic Tank Level Monitor

The Maretron TLM150 senses gasoline tank levels using ultrasonic technology and transmits the readings over the NMEA 2000 network, letting them be observed anywhere on the vessel with a compatible display, such as the Maretron DSM250, without a physical sender sitting inside the tank.

Unlike most tank senders that only work with one specific tank shape or depth, the TLM150's ultrasonic sensing capability handles gasoline tanks up to 24 inches in depth, and because it reads through the tank wall rather than inside it, there's nothing submerged in the fuel to foul or wear out over time.

It's built specifically for gasoline tanks rather than diesel or water, so it's worth confirming the tank contents match before ordering, since the ultrasonic calibration is tuned to gasoline's specific density and behavior. Check out the rest of our marine networking.
