Maretron TLM100 Tank Level Monitor (40 inch Max Depth) is used to sense fluid levels of tanks by using ultrasonic technology, 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, without requiring any difficult to handle long probes protruding into the tank, which often foul and/or corrode.
Once the TLM 100 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.
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).
The Mareton TLM100 can be calibrated for irregular tank shapes so you can know the true fluid level in your tanks & is mounted directly to the top of tanks using the industry standard SAE J1810 5-hole mounting pattern. The TLM100 can also be mounted to tanks with threaded tank openings using optional adapters that included both a 1.5" NPT and a 1.25" BSP adapter.
