Maretron's TLM200 is used to sense fluid levels of tanks using ultrasonic
technology. Ultrasonic, or sound waves, are transmitted via the TLM200 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 TLM200 calculates and broadcast 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 Maretron's DSM150/DSM250 color graphics displays.
The TLM200 is capable of sensing fluid levels in tanks up to 104" (2.64m) in
depth. It can be used for diesel, fresh water, waste water, black water, and oil
tanks (see the TLM100 for a lower cost solution for tanks up to 40" and the
TLM150 for gasoline
tanks). Unlike most tank senders that only work with rectangular tanks, the
TLM200 can be calibrated for irregular tank shapes so you can know the true
fluid level in your tanks.

The TLM200 is mounted directly to the top of tanks using the industry
standard SAE J1810 5-hole mounting pattern. The TLM200 can also be mounted to
tanks with threaded tank openings using an optional 1.5" NPT adapter.
Most importantly, the TLM200 is NMEA 2000®
certified so you can view any and all tank levels anywhere on the vessel when
using a compatible NMEA 2000® display. The TLM200 is
another key component of Maretron's N2KView® vessel
monitoring and control system.

Maretron’s Tank Level Adapter (TLM200) allows you to observe tank levels from
tanks up to 104" deep anywhere on the vessel where there is a NMEA 2000
compatible display. The TLM200 senses the level of the fluid in the tank using
ultrasonic technology eliminiating the need for probes into the tank, which
often foul or corrode.
