Product Details

The TLM100 is used to sense levels of liquid tanks using ultrasonic technology and transmit the liquid levels over the NMEA 2000 network. This allows you to observe tank levels anywhere on the vessel where there is an NMEA 2000 compatible display such as the Maretron DSM250. The TLM100 is capable of sensing tanks up to 40" (1.02m) in depth. It can be used for diesel, fresh water, grey water, black water, and oil tanks. Unlike most tank senders that only work with rectangular tanks, the TLM100 can be calibrated for irregular tank shapes so you know the true level of your tanks. The TLM100 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 TLM100 has an optional airlock for black water applications to keep the face of the ultrasonic transmitter from fouling, and 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. Best of all, the TLM100 is NMEA 2000 certified so you can view any and all tank levels anywhere on the vessel using a compatible NMEA 2000 display. The TLM100 is a key component of Maretron's N2KView vessel monitoring and control system.
