Senders can be easily cut to length to suit tank depths from 10 to 80 inches (250mm to 2 meters) and fit in most fuel tanks using the industry standard SAE 5 bolt fitting. They can also be threaded into a 1-1/4in BSP hole using the OSS-3261 mounting ring(sold separately). The Tank Sender can store an alphanumeric tank name and tank shape calibration data so that displays on the network can show the tank name and its remaining capacity in Liters, US Gallons or in Gallons.

This sender comes complete with a full installation and operation manual, tank gasket and combined power and signal cable. It draws less than 50 milliamps of power from the NMEA2000 network and requires no additional wiring.
