The tank level adapter is used to adapt commercially available resistive tank senders to NMEA 2000® network. This allows you to observe tank levels anywhere on the vessel where there is an NMEA 2000® compatible display such as Maretron's N2KView® vessel monitoring system. The tank level adapter is compatible with both the American standard (240 to 33 Ohm) and the European standard (10 to 180 Ohm) resistive senders. In fact the tank level adapter can be calibrated for any resistance between 0 and 300 Ohms. Unlike most tank senders that only work with rectangular tanks the tank level adapter can be calibrated for irregular tank shapes so you know the true level of the tanks. You can also use the tank level adapter with analog gauges so you don't have to get rid of existing gauges to enjoy the advantages of digitally networked information.
