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.• Compatibility: American Standard And European Standard Resistive Senders• Voltage: 9 To 16 Volt• Dimensions: 3.9 Inch Width X 1 Inch Height X 1.2 Inch Depth• Waterproof Rating: IP67 Waterproof• Color: Black• 16 Programmable Tank Types Including Fuel, Fresh Water, Waste Water, Live Well• Programmable Tank Number Up To 16 Per Tank Type• Programmable Tank Capacity• Works Alongside Of Analog Gauges And Can Be Used Standalone Without Analog Gauges Adapts European Standard 10 To 180 Ohm Resistive Senders To NMEA 2000(R) Network Can Be Calibrated For Any Resistive Sender Ranging From 0 To 300 Ohms Or 300 To 0 Ohms Accommodates Irregularly Shaped Tanks With 16 Point Calibration | Maretron Tank Level Adapter
