SAE 5-bore international flange. 12/24V compatible. IP65 watertight. Stainless steel body.Level sensors are programmed to indicate the use of the tank (ex. black/grey/freshwater - fuel) and, if communicated when ordering the items, the volume that will be expressed in litres instead of in percentage. In case more than one tank for the same liquid is present onboard, the order shall also indicate the numbering of the tanks (ex. 1 - 2 - 3).All sensors can be reprogrammed (e.g., black / grey / white water - fuel) and the tank capacity can be added using the NMEA 2000 programmer (type our article 27.165.00).
