Within an a/c/e/eS/gS-Series MFD, tank levels (fuel, fresh water, black water, etc.) will only be reported for tanks which have been fitted with NMEA 2000 tank level sensors. Tank levels are exclusively expressed as a percentage of full. Each NMEA 2000 tank level sensor will need to be programmed with an Instance Number and Fluid Type per procedures and/or programming equipment / software specified by the NMEA 2000 Tank Level Sensor's manufacturer. Raymarine products follow the NMEA 2000 convention that that should a single instance of a device (ex. tank level sensor, fuel rate sensor, engine, etc.) be present within a system, that its instance number will be 0. For items such as engines and tanks, where more than one such device may be installed, Raymarine's a/c/e/eS/gS-Series MFDs follow the NMEA 2000 convention that instance 0 will be assigned to the device within within the same set of devices (ex. engines, tanks, etc.) which has been installed farthest to port onboard vessel. Device instance numbers would then increment with each addition device of the same type when progressing from port to starboard. As such, should a vessel feature three engines, the port engine would need to be assigned instance 0, the center engine would need to be assigned instance 1, and the starboard engine would need to be assigned instance 2. One of the features engines interfaced via an ECI-100, is that the a/c/e/eS/gS-Series MFDs would then support engine identification to address engines having instance numbers deviating from this convention. In the absence of an ECI-100, it would be necessary to re-assign instance numbers of the engines according to procedures provided by the engine manufacturer.
Should a vessel not be fitted with NMEA 2000 tank level sensors, then the MFDs would be unable to report tank levels for individual tanks. However, should the vessel be fitted with a NMEA 2000 fuel flow sensor(s) or a NMEA 2000 engine gateway(s) reporting fuel flow rate, then the Fuel Manager feature of the a/c/e/eS/gS-Series MFDswould then be able to populate the Est. Fuel Remaining data item, which is indicative of the estimated total fuel fuel remaining within the vessel's tanks. The Total Fuel Capacity as well as full and partial fuel fill data is configured within the MFD's Fuel Manager (HOME->SET-UP->FUEL MANAGER) feature.
