When the EMU-1 is configured for fluid level you have the option to select the type of fluid you wish to monitor. The available options are:
- Fresh water
- Waste water
- Live well water
- Black water (sewage)
These options are defined by the NMEA in the Fluid Level PGN (127505) and therefore cannot be altered by us. If you wish to monitor fluid that isn't listed here, you can choose one of the available options so long as you are aware that it will show on a display as the defined value listed above because the receiving device will have been designed to understand the same defined PGN.
For example choosing 'Fresh water' to monitor drinking water will show on a display as 'Fresh water', not drinking water.
