Тема: How connect several Eurosens Dominator RS sensors to RS232 interface
We all know these issues of fuel monitoring:
1. Many vehicles have several fuel tanks
2. Many popular GPS trackers have only RS232 interface
3. RS232 interface is made for only 1 device connection
So, you can't connect more than 1 precise fuel level sensor with digital output.
Usually some extra devices are used - external summators etc.
We can provide more effective solution, because Eurosens Dominator RS have both RS232 and RS485 interfaces onboard, as well as K-Line.
You can use one of this schemes:
When tanks have different volumes obviously you need to enter tank calibration tables in each sensor. So master-sensor can calculate a total sum of fuel volume and provide to RS232.
GPS tracker will see our FLS system with master sensor as one single tank of big volume.
Our we can provide data for each tank independently, but some changes in FLS data procotol must be done from GPS tracker side.
