Using Eurosens Display and several fuel level sensors to show total fuel volume in the tanks.

We recommend to use the latest configuration software and update firmware to an actual version for all devices.

Connection diagram. Two fuel level sensors installed in 2 tanks. They are connected to Eurosens Display RS and to GPS tracker by RS485 bus . Display will sum up fuel volume in both tanks and show total.

Setting up fuel level sensors. Choose type of interface – RS485. Both sensors must have different address in RS485 network (for example – 2 and 3), so we incheck “Ignore” option in fuel level sensor address menu.

Setting up the Display: It works in adder mode by RS485 interface. Since we don’t have to send data to external system – choose K-line output interface , to not interfere with RS485 internal communication.

Open the Adder section of Eurosens Display configurator. Set Ignore option to Adder address (since we have only 1 adder in RS485 bus). Choose Adder mode : Omnicomm. There is only one device is able to poll other devices in RS485 network and we already have GPS tracker which does it. That means, we have to switch Display in Passive mode. Choose option “Passive adder”. Then enter all sensors to be added in the Adder list. To add sensor we must enter its address in RS485 network. Zero address means sensor is not used. Also we have to set fuel tank volume, minimum and maximum value from sensor (for empty and full tank). These data must be same with sensor settings.

As a result, we can see now fuel volume in each tank and total volume on the Eurosens Display screen.

Configurator of GPS tracker will show us sensors values too. Note, that Eurosens Display shows fuel volume in liters. To convert GPS tracker data to liters we have to add in GPS tracking software simple tank calibation table consist from 2 points : empty and full for every sensor:

Sensor value N=1   Fuel volume =0

Sensor value N=1023   Fuel volume =tank volume.
