we have an installation of the fmb 640 with the ul212 fuel level sensor in a truck.
Status of the installation:
-The tank has already been calibrated;
-connections are well made;
-The system worked perfectly in a period of 5 months;
-Gps detects constant refueling on the wialon platform as shown in the picture:
Interventions made to resolve the error:
-We reinstalled the ul212 sensor on the tank surface;
-Remove the ul212 sensor;
-Remove the wiring and connections;
But the problem persists.
