Questions and answers

Can I connect multiple fuel level sensors to one tracker?

Yes, RS-485 allows you to connect multiple sensors to one tracker, provided that each sensor is assigned a unique network address.

Is it necessary to calibrate the sensor?

The BI FLSensor v.8 sensor must be calibrated after trimming. The calibration process is done “dry” and only for an empty tank.

Does the sensor support saving the calibration table?

Yes, the sensor allows you to save the taring table in memory – in this mode, the sensor will immediately give values ​​in liters.
