Hi

I am using the Escort TD BLE sensor with FMB 120.

Following are the Connection settings

These are the values

These are readings from Calibration

This 1 kvants is showing in the configuration. What does that mean is the CNT values from the sensor, and **how to formulate this for the calculation** of fuel in litres.

Looking forward to the solution

Hello @mgr,

I hope you are doing well. The preset for the Escort Fuel Sensor appears to be correct. However, it seems that the BLE Fuel Sensor has not been connected to the tank. I recommend connecting it so you can compare and verify the device readings, as accurate values will not be displayed unless the sensor is actively measuring from the tank.

Hope this helps.

Best regards,  
Patrick S.

Yes, you are right. The sensor is not connected to the Tank.  
But after connecting to Tank and with this Calibration, what is the formulated calculation for the backend?
