Good day. Thank you for the question.
If you are referring to the server used in page https://wiki.teltonika-gps.com/view/Technoton_DUT-E_S7_Fuel_Level_Sensor#Data_on_the_telematics_server , its only an example of the server interface and where to look for the information in the server. The server is fully integrated with Teltonika FM devices in order for the data to be received and analyzed. You may use any server that is integrated with Teltonika devices in order for you to get the data of the Technoton DUT-E S7 Fuel Level Sensor
Please let me know if this helps.
