1.4.2 Data composition of DUT-E S7 output message
DUT-E S7 wireless fuel level sensor transmits data by means of S7 Technology , without
integration with receiving devices and without acknowledgement of data reception.
The data in the form of Advertising packets are transmitted automatically with 5 s periodicity
in the continuous data transfer mode. The structure of the data packet transmitted by
DUT-E S7 is provided in figure 7.
