For our client, we designed and developed a plug-and-play device that measures fuel level and works as a digital trip computer for vehicles that run on LPG. We placed additional sensors on the LPG fuel tanks to determine the fuel level. We also developed an electronic card that could be inserted into the OBD socket to collect data. With this handy equipment, information could be gathered from the gas sensors located in different parts of the vehicle, and the fuel level sensor could be monitored. Thus, the vehicle brain could be visualised by the client.
