Fuel level sensor with GSM and GPS DUT-E GSM is a 2-in-1 device – fuel level sensor and GPS tracker in one body. It allows fuel level measurement and GPS position tracking of trucks and other road or off-road vehicles. The sensor is also used for fuel monitoring of diesel generators and stationary cisterns/tanks.  Fuel tank monitoring based on DUT-E GSM is deployed quicker than regular telematics system – just one device is installed. Configuration of DUT-E GSM fuel sensor is possible via the Internet. Data on fuel level, fuel volume, GPS coordinates and other operational parameters of machinery are sent to online telematics server or straight to a user (e-mail, SMS) over GSM network . DUT-E GSM automatically detects and alerts fleet manager on fuel tank fill-up and fuel draining volumes. Since DUT-E GSM is an online fuel level sensor – it is a good solution for fuel-related IoT projects like smart building, smart factory, etc.
