The wireless fuel level sensor is the model DUT-E S7. Firstly, it provides information on current fuel volume and the changes in the fuel tank such a fill up and draining volumes. So, it assists businesses with accounting for fuel and preventing fuel theft from the vehicle’s tank. The DUT-E S7 is part of the vehicle telematics system. This comprises of the GPS Vehicle Tracking System which provides this reliable information. Also used for fuel level monitoring in stationary tanks.
Data is wirelessly transferred. Using the S7 technology via Bluetooth Low Energy Channel (BLE). The Bluetooth signal can be received by compatible vehicle tracking unit and/or any Android Device. It also can be used to alert driver on fuel theft from the vehicle’s tank when parked for the night.
Exciting features of the wireless fuel level sensor include:
- Wireless data transfer using S7 Technology via BLE (Bluetooth 4.X Low Energy)
- Operation in BLE Radio mode without pairing to receiver – allowing data transfer to telematics units, smartphones, tablets with Bluetooth
- Built in Battery and no Cables
- Low Power consumption allowing autonomous running of sensor to between 5 and 10* years *(depending on ambient temperature)
- Shortening/extending the measuring probe length
- Bottom Spring for higher rigidity of mounting into tank
- Screen filter for probe protection from water and mud in tank
- Self-diagnostics quality check for sensor operation
- Automatic Temperate Correction
- Full set of Mounting Accessories
- Explosion Protection
Fuel Tank Smartphone App
The Fuel Tank Smartphone App for the DUT-E S7 is available from Google Play. Firstly, the driver can check volume refills, how much is left in the tank and alarms if any is stolen. Plus, it allows fleet managers to record fuel volume in the tank when transferring the vehicle from a driver to another.
Fuel Tank App Features include
- Information about the sensors including serial number, firmware version and address within S7 network
- Saving profile from other android devices
- Sensor Calibrations on whether tank is full or empty
- Fuel Tank Calibration Table
- Self-Diagnostics information
- Data logging from DUT-E S7 Fuel Level Sensor
