DUT-E S7 wireless sensor allows to measure current fuel volume and its changes in a fuel tank. DUT-E S7 is used as a part of vehicle telematics system (GPS vehicle tracking system) and provides reliable information on remaining fuel volume, fuel tank fill-up and draining volumes and helps fleets to set up clear fuel accounting and prevent fuel theft from vehicle’s tank. DUT-E S7 wireless fuel level sensor is also used for fuel level monitoring in stationary tanks.
Wireless data transfer is carried out using S7 Technology via BLE channel. BLE signal from DUT-E S7 can be received by compatible vehicle tracking unit (telematics unit) and/or any Android device.
DUT-E S7 can also be used as a “night watchman” to alert driver on fuel theft from vehicle’s tank, for example, when resting at night parking.
