Technoton DUT-E S7 Wireless Fuel Level Sensor
DUT-E S7 wireless sensor allows measuring 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 a compatible vehicle tracking unit (telematics unit) and/or any Android device.
DUT-E S7 can also be used as a “night watchman” to alert drivers on fuel theft from a vehicle’s tank, for example, when resting at night parking.
Features & Benefits:
- wireless data transfer using S7 Technology via BLE (Bluetooth 4.X Low Energy)
- operation in BLE-radio mode without pairing with receiver – simultaneous data transfer to telematics unit, smartphones, tablets with Bluetooth
- built-in battery – DUT-E S7 works without external power supply
- very low power consumption allows autonomous operation of sensor within 5 … 10 years
- explosion protection confirmed by “On the Safety of Equipment for Operation in Explosive Environment”
