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 or iOS 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.

DUT-E S7 advantages
ь ”BLE-radio” operation mode – signal is transmitted automatically to all Receivers in the range.
No device pairing procedure required.
ь No cable – no wire damage possible, increased resistance to vandalism.
ь Thermal correction – compensation of thermal expansion/compression of fuel in tank.
ь No cable – quick and simple installation of telematics equipment and its configuration.
ь No external power supply – fire- and explosion- safety of the sensor.
ь Storing DUT-E S7 profile outside the sensor – protection against unauthorized changes to settings.
ь In-built battery lifetime - 5 years.

Fuel tank monitor mobile app
In addition to telematics unit, the data from DUT-E S7 can be received to
a smartphone or tablet. To see the data, Fuel tank monitor app should
be downloaded from Google Play or App Store (search “Technoton”).
All settings made in the application are not written to the sensor, but
only saved in the memory of the smartphone/tablet. DUT-E S7 settings
cannot be changed by tampering with its electronics!

Summary
Wireless fuel level sensor
ь Due to absence of cable, DUT-E S7 installation is quicker and eliminates risks of accidental or
purposeful damaging of cables. Embedded battery ensures sensor operation over 5 years.
ь Ex certificate allows using DUT-E S7 in hazardous zones of 0, 1 and 2 grade – fuel tankers,
fuel storages, gas stations.
ь DUT-E S7 probe length is easily shortened or extended up to 3,000mm during sensor installa-
tion to tank. On backorder probe length can be 6,000mm (delivered sectional).
ь BLE-radio operation mode allows data sending to telematics unit, smartphone and cab dis-
play simultaneously over Bluetooth 4.X.
ь Fuel tank monitor app allows driver to get real-time data: remaining fuel volume in tank,
refilling volumes at gas station, alarms on fuel theft (“night watch” feature).
