Purpose of DUT-E S7
Operating principle:
has an inbuilt
Bluetooth low energy module (BLE-module)
which, due to a special data transmission algorithm, enables the sensor operation with ultra-
low power consumption. The BLE-module transmitter switches on automatically once in 5 s to
transmit the current indications
. Such a mode of operation enables the sensor to operate
completely independently during no less than 5 years without using any external power
sources; power is supplied only from the inbuilt battery.
Data from DUT-E S7 can be received at a distance of up to 50 meters by unlimited number of
various receiving devices (
, Android-smartphones/tablets etc.), which are
equipped with Bluetooth 4.X module.
Application areas:
DUT-E S7 may be applied both independently, and within the
(it may operate without using services of a
) for wireless monitoring the fuel
volume:
1)
(see figure 4 a).
2)
In fixed tanks (employed in oil products storage facilities, boiler equipment, diesel
generators sets etc.)
(see figure 4 b)
.
