2.3 Wireless transfer of sensor indications to the Android
device
For wireless monitoring of DUT-E S7 by means of
, first, download the Fuel Tank
Monitor application on your smartphone/tablet from
(search request “Technoton”)
IMPORTANT:
1)
To eliminate connection failures between the DUT-E S7 and the Android device, you
need to make sure that there are no sources of electromagnetic interference near your
working place (radio telephones, video signal transmission units and other wireless
devices operating within 2.4 or 5 GHz frequency bands, as well as running electric
motors, powerful transformers and switching equipment, welding equipment, high-
voltage lines etc).
2)
The maximum allowed distance between the DUT-E S7 and the Android device
depends on the quality of the Bluetooth connection of the Android device. To assure
the stable data transmission, it is recommended that this distance should not exceed
20 m.
2.3.1 BLE-module activation
WARNING:
The transfer of
indications to the Android device is possible
only after activation of the sensor BLE-module.
DUT-E S7 has the following modes of operation determined by the status of its BLE-module:
•
“
Storage
”
—
the sensor is in this mode from the moment it is manufactured.
The BLE-module of DUT-E S7 is disabled, no data transmission at all.
•
“
Manufacturing
”
—
in this mode, the BLE-module of DUT-E S7 is activated for data
transmission only for the period of the sensor testing or checking its operability with
Fuel Tank Monitor application.
To activate this mode, you need to apply the magnetic key (see the
) for
1 s
to the cap of the sensor
“
head
”
(see figure 9 a).
4 h
later or after another touching the
sensor cap by the magnetic key, the BLE-module of DUT-E S7 again becomes inactive.
•
“
Operating
”
—
this mode is enabled, when the sensor is mounted in the tank of a
or in a fixed tank. In this mode, the BLE-module is fully enabled, without the
possibility to return to the inactive state. After that, DUT-E S7 is ready to transmit data
by means of S7 Technology throughout its service life.
To activate the
“
Operating
”
mode, you need to bridge the tubes of DUT-E S7 measuring
probe with a small screwdriver and
simultaneously
apply the magnetic key to the
cover of the sensor
“
head
”
for
1 s
(see figure 9 b).
