2.3.9 Summation of indications
The function of
summation of the fuel volume indications
measured by a group of
DUT-E S7 sensors (up to 10 pcs.) is configured in
Settings
submenu (
Group
tab).
You may add additional sensors (Slave sensors), to the main sensor (Master sensor) that will
display the total value of the fuel volume; readings of additional sensors are to be summed up.
IMPORTANT:
For correct monitoring of readings, you must comply with the following
requirements:
1)
The calibration data
(“
Empty
”
and
“
Full
”
) and the calibration
table of the respective tank (see
) must be recorded into the profile of each sensor.
2)
The sensors’
profiles files must be saved in the memory of the Android device which is
used, in the installation folder of the Fuel Tank Monitor application.
3)
The sensors’
profiles files are not recommended to save with the names different from
names assigned by default. Because in such a case, the Fuel Tank Monitor application will
not be able to find automatically the required profile, when the connection with the
sensor is to be established.
Addition of accessible sensors to the group from
Searching
area is performed by pressing
button located to the right of the serial number of the respective sensor (see figure 21
а
).
By pressing
button in the bottom portion of
Multisensor group
area, you may add a
sensor with any serial number entered by the user.
Using
button, you may delete any respective Slave sensor from the group. However, you
cannot delete the Master sensor from the group.
The following data are displayed for each sensor from the group: serial number, current
readings of the fuel volume, data on presence/absence of active malfunctions and the indicator
of time of the latest message reception (see figure 21 b).
The total indication of the fuel volume measured by the created group of sensors is displayed
in the
Total
field, in the upper right portion of
Group
tab.
WARNINGS:
1)
In case
“
Empty
”
and
“
Full
”
calibration frequencies are not recorded in the profile of a
sensor which is added to the group, its serial number is displayed in red color. During
monitoring the total indications of the group of sensors the red-colored
No calibration
warning will be displayed for this sensor in
Indicator panel
submenu (
Group
tab).
2)
In case there are active sensor malfunctions,
(!)
red warning sign is displayed near its
serial number (see figure 21
b).
To sum up the readings of the created group of sensors during the next working session with
the Fuel Tank Monitor application, you will have to save the changed profile of the Master
sensor in the memory of the Android device which you use.
