____________________________________________________________________________________________________________________________________________________________

6. MOUNTING

Below there is a diagram of placing the sensor and the base on a vehicle. Base should possibly be

placed in line of sight with respect to the FLS to ensure reliable radio communication.

The sensor base should be installed in the cabin as close as possible to the FLS or near the window

to ensure a better signal (Figure 6.1).

The sensor and the base should be oriented relative to each other for better signal, as shown in

Fig 6.2.

When installing one should consider RSSI (signal strength) from the sensor measuring it via using

a smartphone on Android OS and NRF Connect software - more details are in the article

«connection and use of a mobile phone on Android OS»)

Fig. 6.1. Installation scheme

____________________________________________________________________________________________________________________________________________________________

7. GETTING STARTED

Sensor (FLS) and sensor base are a pair of devices interconnected by a BLE UUID unique identifier

service. Base initiates a connection to the sensor, in case of connection failure makes the

reconnection.

In order to establish a connection between the base and the sensor must be they should be

located in an accessible area for each other, the base to be powered up according to the wiring

diagram, and the sensor to be in active mode (out of Sleep Mode by a magnet).

Base has the following light indication:

The FLS search mode: the blinking indicator LED

Performing the connection to the FLS: no LED illumination

In the established connection with FLS: constant LED.

In the case of connection problems (blinking indicator LED for a long time - more than 1 minute),

check sensor operation using the phone on Android OS by searching Program NRF Connect (the

article «connection and use of a mobile phone on Android OS»), perform the sensor exit of

sleeping mode procedure or change the position of the base relative to FLS, achieving the highest

level of the RSSI, watching it in NRF Connect on a phone located in the base supposed positioning

place.


____________________________________________________________________________________________________________________________________________________________

8. OPERATION MODE

The sensor measures necessary parameters (fuel level, temperature, battery voltage, RSSI, etc.)

on request from the sensor base and transmits the parameters by Escort BLE protocol via

Bluetooth Low Energy communication channel (hereinafter BLE). The period of updating the Base

data is about 30 seconds.

Sensor Base waits for a request via the RS-485 interface from external device. The response with

level and temperature data is sent via the RS-485 interface by LLS protocol in 2 … 3 ms after

request is received. Requests only with the network address recorded in the sensor base memory

are served.

The operation of Base by RS-485 has feature that, in addition to the network address where the

temperature and fuel level are transmitted, the following network address is used, for example,

if the fuel level and temperature (standard settings) are transmitted to the third network

address, will be involved also the fourth network address. The signal strength (RSSI) values in the

temperature field and the battery level values of the fuel level sensor (VBAT * 10) in the level

field are transmitted to the following network address. This feature should be taken into account

in the case of a tracker works with several sensor, because it is possible collision of network

numbers.

Set-up of the sensor can be made through the base by configurator software (full and empty level

calibration, selecting of the work mode, the setting of user password, sleep mode and reloading).

Mobile configurator or GPS-glonass tracker (terminal) can be used for set-up as well. Sensor (FLS)

supports only one connecting, so before connecting to another device, the previous one should

be disconnected.

The feature of working with the ESCORT-BTR wireless temperature sensor is that the

temperature of the sensor is transferred to the level field (fuel) in the following form: the first

digit of the level determines the sign of temperature (1 - for temperatures greater than zero, 2 -

for temperatures less than or equal to zero); then the temperature is transmitted, rounded to

tenths of a degree, for example, 1245 corresponds to a temperature of +24.5 C.

Calibration being performed for the fuel sensor (full and empty level calibration, selecting work

mode) are not applicable.

Identical to the fuel sensor software is used for work with the wireless temperature sensor.

11. UPDATING THE SENSOR SOFTWARE (FLS)

1. Pull a sensor from sleep mode by putting a magnet of sufficient power in the proximity (if

the sensor has been put to sleep mode)

2. Check the availability of BLUETOOTH LE (BLE 4.0 and higher) interface on your device in

the operating instructions.

3. Make sure the sensor is located in the reception area, and can be detected using NRF

Connect program

4. Move the sensor in a firmware update mode by rebooting it (via the mobile configurator).

5. Once the sensor is restarted the software update mode is continued for 30 seconds.

6. For convenience and extending the firmware update mode duration, one should apply a

magnet (powerful enough) to the upper part of the housing of the sensor at the time of

the restart, in which case the sensor will be in a mode of software updates until the

magnet is removed.

7. In update mode the program NRF Connect will display a new device named TD_UPDATE

12. MOUNTING TO A TANK

The most common method of mounting is fixation on self-tapping screws with a sealing washer.

It is also possible to install sensor on threaded stover nuts, welded bushings and other structural

elements. The sensor can be installed at pre-arranged locations using screws and bolts with

strength classes of at least 4.8. In this case, it is necessary to ensure the tightness of the

connection between the sensor body and the tank. For additional protection it is allowed to use

an automotive oil and petrol resistant sealant.

If it is necessary to reduce the standard length of the sensor, cut it to a length not less than 150

mm with a hacksaw, clean from the metal chips, install a centralizer, make re-calibration or

gauging. The length between the edge of metal pipes and the bottom of the tank without

centralizer should be at least 15 mm.

The following is used to prepare place for installation:

bimetallic bit of Ø 35 mm;

drill of Ø 4,8 mm

* The diameters of the holes are given for self-tapping screws, if necessary, mark places for

another fastening according to the centers of specified holes.
