== '''<big>CNT. What happens when you calibrate a sensor?</big>''' == | |||
After you have cut or extended the sensor tubes, you should calibrate it, that is, set the new '''Full''' and '''Empty''' calibration values. You can do this from the '''Settings''' menu on the sensor's main screen. | |||
[[ | [[File:SettingsPageAndroid.png|frameless]] | ||
The sensor's raw data - current level or CNT - changes according to how much fuel is inside its tubes. | |||
Then, CNT is compared with the values Empty and Full. | |||
If the '''tubes are empty''' and “'''CNT (1) ≈ calibration value Empty (2)'''”, level 1 '''(3)''' will be displayed.<gallery mode="nolines" widths="400" heights="750"> | |||

Thus, '''CNT''' should increase as the sensor tubes fill with fuel. It should change from a value close to the '''Empty''' calibration value to the '''Full''' calibration value. | |||
<big> | [[File:TankEmptyFull.png|frameless|512x512px]]<blockquote><big>During sensor calibration, the current CNT is stored as a Full calibration value (if you pressed the '''Full''' button) or as an Empty calibration value (if you pressed the '''Empty''' button).

Initially, the sensor is calibrated to its original length. '''After you have cut or extended the tubes, you should recalibrate it.''' Set the new CNT values that the sensor has when its tubes are empty or filled with fuel. | |||
Therefore you should: | |||
* Insert the plastic centralizer provided into the tubes | |||
[[File:Centralizer.png]] [[File:Centralizer-Centrator.png|512x512px]] | |||
* Fill the tubes with fuel by covering the drain holes with electrical tape and turning the sensor upside down or immersing the sensor in fuel so that the fuel reaches the flange of the sensor (the drain holes are open).

An alternative calibration method is calibration without fuel. | |||
In this case, make sure that the sensor tubes are empty and there is no fuel in them, but the centralizer must be inserted into the tubes. Leave the '''"Calibrate without fuel"''' switch '''(1)''' active (green) and press '''"Calibrate" (2)''' .

</gallery> | </gallery>If you calibrate the sensor without fuel, the operating range may change slightly. | ||
There are two measuring ranges: | |||
* | * From 1 to 1023 | ||
* | * From 1 to 4095 | ||
Sensor does not sends level 0. If there is no fuel, level 1 is level sent. | |||
''' | '''The sensor itself does not know what fuel will be used, so when calibrating without fuel the "Empty" value is set based on the current (CNT), the "Full" value is set by a formula and, depending on the length of the tubes and the final fuel used, the range may change .''' | ||
''' | '''For example, when the tank is full, the sensor will show 3843 instead of 4095, or it is possible that when the tank is 98% full, the sensor will already display the value 4095.''' | ||
''' | '''If possible, we recommend calibration with fuel. If tank calibration is not planned or is impossible, then calibration with fuel is a mandatory procedure.''' | ||
== '''<big> | == '''<big>When and how to choose a range - 1023 or 4095?</big>''' == | ||
''' | The '''measuring range 1...1023''' is generally recommended for sensors '''shorter than 500 mm'''. The '''measurement range 1...4095''' is recommended in other cases. | ||

To prepare the tank you should: | |||
* Empty the tank, clean and dry if necessary | |||
* '''Remove fuel vapors and air from the tank''' (especially for a gasoline tank, but in the case of a diesel engine, this procedure should not be neglected, since gasoline could be added to the diesel); to do this, you can heat water to boiling point and direct the resulting steam into the tank or use carbon dioxide so that it displaces fuel vapors and air; ensure that any open flame sources are sufficiently far away from the fuel tank[[File:Removing_fuel_vapors.png|frameless|496x496px]] | |||
* '''Find the geometric center of the tank and drill a hole''' in it using a '''ø3mm''' drill bit. Then, using a piece of stiff wire, examine the tank for the presence of partitions in it[[File:Choosing_a_location_for_installing_the_FLS.png|none|thumb|512x512px|'''<big>Choosing a location for installing the FLS</big>''']][[File:Little_hole_drilling.png|none|thumb|511x511px|'''<big>Drilling the tank and subsequent examination of the tank for the presence of partitions</big>''']] | |||
* If the space inside the tank in the selected location is free, '''drill a ø 35 mm hole''' using a bimetallic bit; When drilling, keep the bit tilted slightly to prevent the cut section from falling into the tank. Use a magnet to catch chips and prevent them from getting into the tank.[[File:Angled_drilling.png|none|thumb|512x512px|'''<big>Drilling a hole at an angle</big>''']][[File:Removing_metal_part.png|none|thumb|512x512px|'''<big>Removing a drilled disc</big>''']] | |||
* If it is impossible to install the sensor in the geometric center of the tank, try choosing another location as close as possible to the geometric center of the tank; this point should coincide with the place where the height of the tank is maximum. This way you reduce the risk and amplitude of level fluctuations associated with fuel movement while driving. | |||
=== '''<big>Why should the sensor be mounted in the geometric center of the tank?</big>''' === | |||
'''The highest point must be chosen so that the sensor can measure the level of all the fuel inside the tank without any blind spots.''' | |||
The fuel level readings from a sensor installed in the center of the tank will be least affected by movement and fuel overflow in the tank. | |||
If it is not possible to install the sensor in the center of the tank, consider installing two sensors diagonally at two corners. When fuel flows to one side of the tank, the level on the corresponding sensor will rise, and on the opposite side, the level will correspondingly decrease, while the average level will remain unchanged. | |||

<blockquote>'''Attention:''' Before starting the calibration, the vehicle/fuel tank must be positioned flat in relation to the horizon, i.e. on a level surface without a slope.</blockquote>If the tank has an irregular geometric shape, the sensor must be installed at the maximum depth of the tank, closer to the geometric center. | |||

==== '''<big> | ==== '''<big>When installation in the center is impossible - two or more FLS.</big>''' ==== | ||
To increase accuracy and reduce level fluctuations, install two sensors in one tank. This solution is mainly used in tanks with a capacity of more than 600 liters and having a length of 1500 mm. Sensors must not be installed close to the walls of the tank. | |||
Also, two or more sensors should be installed if it is not possible to install the sensor in the center of the tank and (or) the tank has an elongated shape, i.e. The length of the tank is significantly greater than its height. | |||
[[ | [[File:Two_sensors_installed_diagonally.png|none|thumb|654x654px|'''<big>Two sensors installed diagonally</big>''']] | ||
'''Note.''' Installing a single sensor in an elongated tank will allow you to detect drains and refills. But increased level fluctuations while driving may not allow the monitoring platform to correctly read fuel consumption. Therefore, installing two sensors is preferable. | |||

=== '''<big> | ==== '''<big>Ladder shape tank's tank calibration</big>''' ==== | ||
When calibrating, it is necessary to create two tables, one for "'''FLS 1'''" and the second for "'''FLS 2'''" | |||
' | Let's assume that the calibration step is 10 liters. | ||
At the beginning of calibration, when the fuel is in the "'''Red Zone'''", the level changes will only occur on "'''FLS 2'''", so we directly add calibration steps of 10 liters to the table for "'''FLS 2'''". | |||
When the fuel is in the "'''Yellow Zone'''" changes will occur on both "'''FLS 1'''" and "'''FLS 2'''", during this period we record changes in both tables with half a step, that is, we also fill in 10 liters, but we record 5 liters in the table of each sensor. | |||
When the fuel is in the "'''Green Zone'''" the changes will only occur on "'''FLS 1'''" so we directly add calibration steps of 10 liters to the table for "'''FLS 1'''". | |||
On the platform "'''FLS 1'''" and "'''FLS 2'''" are started as separate sensors with their own tables and then a third virtual sensor is created with the sum of liters for two sensors, an example of starting two FLS on the platform is shown [https://docs.google.com/document/d/14p9GYmY0D1Wjz0ZfJXO-soVfxRBP7EiY7TgibD6vmZQ/edit?usp=sharing in this instruction.] | |||

=== '''<big>Preparing the sensor tubes</big>''' === | |||
Before calibrating the sensor, you should '''determine the future length''' of the measuring tubes in accordance with the height of the tank and '''cut or extend them'''. The length of the tubes should be calculated according to the following formula: | |||
'''L = H - 15 mm,''' | |||
where L - tubes length after changing the length | |||
and | |||
H - height of the tank at the installation point.<blockquote><big>'''ATTENTION!!!''' '''The minimum length''' of the tubes should not be less than '''15 cm (150 mm)'''. Otherwise, it will most likely not be possible to obtain adequate graphics. The maximum length of the tubes can reach '''6m.'''</big></blockquote> | |||

[[File:Measuring_tubes_length.png|none|thumb|942x942px|'''Measuring the length of tubes''']] | |||
Use a hacksaw to cut the tubes. When sawing, be careful not to damage the connection of the tubes to the circuit board inside the sensor head and to prevent metal shavings from falling into the tubes. | |||
[[File:Cutting_the_tubes.gif|none|thumb|600x600px|'''Cutting the tubes''']] | |||
'''Avoid getting shavings inside the tubes - this may lead to a short circuit in the sensor; if this happens, blow the tubes with compressed air through the drainage holes under the sensor flange.''' Sand the edges of the tubes with sandpaper to remove any burrs or irregularities. | |||
To extend sensor tubing, use a collet extension and an additional tube. | |||
[[File:Collet_connection.png|none|thumb|875x875px|'''Collet connection''']] | |||
[[ | |||
[[ | Inner nuts (yellow elements) are used to connect the inner tubes. Once they are installed and the studs are screwed into them, the tubes do not have to touch each other, but try to get them as close to each other as possible.. | ||

Once the length sensor has been adjusted to the height of the tank and the sensor has been calibrated, you need to install it in the tank. | |||
Install the sensor into the tank of the installed tube in the previously drilled hole ø 30-35 mm. Make sure '''the gasket is installed''' between the sensor and the tank. After this, screw the screws from the installation kit into the previously drilled ø 3mm holes.<gallery widths="700" heights="400"> | |||

</gallery>Proceed to tank calibration. This procedure will result in a "level-liters" (or "level-gallons") table that will allow your monitoring platform to convert the level values that the sensor provides into liters/gallons that are displayed in the monitoring platform reports. You can save the table to the sensor's memory so that the sensor immediately outputs volume values in liters/gallons. You do not need to enter a calibration table on the monitoring platform. The internal memory of the TD BLE sensor can hold up to 50 lines of the calibration table. The capacity of the table on the monitoring platform is usually larger.<blockquote>In addition, it is easier to change the table or correct errors in the calibration table when it is downloaded to the platform than if the table is stored in the sensor's memory</blockquote>In order to create such a table, you need to fill the tank by step by step adding fuel to the tank batch by batch and recording level-liter(/gallon) value pairs after each batch using the tank calibration menu in the application. | |||
Suppose you need to calibrate a 100 L tank in ten 10 L portions. | |||
To do this, you should connect the sensor, press the '''"Tank calibration"''' '''(2)''' button . But before that, in the '''"Settings" (3)''' menu , make sure that the filtering level is selected '''0 (4)'''. Filtration slows down the level calculation and can increase the tank calibration time.<gallery mode="nolines" widths="300" heights="600"> | |||

</gallery>Then, you can click '''Start''' to create a new table, or click Resume to select an existing table from your smartphone memory and continue working with it. If you click Resume, you will need to locate the table file on your Android device that you created/downloaded earlier. Select another folder using the '''Main Menu button (1)''' or using the drop-down menu '''(2)'''. Select the table and click on it '''(3)'''<gallery mode="nolines" widths="300" heights="700"> | |||

Mathematical calibration '''(1)''' is [[TD-BLE#Mathematical calibration|shown in this article.]] | |||
[[File:Selecting_type_of_tank_calibration_.png]] | |||
Then, you can select the '''Fill''' or '''Drain''' method '''(1, 2)'''. The '''Fill''' method is recommended as it is more accurate. | |||
If you select the Drain method, you cannot be sure what exact amount of fuel is in the tank and whether the tank is full or not | |||
Next, give the table file a name '''(3)''' and set the serving size '''(4)'''. | |||
'''ATTENTION!''' Serving volume is not the number of servings! This is the number of liters/gallons in each serving! In the example below, the tank supposedly contains 100 liters and this volume can be divided into 10 portions of 10 liters. If the volume of the tank was 300L and it needed to be packaged into 10 servings, the serving size would be 30 L. | |||
After this, press Continue '''(5)'''.<gallery widths="400" heights="600"> | |||

== '''<big> | == '''<big>What to do if it is not possible to completely empty the tank?</big>''' == | ||
If you cannot completely empty the tank, you should somehow calculate the amount of fuel that is in the tank. After this, you can manually edit the table so that it looks like the example below. Or simply edit the table file before you upload it to the monitoring platform. | |||
Let's imagine that there are already 10 liters of fuel in the tank that cannot be removed, so when you place the sensor in the tank, it will immediately begin to show the level of 115, instead of 1.<gallery widths="400" heights="700"> | |||

</gallery> | </gallery>Next, you can add the next portion to the tank. The level value should change. If the level does not change, check the drain holes. They may be blocked by duct tape that you may have used while calibrating the sensor or by pieces of caulk. | ||
If this happens, the air trapped inside the tubes prevents the fuel from rising. | |||
== '''<big>Calibration of tanks with complex shape</big>''' == | |||
'''If the tank has various curves''' or other features, you should '''reduce the size of the portions and increase the number of portions''' as the fuel rises to the area with the bend or other shape feature. Once the difficult part has been completed, you can return to your original portion size. | |||
== | Let's imagine that you are calibrating a tank in 10-liter portions. The level rises to areas with complex shapes.<gallery mode="nolines" widths="350" heights="750"> | ||

[[File:Complex_shaped_tank_next_step.png|frameless|357x357px]] | |||
Once the fuel level is above the problem area, you can return to the original portion size of 10 liters. | |||
Once the tank is full, you should have a calibration chart that looks similar to the one shown below.<gallery widths="400" heights="500"> | |||

</gallery> | </gallery> | ||
== '''<big> | == '''<big>What to do if the tank cannot be filled completely?</big>''' == | ||
If in your case the level does not reach the maximum range value of 1023 or 4095 due to the fact that the tank cannot be filled completely, do not worry. If your table ends up like the following example, even though the range selected is 1 - 1023, this is acceptable | |||
[[ | [[File:Tank_calibration_table_in_.csv_format.png|none|thumb|'''Tank calibration table in .csv format''']] | ||
== '''<big> | == '''<big>How many portions should I add?</big>''' == | ||
The total number of portions depends on the capacity of the tank. Below is a table with guidelines. | |||

|} | |} | ||
These are general recommendations | |||
Basic rules: | |||
* The shorter the sensor (<30cm), the higher the filtration should be set | |||
* The closer the sensor is to one of the tank walls, the higher the filtration must be | |||
* The more rough the road, the higher the filtration should be | |||
Filtration reduces fuel level fluctuations that are caused by fuel splashing while driving. | |||
[[File:Filtration_effect.png|none|thumb|795x795px|'''<big>Before and after enabling filtering on the sensor</big>''']] | |||
= <big>'''Tank mounting'''</big> = | |||
The most common mounting method is self-tapping screws with a sealing washer. It is also possible to install on threaded crimp nuts, welded bushings and other structural elements. The sensor can be mounted on pre-prepared places using screws and bolts with strength class not less than 4.8. It is necessary to ensure tightness of the connection between the sensor body and the tank. For additional protection it is allowed to use automotive oil and gasoline resistant sealant. | |||
For plastic tanks rivets and bolts can be used. | |||
== <big>'''How hard to screw in self-tapping screws'''</big> == | |||
[[File:How_to_hard_to_tighten_the_screws.png|frameless|512x512px]] | |||
== <big>'''Saving a calibration table to the sensor memory'''</big> == | |||
If the calibration table is ready, you can '''save it to the sensor's memory so that the sensor will output volume values''' in liters/gallons. | |||
To activate this function, go to the '''Additional settings''' menu and press '''Conversion to liters''' .<blockquote>This function is not recommended for use if your platform supports the use of a billing table, because to edit the table on the sensor you will need to travel to the sensor, while the table on the platform can be edited remotely at any time.</blockquote>After that you can activate the conversion to liters or gallons and enter the conversion table manually or by uploading a ready table file. | |||
'''''If the table file is not selected - move it to another folder and try again, it is also desirable that the file name contains only digits''''' | |||
Activate '''Conversion to liters(1'''). | |||
To create the table manually, select Level'''(2''') or Liters'''(3''') - in this case it can be any volume unit, enter the value'''(4''') and click on the arrow'''(5'''). Then, click on the three dots icon'''(6''') and then click Save to sensor ('''7''').<gallery mode="nolines" widths="350" heights="550"> | |||
File:Recalculate_page.png|alt= | |||
File:Recalculate_page_settings.png|alt= | |||
</gallery>In order to import a table from the .csv file that you created earlier when calibrating the tank, click on the three dots icon (1), and then click Import from file (2). After that, find the desired file on your smartphone and click on it. | |||
Save the imported table to the sensor (3) | |||
[[File:Recalculate_page_settings_2.png|frameless]] | |||
= '''<big>Common issues and solutions</big>''' = | |||
== '''<big>Level does not change</big>''' == | |||
First of all, check if the '''conversion to liters has not been enabled'''. | |||
If you did this without saving the table to the sensor’s memory, the sensor will not be able to display either the level or volume in liters.<gallery widths="350" heights="600"> | |||
File:Recalculate_disabled.png|'''Recalculate in litres is disabled''' | |||
File:Recalculate_enabled.png|'''Recalculate in litres is enabled''' | |||
</gallery>Another possible reason could be that the sensor has not been properly calibrated and its CNT is below the Empty calibration value. In this case, recalibrate the sensor. | |||
Also, if you calibrated the sensor with fuel, it is possible that the sensor drain holes have remained closed and air trapped inside is preventing fuel from rising through the tubes. | |||
== '''<big>Level 7000</big>''' == | |||
Level 7000 is an error code Short circuit. This indicates that there is dirt, water, chips or other impurities in the tubes. All of these can be highly conductive, while the sensor is designed to work with dielectrics such as fuel. | |||
[[File:Level_7000.png|frameless]] | |||
You should clean the sensor tubes preferably by flushing them with the clean fuel and blowing them through the drain holes with compressed air. | |||
If this error occurred after the start of operation of the sensor, it means that most likely these impurities got into the sensor tubes from the tank and in this case it is also needed to ensure that the tank itself doesn't contain any contaminations. Clean the tank, if necessary. Note that a fuel level sensor installed outside a contaminated tank may function correctly, but the same sensor installed in such a tank may generate this error code. | |||
== '''<big>Level 6500</big>''' == | |||
This code may indicate that the tubes have lost contact. This error code may be generated immediately after cutting the tubes. In this case, simply calibrate the sensor. | |||
[[File:Level_6500.png|none|thumb|'''<big>Level 6500 and CNT below 10000</big>''']] | |||
If this does not help, check the CNT. If the CNT is below 10,000, it is very likely that the tubes are not in contact with the sensor board. | |||
Take a photo of the sensor head (the sensor serial number should be visible), its tubes (the correspondence or discrepancy of the tubes length should be clearly visible), take a screenshot of the main screen of the sensor and the Settings menu page in the application and send these data to tech support. | |||
== '''Connection losses, issues with coordinates, power supply issues''' == | |||
In case TD-Online goes offline for several days, it is necessary to check the messages the device sent before going offline or, if it has come back online, to check the messages sent from the black box. On Wialon platform such messages are marked with blue color. | |||
The dianostic parameters that need to be checked are: | |||
- '''SRN''' - in case it is higher than 30, there is an issue with the GPS connectivity; either the connection with satellites is poor in this area or there is an issue with the device's GPS module or its antenna | |||
- '''RSSI''' - Received Signal Strength Indicator - shows the quality of GSM signal reception; if the values you see are below 20 this means that either the local 2G/4G coverage is poor or there's an issue with the GSM modem or its antenna | |||
- '''msg_num''' - a cumulative counter of the messages sent; it can reset from time to time but if it happens too often then most likely there's an issue with the power supply the sensor is connected to | |||
[[File:TDOnline diagnostic parameters.png|980x980px]] | |||
=== Checking the device manually === | |||
If the TD-Online in question is offline for too long, it is necessary to check it manually. | |||
Once next to the vehicle: | |||
1) Before doing anything with the wiring, try and check if the device can be detected via Escort app (via Bluetooth) | |||
2) If it cannot be detected, there's something with: | |||
* a) the cable | |||
* b) the fuse | |||
* c) the device itself | |||
3) Try and connect the TD-Online to an alternative power supply of 12-24 V (using C200M2 RS485-USB converter is an option) and check if it can be detected via the app; if this works, run a continuity check on the cable and the fuse using a multimeter; replace either or both of them if they are damaged | |||
4) If the TD-Online is detected via the app, try and hard reset it; should it come back online on the platform, be sure to report that to the tech support team | |||
5) If the TD-Online is detected via the app but doesn't come back online on the platform no matter what you try, download the log from it and share the file with the tech support; the log file is saved in the same folder where you previously saved a tank calibraiton table; if you have never saved any tables before, be sure to create and save one (you need only a few lines in the table with whatever values)<gallery widths="250" heights="400"> | |||
