'''''Navigation terminal''''' - the main element of the system for monitoring the operation of transportation carried out by means of satellite communication. Without it, it is impossible to control transportation, to determine the coordinates of the vehicle location. It collects information from sensors and on-board system of the vehicle, and then transmits it to the device/server, which belong to the controlling specialist. | '''''Navigation terminal''''' - the main element of the system for monitoring the operation of transportation carried out by means of satellite communication.

'''Why Should the Sensor Be Installed at the Geometric Center of a Mobile Tank?''' | |||
The highest point of the tank should be selected to ensure the sensor can measure the entire liquid level within the tank without any blind spots. | |||
The liquid level readings from a sensor installed at the center of the tank will be least affected by movement and sloshing of the liquid inside the tank. | |||
If it is not possible to install the sensor at the center of the tank, consider the option of installing two sensors diagonally at opposite corners. When liquid shifts towards one side of the tank, the corresponding sensor will show an increase in level, while the opposite sensor will show a decrease. This way, the average liquid level will remain unchanged. | |||

<blockquote>'''Attention:''' Before starting the calibration, the vehicle/tank must be positioned level with respect to the horizon, i.e., on a flat surface without any incline.</blockquote>If the tank has an irregular shape, the sensor should be installed at the point of maximum depth, as close to the geometric center as possible. | |||

When installation at the center is not possible – use two or more sensors. | |||
To increase accuracy and reduce level fluctuations, two sensors are installed in one tank. This solution is primarily used for tanks with a capacity of more than 600 liters and a length of at least 1500 mm. Sensors should not be installed directly against the tank walls. | |||
[[ | Additionally, two or more sensors should be installed if it is not possible to position a sensor at the center of the tank and/or if the tank has an elongated shape, meaning the length of the tank is significantly greater than its height. | ||

'''Note:''' Installing a single sensor in an elongated tank will allow for detecting draining and filling. However, increased level fluctuations during movement may prevent the monitoring platform from accurately calculating the liquid consumption. Therefore, installing two sensors is preferred. | |||

=== '''<big>Saddle-Style Fuel Tanks</big>''' === | |||
In this case, it is desirable to install two fuel level sensors in the deepest places along the geometric center of the depressions | |||

==== '''<big>Long cylindrical tank</big>''' ==== | |||
In the case of elongated cylindrical tanks, to improve readings while driving, it is necessary to install two sensors at an equal distance from the geometric center of the tank. | |||
