			== '''<big>How to change the voltage range in the analog output</big>''' ==
			If you need to connect the sensor to a tracker using analog output and adjust the voltage range (minimum and maximum values) for compatibility, you can do so in the "'''Settings'''" menu. There, you can enter the minimum and maximum voltage values ('''1''') within the range of 0.2 V to 20 V, and then press the "'''Install'''" button ('''2''') to apply the changes.

			For example, if your microcontroller's analog input can only accept a voltage range of 3 V to 7 V, you can adjust the minimum and maximum thresholds of the TD-150-BLE’s analog output accordingly to ensure compatibility between the devices.

Installing a single sensor in an elongated tank will allow you to detect drains and refills.

			== '''<big><u>Installation locations in tanks of complex shapes</u></big>''' ==

			=== '''<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.

			[[File:Saddle shape side view.png\|frameless\|749x749px]]

			=== '''<big>Cylindrical tank</big>''' ===
			In this case, the sensor must be installed in the geometric center of the tank.

			[[File:Cylindrical tank inside view.png\|frameless\|750x750px]]

			==== '''<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.

			[[File:Cylindrical tank long inside view.png\|frameless\|750x750px]]

			==== '''<big>Ladder shape tank</big>''' ====
			If there is a difference in height in the tank and there is no common bed, it may be necessary to install two fuel level sensors.

			[[File:Ladder 2 tank.png\|frameless\|782x782px]]

			[[File:Ladder 2 tank inside view.png\|frameless\|750x750px]]

			===== '''<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.]
