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.

			=== '''<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.

			==== '''<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.]
