* 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. | * 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.

<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. | <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. | ||

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. | 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. | ||

'''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. | '''Note.'''

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. | Use a hacksaw to cut the tubes.
