Abstract
A method of calibrating a level sensor installed in an empty tank. In the tank, the level sensor includes a float that is allowed to rest against a first stop, such as the tank bottom or tank top. This position of the float is stored as a first level, such as a minimum level, in memory of sensor electronics of the level sensor. The float is thereafter moved, such as under the force of gravity by inverting the tank, against a second stop such as the tank top or the tank bottom. This position of the float is stored as a second level, such as a maximum level.
