Abstract
An assembly of an aircraft tank and a sensor for determining a liquid level in an aircraft tank. The sensor is made up of a closure device, mounted in a port of the tank, and a measuring device, removably mounted on the closure device. The closure device has a liquid line configured to conduct liquid from the port of the tank and a member for automatically sealing the liquid line when the measuring device is not mounted on the closure device and for unsealing the liquid line when the measuring device is mounted on the closure device. The measuring device has at least one pressure measuring member configured to measure a pressure difference between a liquid pressure in the liquid line and a reference pressure, which can be a gas pressure or the atmospheric pressure, so as to infer therefrom the liquid level in the tank.
