Methods for installation of sensors and determining a fuel level measurement of fuel using a fuel level measurement system

Abstract:

An example method for installing optical sensors for a fuel level measurement system includes mounting a plurality of fittings through a wall of a fuel tank, positioning a plurality of optical sensors within the plurality of fittings and a respective optical sensor includes a first pressure sensing end inserted through the fitting and internally into the fuel tank and a second end extending externally from the fuel tank, and mounting an optical fiber bundle external to the fuel tank. The optical fiber bundle has an optical fiber connected to each of the plurality of optical sensors for guiding light to each of the plurality of optical sensors.
