1. A sensor for measuring a temperature profile of a fluid within a vessel, the sensor comprising:
an array of elements, each element having a temperature-dependent parameter, the array being capable of deployment within or adjacent the vessel such that the array extends along the vessel for measuring the temperature profile, the temperature profile being indicative of a quantity of useful fluid in the vessel,
the elements of the array being coupled together in parallel or in series, the array comprising a cuttable substrate that can be cut to length to determine a number of elements within the array.
