Abstract
An apparatus and method for measuring a level of a liquid is provided. Generally, the apparatus contains a first coaxial cable section including a first center conductor, a first outer conductor and a solid dielectric between the first center conductor and first outer conductor. The apparatus also contains a second coaxial cable section including a second center conductor, a second outer conductor and an air dielectric between the second center conductor and second outer conductor. Further, a coupling is provided between the first and second coaxial cable sections, wherein the second coaxial cable section is disposed in a liquid for determining a level of the liquid.
