1. A floatless gauge assembly to be used in conjunction with a voltage source and voltage indicator or a current source and current indicator for measuring the level of a fluid in a conductive tank having a non-uniform horizontal cross sectional area, comprising:

  • a base; and

    an elongate electrically resistive/conductive polymeric member connected at one end thereof to said base and extending therefrom, said resistive/conductive polymeric member having one end thereof electrically connected to a first terminal, said elongate member having a resistance profile corresponding to the variations in horizontal cross sectional area of said tank.
