Abstract
An apparatus for determining the height of liquid in a storage tank comprising: an instrument shaft capable of being associated with the shaft of the tank level gage; a first disc rotatable in response to the rotation of the instrument shaft; a second disc rotatable in response to the rotation of the first disc; first and second signal emitters associated with the first and second discs, respectively; and first and second signal receivers associated with the first and second signal emitters, respectively. A different, distinct pattern of signals is received by each of the receivers for each radial increment of disc as each disc rotates. The patterns of signals received by the first and second receivers are translatable into the height of liquid in the tank.
