Calculations for the dual scale system .

Refer to LeverArmLength to determine a lever arm length and the maximum angle to use for a given elevation difference

The size of the float can be determined using a moment balance around the pivot of the lever arm. This is to ensure that a change in head in the entrance tank will cause a similar change in the relative height of the float. The float was sized using the same float sizing algorithm used by the linear CDC.
