Abstract
Systems for pipe tallying in well drilling operations and methods for using the same are described. The pipe tallying systems determine a number of pipe joints that pass through an inlet based on the diameter of the pipe joint when compared against a drill pipe diameter. The pipe tally system maintains a tally of drill pipes in a borehole and the pipe tally system can produce a borehole depth measurement based on the length of pipe in the borehole.
