Abstract
A carrier assembly for a catwalk assembly includes a carrier. The carrier assembly includes a skate to move a tubular member along the carrier. The carrier assembly includes a proximity sensor positioned to detect the end of the tubular member as it moves along the carrier. The carrier assembly includes a skate position sensor. The length of the tubular member may be determined by measuring the position of the skate relative to the proximity sensor when the end of the tubular member passes the proximity sensor.
