  • Apparatus for measuring pipe length
    Patent number: 4170067
    Abstract: A pipe is cradled at rest on a weighing scale at the end of a pipe mill production line. Pipe end sensors are driven axially in opposite directions until each one makes contact with an end of the pipe. Movement of each sensor toward an end of the pipe causes a pulse generator to produce pulses that decrement from a preset value indicative of the distance between two axially disposed reference points.
