ABSTRACT:
A device for measuring the length of a string of well pipe as it is run into or pulled from a well bore and for counting the number of pipe collars connecting the pipe sections together includes a support frame having an opening therethrough for accommodating a pipe string. A laterally moveable carriage is mounted on the frame. A measuring wheel and a roller are connected to the carriage. Tension springs connect the roller to the carriage for urging the roller and measuring wheel into engagement with the well pipe and pipe collars. An actuator is connected to the roller for registering lateral movement of the roller. Recoil springs connect the carriage and the frame for absorbing the force of the shock caused by contact of the measuring wheel with the pipe collars and means are connected to the measuring wheel to convert rotational travel of the wheel to the length of the pipe string measured.
