ABSTRACT:
A portable laser system includes a laser unit and a target unit for measuring the length of a series of pipe assemblies. Either the laser unit or the target unit engages a threaded coupling at one end of the pipe assembly and the other unit engages external pipe threads at an opposite end of the pipe assembly. The laser unit includes a resident memory (i.e., the memory moves with the laser unit), so that the laser system can read the length of more than one pipe assembly before downloading the readings to a computer. The computer then compiles the readings in groups of twenty and calculates an anticipated overall length if the pipe assemblies were interconnected as a string of pipes.
