摘要：
An electronic device helped Shell Deer Park Refining Co., Deer Park, TX, achieve trouble-free measuring of two difficult pipe spools during a distillation unit turnaround. The tool, called the total station device (TSD), allows three-dimensional measurements with an accuracy of ±1/16 in. for lengths greater than 100 ft. The device replaces the surveyor's theodolite, which only measures horizontal and vertical angles. In addition to angles, the TSD measures distances. Beyond the usual land surveys, the TSD can take measurements for the fabrication of new piping spools and handle an array of other measurement challenges.
