In 2009, Vivax-Metrotech produced a revolutionary pipeline data acquisition system, MetroCart. Unlike the traditional pipeline instrument, MetroCart uses multi-dimensional remote sensing technology and RTK real-time differential GPS positioning technology. Using multi-dimensional sensors near the pipeline, it can measure the pipeline direction, plane position and buried depth without being directly above the pipeline, and it displays the pipeline path map and GPS coordinates from each measuring point on the screen in real time. All measurements are intelligentized and automated. Although its depth detecting needs to be further improved, the modern scientific and technological level embodied by the machine can not be ignored. In the near future, these technologies may be widely used in pipeline meters.
