Active Speed Control Technology 

When an inspection tool moves too quickly through a line, data quality can suffer. High velocity gas lines for example, can flow so rapidly that accurate magnetic flux leakage (MFL) metal loss inspections become impossible. The solution is active speed control, which is specifically designed to pair with MFL inspection technology for use in high velocity gas lines. In fact, TDW large-diameter GMFL tools were designed to facilitate the addition of a speed control unit. XYZ Mapping and Deformation (DEF) capabilities may also be added to provide multiple data sets from multiple technologies in the same inspection run.
