Wide Scan Technique for Large Diameters

VTube is immune to diameter sizes if you follow techniques to handle larger diameters. If a diameter surface stripe does not cover enough angular distance, then the math engine loses accuracy in calculating the centerline of a straight.

For diameters 6" and greater, you can switch to the wide-scan technique. On larger diameters, it is important to scan in points from a wider area of the tube.

  • First scan one end.
  • Second - move to the other end, and rotate the probe around the tube slightly. We recommend about 90 degrees of rotation. Then scan the new end and new side of the cylinder.

This will give the math engine much better data to fit the centerline to
