I was curious how accurate those are, found a datasheet for the PRO-OBL-201A ($1600, or effectively nothing compared to an oil pipeline). It's a portable "optical break detector", full blown reflectometers might have more features.
They list the maximum range as 100 Km, with accuracy of +/- (0.8 m + 0.001% x Distance). So measuring to a break at maximum range, you'll be within 1.8 meters.
