Site selection principles
1. Should avoid clock 6 or 12 point position, so as to avoid sediment at the bottom of the pipe or pipes upper part of the bubble, air-pocket caused by signal attenuation.
2. Fully considering the tube wall scaling condition, as far as possible choose no scaling section measuring, can fully meet, need to think about scaling for lining in order to get better the measurement accuracy.
