Abstract
Insertion paddlewheel flowmeters were removed from field installations after 12 to 24 months of service for inspection and calibration. The tests were designed to identify meter degradation because of scale and debris on the paddlewheel and/or normal wear and tear. Results show that the dirty and clean meters do not have a significant performance difference. It was also found that results of meter testing in a four inch diameter test section can be extended to larger diameter pipes.
