Pipelines are the most common water transportation and irrigation facilities. During transportation, pipelines effectively reduce evaporation and leakage of water resources. Magnetic flowmeters measure accurately discharge flow. It is a crucial action of rational water resource allocation and reasonable water fee collection.
