The Parshall flume is intended for use in open channels such as irrigation ditches. Use extreme care when adapting Parshall flumes for use with round pipes. The flume's crest is usually set at an elevation higher that the floor of the upstream channel. A variety of factors influence the selection of the crest elevation. When designing a metering station it is best to follow the recommendations of a knowledgeable professional in the field.
