Department of the Interior, Bureau of Reclamation. Parshall flumes are sized by throat width, and conform to standardized dimensions published by the U.S. The Parshall Flume has been the most widely used flume for fixed flow monitoring installations. Please call us at (435) 755-0774 to learn more, we are remote data and automation experts. We provide a variety of sensors, dataloggers, and data retrieval systems (including via internet) for monitoring flow rate remotely.
Contact us to receive a quote for any of these types of products. We have relationships with companies that manufacture fiberglass and steel flumes, weirs, manholes and shelters. Contact us for a no-obligation consultation.
We offer other types of flumes, such as the H-flume or trapezoidal flume, these are generally used in specific applications and may be a good choice for your needs. All of these flumes come in a wide range of sizes, and provide good accuracy. There are many different types of flumes, we recommend either the ramp flume or cutthroat flume for most irrigation flow sites, but the parshall flume is also a good choice. A flume operates in “free flow” condition, meaning that it does not completely stop the flow of water by damming the channel. A flume is similar to a weir, but they do not create so large a change in upstream head. All flumes work by measuring how much the water rises in level before an obstruction (the flume) of known dimensions and shape. Flumes are an accurate and effective way to measure flow rate in open channel flow applications.
