Skogerboe GV, Hyatt ML, England JD, Johnson JR (1966) Measuring water with Parshall flumes It was found that the formula predicted highly accurate discharge corresponding to the given depth of water, which was indicated by the fact that the values of CC and RMSE as yielded by the formula on the testing data set were 0.976 and 0.338, respectively. The predictive capability of this formula was analyzed with the help of common statistical indices, i.e., coefficient of correlation (CC) and root-mean-square error (RMSE). This formula was generated using multivariate regression applied with the help of the mvregress command present in Statistics and Machine Learning Toolbox™ in MATLAB. ![]() An attempt was made to generate a versatile discharge formula that can be used for both the Parshall flumes. In the present study, 1 PF and 1 MPF of throat width 2.54 cm and 3.18 cm were studied under no-slope and positive longitudinal slope conditions by observing the depth of water at a specific point in each flume at different discharge values. These are given preference over weirs because of their ability to measure higher flow rates, self-cleaning capability as well as low head loss as compared to weirs. They are widely used for the measurement of sewage flow, industrial discharge, seepage in dams, etc. With its multiple functions, available options and minimal maintenance – Flume Systems are the perfect, custom-fit product transferring solution for your potato and produce operation.Parshall flumes (PFs) and modified Parshall flumes (MPFs) are specially designed devices that are commonly used for the measurement of discharge in open channels. The closed (pipe) model is available as a siphon or pump system. It is customized to your operation through a number of available configurations, including open trough and closed models. ![]() Flumes are ideal for transferring over longer distances, in any direction or angle, based on your facility’s footprint and equipment layout. Our Flume Systems transfer product in the early stages of processing, while also separating dirt and debris and gently washing product.
