Popis:	Good water measurement systems enable accurate accounting of water use and permit the available water to be supplied at optimum rates to the areas where it is intended to be used. A Parshall Flume is normally used as flow measuring device for open-channel flow. It is suitable to ease of manufacture and installation. At the point of measurement there is much work has attempted to calibrate and develop a discharge relation equation for large Parshall Flume. Hence, accurate relation between discharge and upstream head valid for small sizes of Parshall flume is required. In present paper four different sizes of Parshall flumes, having different throat width fabricated and tested in the laboratory under free-flow condition. Coefficient of discharge and exponent are determined by using MATLAB programming and developed a single equation for the different flume sizes. The relation is simple and suitable to use for the small Parshall Flume.
