It has capacity to measure more flow rates than weir. Accurate streamflow measurement using flume is within ±2–5% while that of weir is ±2%. Generally, flumes are employed to determine discharge where weirs are not useful. …
WebFlumes (e.g., Parshall, Palmer-Bowlus, see figure 4.3): Discharge measurement flumes produce a constriction in the flow and thus cause the flow to transition to critical flow (Froude number = 1). Similar to weirs, a measurement of the depth of critical flow and relevant flume dimensions can be used to estimate the discharge through the flume. WebSo measuring flow rate (CFS) can be done by simply measuring the depth of the water upstream. The biggest difference between a weir and a flume is that a weir creates a pond upstream of the weir, while a flume requires much less upstream depth. This often prevents weirs from being used in flat canals or ditches, or canals with little head upstream.
