Cutthroat Flumes

This flume is similar to the Parshall Flume except that the parallel throat section is removed and the bottom is at the same elevation as the channel invert through the length of the flume. Being a 'zero' throat flume the range of accuracy or useable depth for the Cutthroat Flumes is directly related to length of the flume. The Cutthroat Flume is commonly used for flow splitting, but is not recommended for flow measurement.
