No - Parshall flumes are similar in shape but are NOT scale models of each other.  As a result, it is not possible to interpolate non-standard sizes and know the flow equation with certainty.  As a short-throated flume, each size of Parshall flume must be calibrated.

For the exact dimenions of various Parshall flume sizes, please vist our Parshall Flume>Dimensions page.
