A » A Parshall flume measures flow rate by directing water through a narrowed throat, creating a change in water level, or head, that correlates to flow rate. The head difference between upstream and downstream sections is used in a calibrated equation to calculate the flow rate, allowing for accurate and reliable water measurement in open channels, crucial for water purification and resource management.
