Product Description

Parshall FlumeParshall Flume


Since its development in 1922 by Dr. Ralph L. Parshall of the U.S. Soil Conservation Service, the Parshall flume has become the most commonly used flume for monitoring industrial and municipal sewage. Initially intended for the measurement of irrigation flows, the TRACOM‘s Parshall flume is a particular type of venturi flume which constricts the throat of the flume to produce a differential head that is related to the flow rate. The tapered approach section followed by the downward sloping floor of the throat gives the Parshall flume its ability to withstand relatively high degrees of submergence without affecting the flow rate.

Features and Benefits:

  • Self-cleaning capacity
  • A wide operating range requiring only a single head measurement
  • Minimum of lead loss (about ΒΌ of that of a similarly sized weir)
