An advantage of the Parshall flume is that the overflow depth (water level) is measured in a converging section, where the velocity increases and the streamlines are more stable. Any sedimenting substances settle to the bottom of the channel before reaching the Parshall flume; therefore, this measurement method is generally not sensitive to sedimentation, and at higher flow rates, undissolved substances are washed past the Parshall flume.
FIEDLER AMS s.r.o. handles the delivery and transport of the Parshall flume from the manufacturer to the installation site and, following its installation, also equips the flume with appropriate measuring equipment.
