The Set of Plate Weirs experimental set-up includes 4 different weir plates that can each be placed on a weir carrier and then fitted to the base of the channel. Tubular seals made of plastic inserted in slots on the side of the weir plates complete the experimental set-up. They are used for measuring the flow rate, whilst sharp edged aerated overflow can be investigated on the plate weir. The weir plates and weir carrier are made of PVC. The weir plates represent an aerated plate weir, a Thomson weir, a rectangular thin plate weir, and a Cipoletti weir. Apart from the aerated plate weir, all of the weirs mentioned are measuring weirs.
