HM 162.33 Crump Weir with Piezometer Tube Show data sheet (pdf file)
Technical Description
The crump weir is a fixed underwater weir and is fitted to the base of the channel using the HM 162.54 Base Plate. The weir body has pressure measuring holes that, via transparent vertical pipes, facilitate the measurement of the static pressure in the weir over which the water is flowing and at the weir crest. Tubular seals made of plastic inserted in slots on the side of the weir body complete the experimental set-up. In practice, crump weirs are used as so-called low overfalls.
Learning Objectives / Experiments
Flow over an underwater weir
Pressure measurements using the pressure measuring device





For exact measurement of water levels, the use of the HM 162.52 Level Gauge on the moving HM 162.59 Instrument Carriage is recommended.
