HM 162.51 Venturi Flume Show data sheet (pdf file) Print page
Technical Description

The HM 162.51 is a fully functional model of a Venturi channel measuring device. Its action is produced by a horizontally arranged constriction of the channel cross-section; this is formed using 2 Plexiglass side bodies. In this way the cross-section of the constriction is clearly visible. The flow processes of subcritical and supercritical flow can be clearly observed. Along with a flow rate measurement, an energy balance after Bernoulli can be clearly demonstrated in conjunction with the pitotstatic tube HM 162.50 and HM 162.59.


Learning Objectives / Experiments

- Flow rate measurement in open flumes using the continuity equation
- Investigation of flow and supercritical flow states

For measurement of water levels, the use of the level gauge HM 162.54 on the moving instrument carriage HM 162.59 is recommended.
