HM 160.40 Radial Gate Show data sheet (pdf file)
Technical Description
The radially adjustable weir or radial gate is one of the forms of adjustable weirs, the water flows under the weir gate. The weir is fitted to the side walls of the channel. It comprises a strong base plate; the gate can be moved around a fixed bearing point on the base plate. The gate is of circular cross-section and, along with the guide rods, also has a further rod using which the gate is activated, it can also be locked in various positions. Radial gates have the advantage that the friction forces generated when the gate is moved are low. Radial gates are used, e.g. if the flow forces are so large that the usage of an undershoot weir is prohibited by the large amount of friction caused when moved.
Learning Objectives / Experiments
In conjunction with the HM 160, the following experiments are possible:
Observation of flow forms
Observation of discharges under a radial gate:
- Observation of hydraulic motion on discharge
- Observations on the movement of upper rollers
Hydrostatic pressure on a weir

For the exact measurement of water levels, the HM 160.52 Level Gauge is recommended.
