TRAINING OBJECTIVES
Study and use of thin weir plates for flow measurement:
• Rectangular weir plate without contraction
• Rectangular weir plate with lateral contraction
• Triangular weir plate
TECHNICAL DATA
– Rectangular weir plate without contraction.
– Rectangular weir plate with lateral contraction: length 50mm x 100mm height.
– Triangular weir plate: 90°, 100mm height.
– Height measuring system with 0.1 mm precision.
– Maximum water flow: 100 liters/min.
– Inclined manometer with a bubble level for water level reading.
– Baffle for sloshing reduction.
Necessary accessory:
DL DKL-014 – Hydraulic bench
The basic hydraulic bench is a simple, mobile, self contained module that allows a supply of “hydraulic energy”, i.e. an accurately controlled and measurable flow of water.
It includes two collecting tanks, a centrifugal pump, a flowmeter, a mobile frame work on wheels, a set of valves and piping.
FLOW OVER A WEIR
It consists of some weir plates of different shapes that can be coupled to the surface channel of the DL DKL014 – Hydraulics Bench (not included).
The height of the upstream weir plate is measured by an inclined manometer connected by a tube to the channel bottom.
