Dam of the hydroelectric power plant
Flow measurement at the dam
Process data
Measuring task:
Flow
Measuring point:
Channel
Measuring range up to:
0.5 m
Medium:
Seepage water
Process temperature:
+5 … +10 °C
Process pressure:
0 … 0 bar
Special challenges:
Very humid atmosphere, condensation
Application
The seepage water in the dam of the hydroelectric plant is collected in pipes or channels. The quantity of seepage water provides information on the condition of the dam (another indicator of the condition of the dam is the clouding of the seepage water which is also assessed). The quantity of water flowing in an open channel is measured via water head height as it passes through a ‘V’ notch, flume or weir structure, which is then calculated into flow rate.
