Flow Measurement Devices Ppt

The selection of a specific weir or flume often depends on the hydraulic conditions of the canal and the specific objectives of flow measurement. One of the two sensors is constantly heated and the cooling effect of the flowing fluid is used to monitor the flowrate. Not all flow measuring devices are suitable for all conditions.

Flow rises in the vertical tapered tube and takes a certain equilibrium position for any given flow rate. Obviously the tube must be vertical and the device does not give accurate readings for fluids. These are indicated in figure 31 and are the level of the weir crest rela tive to the channel bottom the horizontal distance between the.
