30 flow measurement 5 1 2 measurement procedures using weirs to obtain a true measurement of the flow over weirs certain dimensions must be respected because they are critical to correct operation.
Calorimetric flowmeter the calorimetric principle for fluid flow measurement is based on two temperature sensors in close contact with the fluid but thermal insulated from each other.
Flow rises in the vertical tapered tube and takes a certain equilibrium position for any given flow rate.
Fluid flows up through the tapered tube and suspends a float in the column of fluid.
The objective of our presentation is comparisons of different flow measuring devices 2.
The rotameter reads the flow rate directly.
Obviously the tube must be vertical and the device does not give accurate readings for fluids.
The selection of a specific weir or flume often depends on the hydraulic conditions of the canal and the specific objectives of flow measurement.
