- Abstract:
- To overcome the disadvantage of building weirs and flumes, recently velocity-area meters have been developed, using that electromagnetic or ultra-sound Doppler effect principle. In these meters the wet area is evaluated using liquid column pressure or ultra-sound.
The importance of flow rate measurement of open channels is growing as a result of environmental impacts caused by the wastewater produced in metropolitan areas. This brings up the need of wastewater collection and treatment, where flow rate is a very important parameter.
This paper describes a prototype of a facility for the calibration of these new types of meters. This paper also describes the results of calibrations of one Ultra-Sonic Doppler meter and one electromagnetic meter. - Keywords:
