| Resumen: | This European standard specifies general requirements, minimum performance requirements and test procedures for open channelinstrumentation used to determine either volumetric flow-rate and/or total volume passed of waters in artificial open channels. Itcovers the following technology categories:?Level sensors with associated electronics designed to be used with a conventional gauging structure (e. g. weir or flumefor which the stage discharge characteristics are established and published in a national or international standard) or afluid velocity sensor.?Integrated velocity area devices comprising level and velocity sensors that may be separate or combined in a single assembly;?Velocity sensors that determine the mean water velocity through a channel.It is recognised that for some OCIs certain tests cannot be carried out. |
