Hydrometry - Performance requirements and test procedures for water monitoring equipment - Devices for the determination of flow - Part 1: Open channel instrumentation; German and English version prEN 17694-1:2021

Abstract

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.
