BS EN 17694-1:2023 Hydrometry. Minimum performance requirements and test procedures for water monitoring equipment. Devices for the determination of flow - Open channel instrumentation
1 Scope
This document specifies general requirements, minimum performance requirements and test procedures for open channel instrumentation used to determine either volumetric
flow-rate and/or total volume passed of waters in artificial open channels. It covers the following
technology categories:
— Level sensors with associated electronics designed to be used with a conventional
gauging structure. (The requirements and test procedures for gauging structures, such
as weirs and flumes, are excluded. The stage discharge characteristics for many of
these structures are established and published in national and international standards).
— Water velocity sensors.
— Integrated velocity area instruments 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 recognized that for some OCIs , certain tests cannot be carried out.
