ИСРСМ ТК 18 - Акредитација, оцена на сообразност и метрологија
adopted two new standards in the area of Hydrometry
The standard defines general requirements, minimum performance requirements and test procedures for open channel instruments used to determine either volumetric flow rate and/or total volume of water in artificial open channels.
It covers the following technological categories:
- Level sensors with associated electronics designed to be used with a conventional measuring structure.
- Water speed sensors.
- Integrated instruments for the speed area consisting of level and speed sensors that can be separated or combined in one assembly.
- Speed sensors that determine the average speed of water through a channel.
This standard defines general requirements, minimum performance requirements and test procedures for instruments used to measure either volumetric flow rate and/or total volume of water passing through closed channels.
It covers all closed pipe (CCI) technologies intended for operation in closed pressure pipes and partially filled pipes.
