BS EN 17694-2:2023 Hydrometry. Minimum performance requirements and test procedures for water monitoring equipment. Devices for the determination of flow - Closed conduit instrumentation
1 Scope
This document specifies general requirements, minimum performance requirements and test procedures for instrumentation used to measure either volumetric flow-rate and/or total volume passed of water in closed conduits . It covers all closed conduit instrument ( CCI ) technologies intended to operate in closed pressurized pipes and partially filled
pipes. Requirements are expressed in volumetric units which may be converted to mass
using the density of the water.
It is recognized that for some CCIs certain tests cannot be carried out.
The data obtained from the testing of CCIs in accordance with the requirements of the Measuring Instruments Directive [1] or EN ISO 4064‑1 [2] can be used to meet, in part, the requirements specified in this document. However,
for the avoidance of doubt, compliance with the requirements of this document does
not equate to compliance with the requirements of the Measuring Instruments Directive
or EN ISO 4064‑1.
