Scope
Main technical content: This standard specifies the technical requirements, test and inspection, marking, packaging, transportation, and storage of radar flowmeters (referred to as "radar flowmeters"). This standard applies to the production and manufacture of radar flowmeters that use the Doppler frequency shift principle to measure the flow velocity of fixed points on the water surface, and does not apply to high-frequency radar and ground wave radar instruments such as those in the VHF or UHF bands.
