Hydrometry. Guidelines for the application of acoustic velocity meters using the Doppler and echo correlation methods Ingestion-build-48348 The ICNIRP Guidelines [1] provide1 Scope This International Standard provides guidelines on the principles of operation and the selection and use of Doppler based and echo correlation velocity meters for continuous flow gauging. This International Standard is applicable to channel flow determination in open channels and partially filled pipes using one or more meters located at fixed points in the cross section. NOTE A limitation of the techniques is that measurement is made of the
