BS EN ISO 6416:2017 describes the establishment and operation of an ultrasonic (transit-time) gauging station for the continuous measurement of discharge in a river, an open channel or a closed conduit. It also describes the basic principles on which the method is based, the operation and performance of associated instrumentation and procedures for commissioning.It is limited to the "transit time of ultrasonic pulses" technique, and is not applicable to systems that make use of the "Doppler shift" or "correlation" or "level-to-flow" techniques.This document is not applicable to measurement in rivers with ice.Cross References:ISO 772:2011 Ed 5ISO 4373:2008ISO/TS 25377:2007 Ed 1ISO 5168:2005(R09) Ed 2ISO 1100-2:2010 Ed 3ISO 15769:2010 Ed 1IEC 60079-0:2011IEC 61000-6-2:2005ISO 748:2007 Ed 4ISO/IEC GUIDE 98-3:2008 Ed 1IEC 60041:1991All current amendments available at time of purchase are included with the purchase of this document.
