出版：British Standards Institution
专家解读视频
Describes the operation and the establishment of an ultrasonic (acoustic) gauging station for measuring discharge in an open channel, a river, or a closed conduit with a free water surface. Also deals with the basic principles on which the method is based, and the performance and operation of associated instrumentation. Apart from definitions, Coverage includes methods of measurement ( for example, computational requirements and system calibration) and gauging station ( for example, system output and maintenance). Also includes tables.
