What is ISO 18320 about? ISO 18320 specifies methods of determining the stage–discharge relationship for gauging stations. ISO 18320 also specifies an accuracy for defining the stage–discharge relationship based on a sufficient number of discharge measurements, complete with corresponding stage measurements. ISO 18320 considers stable and unstable channels and includes brief descriptions of the effects on the stage–discharge relationship of the transition from in bank to overbank flows, shifting controls, variable backwater and hysteresis. Who is ISO 18320 f or? ISO 18320 on measuring liquid flow in open channels is relevant to: Manufacturers of open channel flow measurement devices Installers of ultrasonic level sensors Authorities of flow measurement Hydrologists Why should you use ISO 18320? The relationship at a gauging station between stage and discharge is commonly referred to as the stage–discharge relationship, rating curve or rating. ISO 18320 is about stage–discharge relationship which has been develope...
