Hydrometry — catching-type liquid precipitation measuring gauges
|Publication Date:||19 June 2020|
|ICS Code (Flow in open channels):||17.120.20|
This International Standard specifies the typical requirements of instrumentation for measuring liquid precipitation, primarily for the purpose of hydrological and meteorological observation. Its scope is limited to both non-recording and recording catching-type precipitation gauges for the measurement of liquid precipitation. The standard covers design criteria for the gauges and elements of uncertainty that need to be considered in their construction.
This International Standard is supplemented by an annex providing guidance on the types of catchingtype liquid precipitation measuring gauges currently available and the measurement uncertainty associated with them
