Hydrometry - Measurement of the rainfall intensity (liquid precipitation): requirements, calibration methods and field measurements

Hydrometry - Measurement of the rainfall intensity (liquid precipitation): requirements, calibration methods and field measurements

This Technical Report describes a method for calibrating rainfall intensity (RI) gauges and the measurement requirements to obtain accurate and compatible data sets from hydro-meteorological networks, as a forerunner to the development of full hydro-meteorological data collection standards.
This Technical Report deals exclusively with catching-type RI gauges (see Clause 3). It concentrates on the generic calibration, performance checking and estimation of uncertainties for RI gauges. It does not cover specific gauge measurement principles, technical characteristics and technology adopted in the design of RI gauges.

Hidrometrija - Merjenje intenzivnosti padavin (tekoče padavine): zahteve, kalibracijske metode in terenske meritve

V tem tehničnem poročilu so opisane kalibracijska metoda za kontrolnike intenzivnosti padavin (RI) in merilne zahteve za pridobivanje točnih in združljivih nizov podatkov iz hidrometeoroloških mrež, kot predhodnik razvoja standardov za popolno zbirko hidrometeoroloških podatkov. To tehnično poročilo obravnava izključno kontrolnike intenzivnosti padavin s posodo za zbiranje padavin (glej točko 3). Osredotočeno je na splošno kalibracijo, preverjanje delovanja in oceno negotovosti za kontrolnike intenzivnosti padavin. Ne vključuje načel merjenja za specifične kontrolnike, tehničnih lastnosti in tehnologije, ki so del načrtovanja kontrolnikov intenzivnosti padavin.

Calibration and accuracy of non-catching precipitation measurement instruments
SIST-TP CEN/TR 17993:2023

Non-catching type gauges are the emerging class of in situ precipitation measurement instruments. For these instruments, rigorous testing and calibration are more challenging than for traditional gauges. Hydrometeors’ characteristics like particle size, shape, fall velocity and density need to be reproduced in a controlled environment to provide the reference precipitation, instead of the equivalent water flow used for catching-type gauges. They are generally calibrated by the manufacturers using internal procedures developed for the specific technology employed. No agreed methodology exists, and the adopted procedures are rarely traceable to internationally recognized standards. This document describes calibration and accuracy issues of non-catching instruments used for liquid/solid atmospheric precipitation measurement. An overview of the existing models of non-catching type instruments is included, together with an overview and a description of their working principles and the adopted calibration procedures. The literature and technical manuals disclosed by manufacturers are summarized and discussed, while current limitations and metrological requirements are identified.

Hydrometry - Minimum performance requirements and test procedures for water monitoring equipment - Devices for the determination of flow - Part 1: Open channel instrumentation
SIST EN 17694-1:2023

This document specifies general requirements, minimum performance requirements and test procedures for open channel instrumentation used to determine either volumetric flow-rate and/or total volume passed of waters in artificial open channels. It covers the following technology categories:
- Level sensors with associated electronics designed to be used with a conventional gauging structure. (The requirements and test procedures for gauging structures, such as weirs and flumes, are excluded. The stage discharge characteristics for many of these structures are established and published in national and international standards).
- Water velocity sensors.
- Integrated velocity area instruments comprising level and velocity sensors that may be separate or combined in a single assembly.
- Velocity sensors that determine the mean water velocity through a channel.
It is recognized that for some OCIs, certain tests cannot be carried out.

Hydrometry - Minimum performance requirements and test procedures for water monitoring equipment - Devices for the determination of flow - Part 2: Closed conduit instrumentation
SIST EN 17694-2:2023

This document specifies general requirements, minimum performance requirements and test procedures for instrumentation used to measure either volumetric flow-rate and/or total volume passed of water in closed conduits. It covers all closed conduit instrument (CCI) technologies intended to operate in closed pressurized pipes and partially filled pipes. Requirements are expressed in volumetric units which may be converted to mass using the density of the water.
It is recognized that for some CCIs certain tests cannot be carried out.
The data obtained from the testing of CCIs in accordance with the requirements of the Measuring Instruments Directive [1] or EN ISO 4064-1 [2] can be used to meet, in part, the requirements specified in this document. However, for the avoidance of doubt, compliance with the requirements of this document does not equate to compliance with the requirements of the Measuring Instruments Directive or EN ISO 4064-1.

Optimal design of hydrometric networks
SIST-TP CEN/TR 17798:2022

This Technical Report (TR) provides guidance to assist with the planning and design of Hydrometric networks, to ensure a better understanding of the water cycle, and that any data are observed and collated in an effective and appropriate manner. The TR is intended for use when:-
• a new network is being planned and designed;
• the nature, value and extent of an existing network is being reviewed;
• a redundant network is being decommissioned or modified.
This is to ensure that the impacts of these changes are considered objectively, and all changes are adequately monitored and recorded.
This TR covers all aspects that are considered pertinent to the evaluation. The information will be used to inform the decision-making process employed by the network’s owners and operators. The objective nature of the review will ensure that all influential factors, both beneficial and otherwise, are considered. This will ensure that primary and potential alternative uses of the network are considered. It will also ensure compliance with any extant environmental legislation.

Hydrometry - Measurement requirements and classification of rainfall intensity measuring instruments
SIST EN 17277:2019

This document considers liquid atmospheric precipitation and defines the procedures and equipment to perform laboratory and field tests, in steady-state conditions, for the calibration, check and metrological confirmation of liquid precipitation measurement instruments. It provides a classification of catching-type measurement instruments based on their laboratory performance. The classification does not relate to the physical principle used for the measurement, nor does it refer to the technical characteristics of the instrument assembly, but is solely based on the instrument calibration. Attribution of a given class to an instrument is not intended as a high/low ranking of its quality but rather as a quantitative standardized method to declare the achievable measurement accuracy in order to provide guidance on the suitability for a particular purpose, while meeting the user’s requirements.

Management of observed hydrometric data - Guidance
SIST-TS CEN/TS 17171:2018

This document gives recommendations for the management of observed hydrometric data, including raw data and other data as well as statistics derived from these observations. Although the principles of data management can be applied to all hydrometric observations, particular focus is placed on measurements of precipitation, water level (including stage), volume and discharge in open channels.
NOTE   The range of sites where water levels, and sometimes flow, are measured includes lakes, reservoirs, rivers, canals, tidal waters, sewers, wells, and boreholes.
The document covers metadata associated with hydrometric data, including recommendations for the production and management of descriptive, analytical and statistical material relating to sites where and measuring techniques, by which hydrometric data are collected. The recommendations of this document can be applied to some forms of data directly derived from observational records (for example, summary time series of monthly mean river flows). While not primarily designed for the management of data resulting from more complex numerical models or spatially aggregated data sets (for example, remotely-sensed data), many of the recommendations are applicable for such types of data.
This document does not cover the field collection of data or its transmission, but focuses on the management of data once they have been received in a hydrometric information management system.
