GB/T 13336-2019The series model of hydrometrical instruments (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 13336-2007 "Hydrological instrument series spectrum", compared with GB/T 13336-2007, except editorial modification In addition, the main technical content changes are as follows:

--- Removed the terms and definitions of "airfoil lead fish" and "elliptical line type lead fish" (see 3.1,

3.2 of.2007 edition);

--- In the "rain gauge" classification in the "precipitation measuring instrument", the "float type" was deleted, and the "volume type" was added;

--- Added three levels of classification and related content of "water sampling and monitoring instruments";

---In the "Automatic Monitoring System Equipment" category, the "soil moisture (sentiment) automatic monitoring system equipment" was deleted, and the "pump gate station" was added. Automatic monitoring system equipment";

--- Added "cable control device" to the classification of "hydrological test equipment";

--- Removed "Other" (see Chapter 4 of the.2007 edition);

--- Added "hydrological mobile monitoring equipment". This standard is proposed and managed by the Ministry of Water Resources of the People's Republic of China. This standard was drafted.

1 Scope

GB/T 13336-2019 is the Chinese national standard on the series model of hydrometrical instruments, in the field of natural and applied sciences. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 4 June 2019 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 January 2020. Classification: ICS 07.060, CCS N93. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the basic classification, structural type, main parameter series division and other spectral characteristics of hydrological instrument products. This standard applies to scientific research related to various types of hydrological instrument products used in water conservancy, hydrology, meteorology, marine, environmental protection, agriculture and forestry industries. Design, manufacturing, test and test, etc., also apply to guide the preparation of standard planning and product technical conditions for hydrological instrument products.
