GB/T 11828.1-2002

📋 Scope / 适用范围 ai_extracted

GB/T This part of 11828 specifies the product classification, technical requirements, test methods, inspection rules, as well as requirements for packaging, marking, transportation, storage, and warranty period of float-type water level gauges. This part is applicable to float-type water level gauges (hereinafter referred to as "water level gauges") used in natural water bodies such as rivers, lakes, open channels, and reservoirs.

📝 Foreword / 前言 ai_extracted

GB/T 11828 "Water Level Measurement Instruments" is divided into seven parts: - Part 1: Float-type water level gauge; - Part 2: Pressure-type water level gauge; - Part 3: Groundwater level gauge; - Part 4: Ultrasonic water level gauge; - Part 5: Electronic encoding water gauge; - Part 6: Telemetry water level gauge; - Part 7: Water level needle. This part is Part 1 of GB/T 11828, replacing the content related to float-type telemetry water level gauges in GB/T 11828-1989 "Measurement of liquid flow in open channels - Float-type water level gauges" and GB/T 11830-1989 "Hydrological measurement and reporting devices - Telemetry water level gauges". Compared with GB/T 11828-1989 and GB/T 11830-1989, the main changes in this part are as follows: - Added definitions for "float-type water level gauge" and "water level encoder"; - Reclassified product categories; - Reclassified display modes and recording modes; - Detailed the reliability requirements and their test sections to enhance operability. This part is coordinated with standards such as GB/T 15966-1995 "Basic parameters and general technical conditions for hydrological instruments" and SL/T 224-1999 "General technical conditions for water level gauges". This part is proposed by the Ministry of Water Resources of the People's Republic of China. This part is under the jurisdiction of the Hydrological Instruments Subcommittee of the National Hydrological Standardization Technical Committee. This part is drafted by: Nanjing Research Institute of Hydrology and Water Conservation Automation. Main drafters of this part: He Shengrong, Zhang Yucheng, Yao Yongxi, Xia Kang. The previous versions of the standard replaced by this part are as follows: - GB/T 11828-1989, GB/T 11830-1989.

📖 Terms & Definitions / 术语和定义 ai_extracted

浮子式水位计

float-type stage gauge 利用水面浮子及其相应装置感应水位变化，将水位参数进行记录或显示的水位观测仪器。它一般包 括浮子式水位传感器和显示记录器，还可包括水位编码器和电源。其传感器可具有电量信号输出接口， 能将水位参数传至远离观测现场处进行记录或显示。显示记录器应带有计时功能。

Float-type stage gauge A water level observation instrument that utilizes a float and its corresponding mechanism to sense changes in water level, recording or displaying water level parameters. It generally includes a float-type water level sensor and a display recorder, and may also include a water level encoder and a power supply. The sensor may be equipped with an electrical signal output interface, enabling the transmission of water level parameters to a location remote from the observation site for recording or display. The display recorder shall be equipped with a timing function.

水位编码器

water level encoder 水位编码器是浮子式水位传感器的转换器件，它完成水位参数的信源编码，并将水位量或水位变化 量转换为电信号输出。

Water Level Encoder The water level encoder is a conversion device for float-type water level sensors. It performs source encoding of water level parameters and converts the water level value or water level variation into an electrical signal for output.
