Title: Standardization and Requirements for Water Surveying Scales in Hydrographic Monitoring
The standardization and requirements for water surveying scales in hydrographic monitoring are crucial for ensuring accurate and reliable data collection. These scales play a vital role in mapping and assessing the water bodies' features, including depth, temperature, salinity, and dissolved oxygen levels. The use of standardized scales helps to eliminate discrepancies and errors that could result from using different measuring devices or methods. Additionally, the requirements ensure that the scales meet specific safety standards, such as durability, accuracy, and ease of use. To achieve these standards, manufacturers must adhere to strict quality control measures during production. Furthermore, regular calibration and maintenance are essential to maintaining the accuracy of the scales over time. In conclusion, the standardization and requirements for water surveying scales in hydrographic monitoring are crucial for ensuring accurate and reliable data collection. By adhering to these standards, hydrographers can produce high-quality maps and reports that support various industries, including agriculture, transportation, and fisheries.

1. Introduction
1、1 Background
Hydrographic monitoring plays a critical role in various fields such as maritime navigation, environmental studies, and scientific research. It provides valuable information about the physical characteristics and dynamics of the oceans, including their temperature, salinity, currents, and depths. One of the key components of hydrographic monitoring is the collection and interpretation of water data using various techniques such as remote sensing, satellite imaging, and hydrometric surveys. Among these techniques, water surveying scales are widely used to measure the depth, width, and length of water bodies accurately. However, the accuracy and reliability of water surveying scales depend on their standardization and proper usage. In this paper, we discuss the standardization and requirements for water surveying scales in hydrographic monitoring.

2. Design and Construction of Water Surveying Scales
2、1 Types of Water Surveying Scales
There are several types of water surveying scales, including mechanical scales, electronic scales, and laser-based scales. Each type of scale has its advantages and disadvantages in terms of accuracy, durability, and cost. For instance, mechanical scales are simple and inexpensive but require manual adjustment, while electronic scales are more accurate but expensive to operate. Laser-based scales offer high accuracy but are complex and costly to install.
2、2 Design Principles
The design principles of water surveying scales include simplicity, robustness, accuracy, readability, and ease of use. A well-designed scale should be easy to read and interpret, even under varying lighting conditions. It should also be robust enough to withstand harsh environmental conditions such as seawater exposure, vibration, and impact. Additionally, a good design should ensure consistent readings over time by incorporating mechanisms for calibration and maintenance.
2、3 Construction Methods
The construction methods of water surveying scales can vary depending on their type and application. Mechanical scales are typically made from metal or plastic materials such as stainless steel or polycarbonate. Electronic scales may be constructed from specialized electronic components such as sensors, microcontrollers, and displays. Laser-based scales may incorporate optical components such as laser diodes and mirrors. Regardless of the construction method used, water surveying scales should be designed to meet the specific requirements of their application.
3. Calibration and Maintenance of Water Surveying Scales
3、1 Calibration Procedures
Calibration is a critical process that ensures the accuracy and reliability of water surveying scales over time. There are several methods forcalibrating water surveying scales, including manual calibration using known weights or pressure gauges
