Introduction Smart Water Management (SWM) refers to the integration of modern technologies such as the Internet of Things (IoT), big data, cloud computing, and artificial intelligence (AI) to digitalize and intelligently upgrade water supply, drainage, wastewater treatment, and water resource management. The goal is to improve efficiency, reliability, and sustainability in water systems. 1. Core […]

Introduction Communication is an essential aspect of data transfer in computing and electronics. Two primary methods of data transmission are serial communication and parallel communication. Understanding the differences, advantages, and applications of each helps in choosing the most efficient approach for a given system. 1. What is Serial Communication? Serial communication is a data transmission

The positive leg of a Type K thermocouple consists of a nickel-chromium alloy, while the negative leg is made of a nickel-silicon alloy. The temperature-dependent behavior of a Type K thermocouple is as follows: Low-Temperature Stage (-200°C to 0°C) Electron Migration Suppression:At low temperatures, atomic thermal motion is reduced, making it harder for electrons to

In industrial systems, the management of liquid levels is crucial to the safe and efficient operation of equipment. One critical aspect of this is the use of low-low liquid level interlocks, which are designed to protect systems from damage due to low liquid levels. These interlocks automatically activate certain protective measures when the liquid level

Choosing the correct type of fire extinguisher for instrument rooms and power distribution rooms requires careful consideration. These areas typically house electrical equipment and precision instruments, making them susceptible to Class E fires, which involve energized electrical equipment. I. Fire Extinguishers for Power Distribution Rooms According to the “Design Code for Building Fire Extinguisher Installation”

Introduction Combustible gas detectors play a crucial role in various industries, including metallurgy, petroleum, chemical engineering, coal mining, municipal gas management, storage, transportation, hospitality, and fire prevention. These devices monitor the concentration of combustible gases in the air and trigger an alarm when dangerous levels are detected, preventing fires and poisoning incidents. Many customers often

Introduction Automation instruments play a dual role in chemical production, serving as the “eyes of the process” and the “nervous system of control.” Their reliability directly impacts production safety, efficiency, and product quality. However, instrument failures and unexpected shutdowns remain common and costly issues in the industry. To mitigate high repair expenses and production losses,

In the field of instrument calibration and testing, there are clearly defined categories, contents, and characteristics. However, for those unfamiliar with the metrology industry, these concepts may seem unclear. This article will provide a detailed introduction to the core concepts of instrument calibration and testing, including its content, classification, and features. Content of Instrument Calibration

Introduction In hazardous environments where explosive gases, vapors, or dust are present, electrical installations must adhere to strict safety standards to prevent ignition sources. One of the key considerations in such installations is whether to use flexible conduits. While they are not always mandatory, flexible conduits are often required in specific situations to ensure safety

Introduction In modern industrial automation, Configuration and Human-Machine Interface (HMI) are two fundamental concepts that play a critical role in intelligent control systems. While these concepts might seem straightforward, their functionalities are profound and indispensable. This article provides an in-depth exploration of these concepts, discussing their definitions, functions, key technical features, and widespread applications in
