When both a variable frequency drive (VFD) and a control valve are available as operational tools, liquid level control systems are often designed with two single-loop controllers, LIC1 and LIC2, as shown in the diagram above. As many of us know, when there is one controlled variable and two manipulated variables, several control strategies are

Measurement testing, also known as metrology, is the science of measurement, which involves the process of determining the physical properties or parameters of an object or substance through a series of precise tests. In physics, this often refers to the use of specialized instruments to measure objects according to specific, standardized procedures. It includes activities

Introduction In chemical engineering, the use of fluorine-lined valves is essential for handling corrosive and high-purity water conditions. The primary materials used for fluorine lining are Polytetrafluoroethylene (PTFE) and Perfluoroalkoxy Alkane (PFA). This article provides a detailed comparison between PTFE and PFA in terms of chemical stability, electrical insulation, wear resistance, non-stick properties, hardness, temperature

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
