In modern chemical and process industries, corrosion remains one of the key challenges affecting production stability, instrument reliability, and plant safety. Piping systems, flow meters, level transmitters, and process sensors are often exposed to various acids, bases, solvents, and gas-liquid mixtures, many of which can chemically corrode wetted materials. Understanding the corrosion characteristics of different
1. Boiler DCS Displaying Multiple Faulty Parameters, Leading to Shutdown Fault Diagnosis:Upon inspecting the DCS display, it was found that the parameters such as steam drum level, feedwater flow, main steam flow, and deaerator water level were all showing as faulty points. Based on experience, it was judged that the issue likely lies with the

Bus-type instruments (e.g., HART, FF, Profibus-PA) and 4-20mA instruments are two mainstream signal transmission solutions in industrial automation. While they share certain functional connections, they also have essential differences: Core Differences Signal Type 4-20mA Instruments: Analog signal (continuous current signal, only transmitting a single variable). Bus-Type Instruments: Digital signal (data packets, can transmit multiple variables

1. Introduction In modern industries such as fine chemicals and pharmaceuticals, precise solution preparation is critical. However, traditional measurement methods often face a common challenge: How can we accurately measure the solute content in a solution without complex analyzers? Coriolis mass flowmeters provide an efficient solution by enabling a shift: 👉 From fluid measurement →
1. Introduction In industrial automation systems, one of the most common yet confusing issues is: Why does the value displayed in the DCS system differ from the field instrument reading? This discrepancy is not just a minor technical issue—it can directly impact process control accuracy, operational safety, and decision-making. Understanding the root causes and applying

The Engineering Principles That Determine Equipment Reliability In industrial systems, most failures are not caused by major components—but by something much smaller: 👉 Fasteners Bolts, nuts, and screws may seem simple, but they directly determine whether a system remains stable—or fails. And here is the key reality: 👉 Most fastening failures are NOT caused by
