Vortex flow meters are widely used across industrial automation due to their simple structure, wide turndown ratio, and strong adaptability. They are commonly deployed for measuring liquids, gases, and steam.However, in real operating environments, vortex meters may occasionally suffer from pulse loss — a condition where part of the vortex shedding signals generated by the […]
Radar level transmitters have become one of the most reliable technologies for liquid and solid level measurement. With advantages such as non-contact measurement, high accuracy, strong anti-interference capability, minimal maintenance, and long service life, radar instruments are now widely used across process industries. Among various radar frequencies—6GHz, 26GHz, 80GHz, and even 120GHz—the 26GHz and 80GHz

Contactors and relays are two essential components in electrical control systems. While they share similar working principles and both function as switches controlled by an electromagnetic coil, they differ significantly in their applications, design, and capacity. Below is a detailed explanation of their differences and specific use cases. 1. Function and Purpose Contactors Primary Use:

In gas detection and safety-instrumented applications, the choice of signal transmission method is not just a design preference—it directly affects the Safety Integrity Level (SIL) and the overall reliability of the safety protection layer. As fieldbus technologies become more common in process plants, a frequently debated question has emerged: Can a Gas Detection System (GDS)
According to GB 50493 (Design Standard for Combustible and Toxic Gas Detection and Alarm Systems) and general industrial safety design practices, GDS detection units must use independent point-to-point wiring when transmitting signals to the alarm controller.Bus (multi-drop shared line) communication is not permitted for safety-critical gas detection functions. The core purpose of a GDS is

In industrial measurement and control, pressure transmitters are everywhere. But in vacuum systems, environmental monitoring, and high-precision applications, you may notice that engineers prefer absolute pressure transmitters instead of the more common gauge pressure transmitters. At first glance, they look similar, but the reference point and measurement logic behind them are fundamentally different: Gauge pressure

In modern industrial automation, digital communication protocols such as Modbus, Profibus, and HART have become increasingly popular. Yet, despite these advances, the 4–20 mA analog signal remains one of the most reliable and widely used methods for transmitting process variables such as pressure, temperature, flow, and gas concentration. From gas detection systems (GDS) to level
