A Real UPS Failure Case Study and What We Learned In instrumentation and control systems, the UPS is often called the “heartbeat of the plant.” It keeps critical systems like DCS, field instruments, and control loops running—even during power disturbances. Most of the time, everything looks fine during routine inspection.But one real incident reminded us […]

In industrial environments, especially during the installation of radar level gauges, level switches, or other instrumentation devices, you will often come across the abbreviation SORF. Many engineers encounter this term on technical drawings or in technical specifications, such as “DN80 SORF PN16” or “2” 150LB SORF”. But what exactly is a SORF flange? Why is
What is SORF Flange and Why Is It Widely Used in Instrumentation Applications? Read More »
In industrial environments with acid-base corrosion, instrumentation gas supply lines (such as compressed air pipelines) are highly susceptible to damage from acid mist, splashes, or volatile gases. This can result in gas leakage, contamination, and disruptions to the normal operation of instruments. Therefore, it is crucial to implement protective measures across various aspects of materials
In the world of instrumentation, thread connections are a fundamental part of installation, maintenance, and repair. From installing pressure gauges to connecting valves and fixing instruments to pipelines, the correct choice and installation of threads directly impact the seal integrity, safety, and longevity of the system. As an instrumentation engineer, mastering commonly used thread specifications

In steam flow measurement, vortex flow meters are commonly used due to their reliability and simplicity. However, when temperature and pressure compensation is not properly implemented or installation points are wrongly selected, even small errors can lead to significant measurement inaccuracies. This article provides an in-depth overview of the underlying logic of temperature and pressure
As a vital part of the automation industry, PLC engineers face various challenges during commissioning and troubleshooting in the field. However, due to a lack of experience or simple oversight, engineers often make some reckless decisions that can significantly impact system performance or even cause safety hazards. These “fatal” mistakes can not only prevent smooth

Vortex flow meters are widely used for measuring steam, gas, and liquid flow in industrial applications due to their simple structure, good stability, and low maintenance requirements. However, during operation, users may occasionally encounter situations where the flow meter shows a minimum reading or no output signal at all. This problem can be caused by
Displacer level transmitters are widely used in industrial applications such as oil tanks, chemical vessels, and storage tanks because of their stable structure and reliable measurement. However, during long-term operation, users may sometimes encounter a situation where the indicated level is significantly higher than the actual liquid level. This issue may be caused by mechanical
