Many people think dust is just a housekeeping problem — dirty floors, clogged equipment, or poor workshop conditions. But in industries handling combustible powders, dust can become far more dangerous. When fine particles become suspended in the air and encounter sparks, static electricity, hot surfaces, or friction heat, what looks like an ordinary layer of […]
Project Background A customer in Taiwan required two inline thermal mass flow meters for industrial gas monitoring applications. The project involved different gases and operating conditions, including nitrogen (N₂) and natural gas measurement. The customer required: Stable low-flow gas measurement Compact inline installation RS485 communication Explosion-proof protection Local LCD display with totalizer High temperature resistance

Common Causes of Zero Drift and Practical Solutions Anyone working in instrumentation has probably encountered this problem: Low differential pressure transmitters and micro-pressure transmitters are among the most unstable instruments in industrial sites when it comes to zero drift. This is especially common in applications such as: Furnace draft pressure Air duct micro-pressure Clean room
Why Do Low Differential Pressure Transmitters Drift? Read More »
In industrial automation projects, one question comes up again and again: Should the system use only an HMI, or should it be designed with a SCADA system from the beginning? At first, the difference may not seem important. During commissioning, both solutions can appear to work fine. Operators can start and stop equipment, view process

Environmental equipment suppliers often claim that: Wet FGD systems can achieve more than 95% SO₂ removal efficiency SCR DeNOx systems can reach 80% NOₓ reduction or even higher But once the project is actually commissioned, the biggest challenge is often not whether the technology works in theory — it is whether the entire system can

A pressure transmitter may leave the factory fully calibrated, thoroughly tested, and perfectly within specification. Yet once installed on site, it suddenly starts giving unstable readings, drifting values, or inaccurate measurements. Why? In many cases, the problem is not the instrument itself — it’s how the transmitter is selected, installed, and applied in real operating

In chemical production, alarm and interlock settings for reactors are never just simple numbers. If the setpoint is too low, the system alarms frequently, disrupting production and eventually causing operators to ignore warnings — the classic “alarm fatigue” problem. If the setpoint is too high, by the time the alarm is triggered, the incident may

Selecting a reliable flow meter for large diameter circulating water pipelines (starting from DN400 and extending to DN2000 or even larger) has never been an easy task. For small and medium pipe sizes (generally below DN400), electromagnetic flow meters are usually the preferred choice because they offer a good balance between accuracy and reliability. If

Introduction In industrial automation, instrument air quality is critical. Compressed air is not just “pressurized air”; it may carry moisture, oil mist, particles, and condensate. While these impurities may be acceptable for cleaning or pneumatic tools, they can cause malfunctions in instruments and control systems. 1. Factory Air vs. Instrument Air Factory air, also known

1. How Radar Level Meters Measure Liquid Level Radar level meters use the Time-of-Flight (TOF) principle: the transmitter emits a microwave pulse, which reflects off the liquid surface and returns to the sensor. The instrument calculates the distance based on the round-trip travel time. Formula: D=c×t2D = frac{c times t}{2} where: DD= distance to
