Industrial Instrument Failure During Storms: How to Prevent Water Ingress, Signal Drift and System Shutdowns

Instrumentation /

Extreme weather conditions such as typhoons, hurricanes, heavy rain, and thunderstorms can seriously challenge industrial instrumentation systems. For instrumentation engineers, a storm is not only a weather event — it is also a reliability test for field instruments, control systems, and electrical protection. During severe weather, problems such as water ingress, unstable signals, communication failures, […]

Target Flow Meter Signal Problems: Troubleshooting Guide for No Output and False Output

Flow meter /

Target flow meters are widely used for measuring challenging media such as high-viscosity fluids, slurry, liquids containing particles, and media prone to scaling. Compared with conventional flow meters, they are known for their excellent resistance to harsh operating conditions. However, like any industrial instrument, target flow meters can also experience signal problems during operation. Among

Magnetic Flow Meter Grounding Rings Explained: Why They Are Needed and How to Install Them Correctly

Flow meter /

Introduction A magnetic flow meter (also called an electromagnetic flow meter or mag meter) measures flow based on Faraday’s Law of Electromagnetic Induction. Because the measurement signal generated by the electrodes is only at the millivolt level, the instrument is highly sensitive to: Ground potential differences Stray currents Electrical noise Improper grounding Static electricity interference

Static Bonding Explained: Why Flanges and Equipment Enclosures Need Bonding Jumpers

Instrumentation /

Difference Between Static Bonding and Static Grounding in Industrial Facilities In chemical plants, oil and gas facilities, pharmaceutical factories, coating systems, and powder handling processes, small metal bonding wires can often be found across pipe flanges, equipment doors, and removable covers. Many people assume these wires are simply “grounding cables.” However, their actual purpose is

Magnetic Level Gauge: Working Principle, Advantages and Industrial Applications

Level meter /

A magnetic level gauge (MLG), also known as a magnetic level indicator, is a reliable mechanical liquid level measurement device widely used in chemical, oil & gas, power, pharmaceutical, and water treatment industries. Unlike differential pressure level transmitters or radar level meters, magnetic level gauges measure liquid level through a magnetic coupling principle, providing direct

Magnetic Flow Meter vs Coriolis Mass Flow Meter: How to Choose the Right Flow Measurement Solution?

Flow meter /

Introduction When selecting a flow meter, many engineers and buyers face the same question: Should I choose an electromagnetic flow meter or a Coriolis mass flow meter? Some people think: “Magnetic flow meters are cheaper, so they must be the better choice.” Others believe: “Coriolis flow meters are more accurate, so they are always the

Why CT Secondary Cannot Be Open and PT Secondary Cannot Be Shorted?

Instrumentation /

A Practical Guide to Current Transformers and Voltage Transformers Many engineers know the basic definition: CT measures current PT measures voltage This statement is correct, but in real electrical systems, this understanding is not enough. Both Current Transformers (CTs) and Potential Transformers (PTs), also called Voltage Transformers (VTs) are used to convert high-voltage system parameters

When Should a Venturi Flow Meter Use a Pressure Averaging Ring?

Flow meter /

Introduction Many engineers know that a Venturi flow meter works by measuring the differential pressure generated between the inlet section and the throat section. However, when it comes to special applications — such as high-pressure oxygen, dirty gas, slurry, black water, or systems with limited installation space — one important design question often appears: Should
