Introduction Orifice plates and flow nozzles are two widely used primary elements in differential pressure (DP) flow measurement systems. Although both devices work based on the same principle — creating a pressure difference by restricting fluid flow — many engineers still face difficulties when selecting the right solution for a specific application. Should you choose […]
Magnetic level gauges are widely used for liquid level indication in chemical plants, oil storage facilities, water treatment systems, and other industrial processes. Their simple mechanical design, local visual indication, and ability to operate without an external power supply make them a practical solution for many storage tanks and process vessels. However, not every magnetic

Introduction Online monitoring instruments are automated measurement systems that use sensors, signal processing technology, and communication networks to continuously monitor industrial and environmental parameters in real time. Unlike traditional manual measurement methods, online monitoring systems can collect, analyze, and transmit measurement data automatically, helping industries improve process control, safety management, and operational efficiency. Modern online
Temperature sensors are widely used in industrial automation, process control, medical equipment, and household applications. They play an important role in monitoring and controlling temperature in various systems. However, temperature sensors may experience inaccurate readings, unstable signals, or complete failure due to electrical problems, environmental conditions, improper installation, or aging components. Understanding the common causes

In industrial automation systems, wiring short circuits are one of the most common electrical faults that can cause instrument failure, signal interruption, equipment damage, or even safety risks. A short circuit occurs when two points in an electrical circuit that should remain separated become unintentionally connected. This creates a low-resistance path, causing excessive current flow
Introduction For engineers working on Safety Instrumented Systems (SIS), one question will eventually come up: What SIL level is required for this SIF loop? Safety Integrity Level (SIL) is a key parameter used to define the risk reduction capability of a Safety Instrumented Function (SIF). It determines the required reliability level of safety-related components, including
What Are the SIL Levels of a SIF Loop? A Complete Guide to SIL1, SIL2, SIL3 and SIL4 Read More »
How entrained air, gas bubbles, cavitation, and changing flow patterns affect industrial flow measurement accuracy. In an industrial liquid pipeline, the pump operates at a constant speed, the control valve remains in the same position, and the process appears stable. However, the flowmeter reading suddenly increases, drops, or fluctuates continuously. The pressure transmitter may show

Understanding Thread Sealing Requirements for Explosion-Proof Conduit and Cable Gland Connections During explosion-proof electrical inspections, engineers often find the same installation practice: PTFE thread tape (commonly known as thread seal tape) is wrapped around galvanized conduit threads, and sometimes it is also applied to explosion-proof cable gland threads. The reason given by installers is usually

Glycerin, also known as glycerol, is widely used in the chemical, pharmaceutical, food processing, cosmetics, and biodiesel industries. Its relatively high viscosity and concentration-dependent physical properties can make flow measurement more challenging than measuring water or other low-viscosity liquids. A common question from engineers and plant operators is: Can an electromagnetic flow meter be used
