In industrial systems, two devices are often used to monitor flow: the Flow Meter and the Totalizer. While they’re related, they serve different purposes. Confusing the two can lead to wrong equipment selection, costing time and money. If you’re in process control, palm oil production, water treatment, or factory automation in Malaysia—this guide is for

If your digital panel meter suddenly shows zero, your PLC input flatlines, or your transmitter stops responding — you might be experiencing 4-20mA signal loss. This is one of the most common issues faced in factories, refineries, and automation systems across Malaysia. Let’s break it down in simple terms. First, What Is a 4-20mA Signal?

When it comes to precision pressure monitoring, Setra Systems is a trusted global brand—and proudly distributed by Celectric right here in Malaysia. From HVAC to cleanrooms and even industrial automation, Setra’s sensors are known for reliability, accuracy, and longevity. But what industries in Malaysia are using Setra pressure transmitters most? Let’s break it down. 1. HVAC

In today’s smart factory environment, having accurate, real-time display of readings like pressure, flow, temperature, or level is no longer a luxury—it’s a necessity. That’s where Digital Panel Meters (DPMs) come in. But with so many brands and models out there, how do you choose the right one for your industrial setup in Malaysia? Let

Vortex Flow Meter can be used for a wide range of fluids, i.e. liquids, gases and steam. They are to be seen as first choice, subject to verification to cover the requirements of a particular application. Vortex meters are essentially frequency meters, since they measure the frequency of vortices generated by a “bluff body” or

For any magnetic flowmeter to function correctly, it must have three connections (including a ground) to the process liquid passed from the magnetic flow tube onto the magnetic flow transmitter. About 80 percent of the time, problems with the flow measurement readings provided by a magnetic flowmeter can be traced directly to improper solution ground

In the dynamic landscape of industrial processes, efficiency is paramount. Whether you’re managing chemical production, food processing, or any other manufacturing endeavor, the precision of your operations is crucial. This is where batch controllers step in, offering a streamlined solution to optimize your production cycles. Understanding Batch Controllers Batch controllers are automated systems designed to

Hysteresis is a common occurrence in various physical systems, including pressure sensing. It describes the delay or lag in a physical response to changes in external conditions or forces. In the case of pressure sensing, hysteresis can cause the diaphragm within the sensor to not immediately return to its original position after pressure changes. This

What is Magnetic Flow Meter A magnetic flow meter (mag meter, electromagnetic flowmeter) is a transducer that measures fluid flow by the voltage induced across the liquid by its flow through a magnetic field. A magnetic field is applied to the metering tube, which results in a potential difference proportional to the flow velocity perpendicular to the flux

Vortex flow meters are widely used in various industries for measuring the flow of liquids, gases, and steam. Calibration is essential to maintain their accuracy and performance. Here’s why water is commonly used for calibrating these flow meters. 1. Universality of Water Water is a universal fluid, readily available and widely used in calibration processes

There are many types of Electrical and Mechanical Sensors in the market. Still, all pressure sensor infer pressure by measuring a physical change within the sensor when exposed to pressure changes. This physical change can be resistance, capacitance, or frequency. Here would like to review all types of Pressure Sensors used with industrial pressure transmitters, explain of the sensor, hence advantages, and

Selecting a low differential pressure transducer (DPT) for critical care ventilation is one of the most important decisions mechanical designers, engineers, and architects can make. These transducers perform precise monitoring and contamination control of isolation room pressures in critical environments. When properly selected and installed, they help prevent communicable diseases like tuberculosis (TB). The positive

A capacitor is a two-terminal device that consists of two conducting bodies separated by a non-conducting (dielectric) material. Below is a simple capacitor consisting of two plates. To create a more usable geometry for sensors, the electrodes can be arranged in various ways. Though this complicates the above expression for capacitance, the overall relationship between

Due to the obsolescence of several components used in the production of Contrec 505 Series Instrumentation, Contrec Manufacturing has made the decision to promptly transition the 505 Applications to the advanced 515 platforms, effective from May 2019. The main benefits are for 515 platforms are: Same instrument housing, display and operator interface Selectable analog or

Contrec New 424 Batch Controller & 425 Flow Computer Contrec never stands still and always looking for innovative ways to make good flowmeters even better. When Contrec’s 414 Batch Controllers and 405 Flow Computers were first released in 1992, they quickly became the industry standard for accurate and reliable flow monitoring and control. So good
