This approach misses early degradation signals that occur between checks, with consequences such as:Missed drift: Thermocouple output gradually shifts due to oxidation and grain growth, causing hidden measurement error long before failure.Accuracy decline: RTDs maintain high accuracy near zero degrees Celsius but degrade as temperature moves away from reference points.Unplanned failures: ...
Tetra Tech’s Luke Stephenson, digital automation systems expert, shares how utilities can modernize infrastructure, improve resilience, and integrate emerging technologies. This article was originally published in Environmental Business Journal, Volume 38 Numbers 11/12: Q4 2025 Environmental Consulting & Engineering Industry. Luke discusses how utilities are ...
This pretreatment approach helps maintain measurement stability and accuracy during long-term online operation. • Automated system operation: A PLC-based control unit automates routine operating sequences including sampling control, water replacement and fault handling, reducing manual intervention and enabling unattended operation. • ...
Safety and compliance are fundamental in pharmaceutical manufacturing. From drug formulation to final packaging, each stage requires precision and strict adherence to international regulations. A critical element of achieving this safety is the use of SIL2 gas analysers for pharmaceuticals. These analysers ensure accurate gas monitoring, maintaining controlled atmospheres that prevent ...
Key technical considerations include:Load Distribution: The cantilever beam must be capable of bearing the load without excessive deflection. ...
The solution consists of four parts: sampling unit, preprocessing unit, control unit, and analysis unit. • Sampling Unit: Collecting the gas from coal-to-liquid process and introducing the gas into the laser gas analysis system. ...
Municipal Applications Water Distribution Systems: Monitoring and controlling potable water distribution in urban pipelines. Leakage Detection: Identifying leaks in water supply networks through precise flow monitoring. Irrigation Systems: Measuring and managing water usage in agricultural applications. 4. ...
Balanced Load Distribution When dealing with multiple loads or varying weights, it is essential to maintain a balanced load distribution. ...
Water treatment plants are undergoing unprecedented digital transformation. In 2024, DWTPs will continue to invest in automated technology-based plant management, streamlining their operations. First of all, digital transformation helps to centralize and control data management and therefore bring different DWTP processes together under one umbrella. These processes can be optimized using ...

Backflow is among the most common causes of failure in bubble diffusion systems. Learn how adding only a few inches of elastomer can eliminate backflow risks and optimize diffused aeration processes. For a steadily growing percentage of wastewater treatment facilities, bubble diffusion systems are the centerpiece of an efficient, reliable, and thorough aeration ...
Automated Meter Reading: Electronic DC energy meters have the ability to perform automated meter reading functions by transmitting energy data to computers or power monitoring systems via data communication interfaces. This greatly reduces the costs and errors associated with manual meter readings, while also increasing the efficiency and accuracy of meter readings. 6. ...
When implemented in a loop or generator, the instrument can prevent further system and product contamination. Figure 4. Continuous monitoring of Purified Water distribution system. ...
Although the origins of world Laboratory Day are still unclear, it gives us a chance to reflect on the great achievements and breakthroughs in scientific research.At Techcomp, we are delighted to celebrate World Laboratory Day and to play our part with a suite of world-class laboratory products across Molecular Spectroscopy, Chromatography, Mass Spectroscopy, Gas Sensing, Precision Weighing, and ...
Overview The accurate measurement of cooling tower blowdown water flowing at irregular intervals prior to reinjection into a caprock well became a stubborn problem for Covanta Energy Corp at the Honolulu H-POWER Facility on the island of Oahu, HI. The irregular flow intervals created foam and bubbles in the line, which required a next- generation flow meter solution. Jeff Vaughan, chief ...
Overview When plant engineers at Grupo Suzano of Brazil’s pulp and paper plant in Sao Paulo Brazil noticed irregular measurements of plant intake water drawn from a nearby river, there was immediate cause for concern because it threatened the plant’s productivity. Grupo Suzano is a diversified Brazilian company that produces over one million tons of paper annually, which is sold in ...
Which Purafil monitoring solution is the best for your facilities? The short answer is, it depends. While both OnGuard Devices and Corrosion Coupons utilize copper and silver metal to measure the corrosivity of the surrounding air, there are a number of factors that will determine which one your facilities will benefit most from. It is also important to note that corrosion occurs faster at higher ...
As you read this blog, thousands of pH measurements are being performed around the world. They often adhere to the same pattern: manual sampling followed by laboratory analysis — meaning inherent disadvantages including increased time expenditure. In contrast, production processes typically require complex analytical techniques and equipment to obtain highly accurate results used for ...
Banks have the highest level of security among critical U.S. industries, yet by some estimates, financial Services companies are hundreds of times more likely to be the target of cyber attacks, and the situation is getting worse. No financial services company wants to generate these kinds of headlines regarding their cybersecurity. In addition to that, a new US rule orders banks to promptly flag ...
In the first part of this series, a brief historical overview was given for both infrared (IR) and near-infrared (NIR) spectroscopy, as well as for Fourier transformation (FT) and dispersive spectroscopy. A few myths were discussed and put to rest, and we showed that Fourier transformation spectroscopy (FT-NIR) is not necessarily the only nor the best way to integrate reproducible spectroscopic ...
Before the onset of the industrial revolution, industry owners had to employ a batch of hardworking and competent workers to ensure that all the products were designed in an accurate and efficient way. However, the introduction of electric instruments and machines transformed the way businesses and industries[1] operate. Everyday products and resources like clothes, books, furniture, and more ...
