Industries involving liquids such as chemical/petrochemical, oil and gas, and water/wastewater, are constantly challenged by corrosion. Understanding the different types of corrosion and how they occur is the first step in protecting your process instruments from its damaging effects. As a leading authority in pressure and temperature instrumentation, Ashcroft® offers valuable insights into corrosion and its impact on businesses. This article explores the different types of corrosion, the factors influencing corrosive environments, and the significance of selecting compatible materials for process instrumentation. Additionally, discover key considerations for choosing pressure instrumentation capable of withstanding harsh corrosive conditions.

According to the Environmental Protection Agency (EPA), groundwater serves as a crucial resource for half of the U.S. population. Reliance on this vital natural resource is especially significant in regions with scarce rainfall, limited surface water availability, or high agricultural demands and population. As a leading manufacturer of pressure and temperature instrumentation, Ashcroft understands the challenges of protecting this vital resource. In this article, you will learn about submersible pressure transmitters and how they are used to monitor water levels and provide essential information to water management personnel. You will also see examples of four common applications where submersibles are used and some challenges these instruments may encounter while in use. When you are done reading, you will find additional, related resources that may be of interest when you are ready to go beyond the basics of this topic.

Whether you use industrial storage tanks for harvesting rainwater, providing municipal drinking water, irrigating fields, emergency fire suppression, or other purposes, you know how important it is to maintain accurate tank level pressure. One reliable solution is a pressure switch. This instrument is known for its accuracy, repeatability and versatility in water level management applications in water treatment systems, bubblers, scrubbers, and more. But how do they work? Ashcroft has been manufacturing pressure switches for decades and understands the unique challenges of pressurized tank systems. In this article, you will see how a pressure switch works and learn how multiple tank levels can be monitored and controlled using one or more pressure switch connections. When you are done reading, you will also find additional resources to answer other switch-related questions you may have.

Anyone working in the water/wastewater industry knows just how important it is to maintain accurate and reliable pressure measurements throughout the process. Without the proper instrumentation to do the job, your operation is at risk for pump damage, clogging and other issues that could bring the entire system to a halt. At Ashcroft, it is our business to know the challenges you may encounter to keep your operation running safely and effectively and to provide solutions that will address your specific needs. In fact, in my 30 years of experience, I have seen just about everything that can go wrong (and right) in water/wastewater applications. In this article, you will get an overview of common water/wastewater application issues, and learn how the proper instrumentation, including isolation rings and accessories, can help you prevent these issues from happening to you. Throughout the article, you will also see links to additional resources that you can use as a reference to answer other questions you may have. Let's get started.

If you experiencing issues with diaphragm seal failure in your process, you are not alone. In harsh applications that involve corrosive media and other challenging conditions, diaphragm seals are your primary line of defense in protecting your pressure instruments from becoming damaged. At Ashcroft, we've seen practically every scenario that can cause a diaphragm seal to fail, leading to inaccurate readings and costly downtime. In this article, we will review how a diaphragm seal works, explore the three conditions that account for the majority of diaphragm seal failure — corrosion, high temperature, and fluid fill leakage — and offer some corrective measures to fix these issues. When you are done, you will have a better understanding of why diaphragm seals can fail and be able to identify and prevent potential issues in your own process. You will also find links to additional resources that will help address other diaphragm-related questions you may have.

Isolation rings are also known as isolators. They are designed to protect pressure-measurement instruments from the damaging effects of corrosive media in water/wastewater treatment plants, chemical processes, and mining facilities. To fully appreciate the importance of using these instruments in your operation, we need to start with a basic understanding of how they work. Ashcroft has been in the pressure and temperature instrumentation business since 1852, and we wrote this article for the industry novice. We hope you can use it as a foundation for understanding the important role isolation rings play in challenging applications. Read on to learn how isolation rings protect pressure-sensing instruments in your applications, the three most common types of rings, how they are constructed and the primary benefits of using these instruments.
