A differential pressure gauge measures the difference in pressure between two points in a system and presents the subsequent differential pressure directly on a single gauge dial. Ashcroft has specialized in pressure instrumentation since 1852. As a leader in our field, we are often asked to provide information to individuals looking for a foundation of knowledge on this subject and more. Read on to learn where basic definitions related to differential pressure, where the gauges are used, how they work, and common applications. When you're done reading, you will also find additional resources that may interest you.

If you work in an industry with harsh process environments like oil and gas, water and wastewater and others, you know that liquid and gas flow measurement is critical to ensuring your operation runs safely and efficiently. You also know that purchasing a flow meter to perform this function can cost you thousands of dollars. One popular and very effective alternative is to configure a differential pressure (DP) gauge to measure flow. This simple step can deliver the same results and save you money. In this article, you will learn the basic concepts of fluid dynamics and pressure distribution based on Bernoulli’s Principle. You will also see why DP gauges are ideal for monitoring flow in harsh environments and how easy it is to configure these instruments to meet your specific needs. Since 1852, Ashcroft has been an industry leader in measurement instrumentation. As a product marketing leader, I am happy to share information that can help you discover solutions to your complex challenges. When you are finished, you will know how to configure your DP gauge to measure flow and be guided to other helpful resources that can help you find the right DP gauge for the job.

When you’re monitoring differential pressure in applications where high static pressure and low differential pressure is a requirement, reliability and corrosion resistance is essential for instrumentation to operate safely. If your pressure measuring instruments aren’t compatible with your process, you may face equipment damage and downtime. This blog will compare Ashcroft’s 5503 and F5504 differential pressure gauges and discuss their features and benefits to help you find the best solution for your needs.
