Differential-pressure (DP) level measurements are widely used in chemical and petrochemical facilities, thanks to their reliability and ease of use. Recent advances are making them even more reliable and easy to use
Differential pressure (DP) level-measurement technology (Figure 1) is the most commonly used approach in the chemical process industries (CPI), thanks to its reliability, ease of use and adaptability to a variety of applications. While there are many benefits to working with DP measurement on level-measurement applications, there are some drawbacks, as well. Fortunately, several new advances in the design of seals and sensors, as well as new manufacturing techniques for filling remote-seal systems, are expanding the functionality of DP level systems into applications that previously required alternative level technologies. These advances are also improving the reliability of DP level measurement in existing applications and making it even easier to install.
