Everyone managing a part of a production plant for the petro-chemical industry wants to maintain a continuous and high output, safely and efficiently. Having control information from instrumentation is essential, as it provides the necessary adjustments needed to keep the output steady. However, (un)scheduled downtime due to pressure measurement failure or unreliable or failing measurements seems unpreventable and are cumbersome to fix, especially with pressure being the most measured entity. And managing this day-to-day cause of stress, often takes the focus of structural and long-term improvements. To what extent those issues slow your processes down and consume your valuable time depend heavily on who you select to be your service provider. Choosing the right supplier allows you to focus on activities that add value to your business and maintain the promised process output.
