Steam measurement at a sulphuric acid plant

Heat recovery systems (HRS) in sulphuric acid plants uses the heat of absorption and dilution to generate steam. However, accurately monitoring and billing the flow of steam, which is a vital component in this industrial process, can be challenging, especially when dealing with temperatures exceeding 300 °C. 
Traditionally, the industry relied on conventional methods involving differential pressure measurements and measuring orifices. While effective, these methods had drawbacks, including maintenance-related disruptions and energy loss. A non-intrusive solution that offers two distinct systems for various temperature ranges is advantageous.
