Steam flow measurement for billing 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.

Product Solutions
The Flexim FLUXUS G722 ST-HT measures superheated steam up to temperatures of 630 °C (1166 °F) non-intrusively from the outside of the pipe. This unique flow measurement solution is based on the correlation flow measurement principle. The acoustic measuring method has exceptionally high measuring dynamics and functions independently of the flow direction. The FLUXUS G722 ST-HT offers precise bi-directional flow measurement over a turndown ratio of up to 10:1. This innovative flow meter is not in direct contact with the steam and doesn't have any moving parts, so is not subject to wear and tear, which saves on essential maintenance cost. Its installation can be carried out without interrupting the process, which makes it a highly cost-efficient retrofit solution.
- No pressure loss, no pipe modification, no process interruption.
- High dynamic flow range.
- Easy and cost-efficient retrofit.

Flexim WaveInjector technology enables metering at extreme temperatures from -328°F up to 1166°F. Using patented technology, the Flexim WaveInjector thermally separates the ultrasonic transducers from the hot or cryogenic pipe, allowing permanent flow measurements at extreme pipe wall temperatures providing the ultimate competitive edge - in process control, process management, and environmental protection. The WaveInjector, along with the ultrasonic transducers, is simply installed on to the outer surface of the pipe, using coupling plates for a proper acoustic contact. This means, that there is no need to open the pipe - no drilling, and no process shut-down is required.
- Increased operator and plant safety.
- Increased environmental compliance.
- Easier plant start-ups and upgrades.
