Read more >Clamp-on ultrasonic flow measurement technology represents a significant advancement in the monitoring and management of fluid flow within various industrial processes.
This non-intrusive technique involves attaching ultrasonic transducers to the outside of the pipeline, and by emitting ultrasonic signals through the pipe and fluid, it measures the time it takes for the sound waves to travel with and against the flow. The difference in these times is used to calculate the flow rate, offering a highly accurate, reliable and maintenance-free method for measuring fluid flow, including gases.
The challenge of accurate flow measurement in chemical production:
A practical application of this advanced technology can be observed in the chemical production processes at a plant located in Stade, Germany, which utilises rock salt from nearby deposits in Ohrensen to produce hydrogen and caustic soda through electrolysis. Chlorine, a by-product of this process, serves as a critical raw material for several other production stages within the facility. One notable application involves the production of methylene diphenyl-diisocyanate (MDI), a key precursor in manufacturing polyurethane. Polyurethane’s versatility is evident in its use for thermal insulation, sportswear, and as a high-tech adhesive in the automotive industry.
The non-intrusive solution:
Faced with the challenge of inaccurate flow measurements due to equipment vibration, and needing a solution that wouldn’t disrupt production, the plant turned to Flexim’s clamp-on ultrasonic technology – a solution already proven across various applications within the plant. The deployment of flowmeters for the non-intrusive flow measurement of hydrochloric gas was initiated with Flexim’s portable flowmeter confirming the viability of this approach, leading to the installation of the stationary system.
Ensuring continuous operation:
Clamp-on ultrasonic flow measurement technology not only resolved the immediate issue by replacing a malfunctioning meter without halting production, but also offered the flexibility to adapt to future needs without disrupting operations. Following initial tests, adjustments were made by switching to higher-frequency transducers, ensuring reliable, ongoing measurement of hydrogen chloride levels essential for the downstream production processes.
The successful implementation of clamp-on ultrasonic flow measurement technology in a critical production process exemplifies innovation and adaptability in industrial applications, securing continuous operation and product supply.
