Surface Acoustic Wave (SAW) Technology: Advanced Flow Measurement and Biofilm Prevention in WFI Loops
Key points
Bürkert, a leader in flow control solutions, has introduced an innovative flowmeter that employs Surface Acoustic Wave (SAW) technology. This device is specifically engineered to improve flow measurement accuracy while also preventing biofilm buildup in Water for Injection (WFI) loops. Tailored for the pharmaceutical sector, Bürkert’s Type 8098 FLOWave flowmeter offers highly precise, contactless flow measurement, significantly reducing the risk of contamination caused by inadequate flow conditions.
State-of-the-Art Flow Measurement Technology
The FLOWave flowmeter operates using surface acoustic waves (SAW) that travel through the fluid. By analyzing the time differences between these waves, FLOWave can accurately determine real-time volume flow rate, cumulative volume, flow velocity, and temperature—unaffected by fluid conductivity or trapped bubbles. This groundbreaking technology facilitates precise, continuous monitoring of flow parameters in WFI systems, ensuring adherence to strict pharmaceutical regulations.
Performance and Accuracy
Bürkert’s FLOWave flowmeter stands out for its precision, achieving measurement accuracy within 0.4% and repeatability within 0.2%. Such accuracy is vital for maintaining minimum flow rates and turbulence, which are essential for preventing biofilm formation in WFI systems. Additionally, the careful regulation of flow velocity and temperature guarantees optimal system performance, minimizing the likelihood of biofilm growth.
By enhancing flow management, the FLOWave flowmeter boosts pump efficiency, avoiding unnecessary increases in pump speeds that could lead to higher energy use and accelerated wear on the pump. This results in lower operational costs and extended system lifespan.
Reliable, Contactless Measurement
The FLOWave flowmeter utilizes contactless technology to provide exceptional reliability and consistent accuracy. Unlike conventional sensors that depend on direct contact with the media and can deteriorate over time, SAW technology is more resilient to faults, which helps reduce maintenance needs and the frequency of calibrations.
Hygienic Design for Pharmaceutical Applications
The FLOWave flowmeter's design effectively eliminates the risk of contamination associated with traditional sensors, which can harbor bacteria. Its straight-through measuring tube prevents the formation of dead zones where particles and microorganisms might accumulate. Furthermore, the flowmeter is made from robust 316L stainless steel and is compatible with CIP/SIP processes, ensuring durability and resistance to corrosion.
The compact and lightweight nature of the FLOWave flowmeter facilitates easy installation without the need for lifting equipment, making maintenance simpler. Additionally, it supports modern digital communication protocols, allowing for seamless integration into existing systems.
Compliance with Pharmaceutical Standards
The FLOWave flowmeter is designed to comply with the highest standards in the pharmaceutical industry, including an FDA certificate of conformity and ASME BPE compliance. Its hygienic design, reliability, and durability make it a dependable choice for pharmaceutical applications.
Alongside the FLOWave flowmeter, Bürkert provides a comprehensive range of components for WFI distribution systems, such as diaphragm valves, point-of-use (POU) valves, control valves, and POU batching systems.
With its accurate flow measurement, ability to prevent biofilm formation, and top-tier hygienic design, Bürkert’s FLOWave flowmeter is the perfect solution for achieving optimal performance in Water for Injection systems.
