Optimizing Alkaline Water Electrolysis with Ultrasonic Flow Meters

Alkaline water electrolysis is a proven method for producing clean hydrogen, which is essential for sustainable energy solutions. For optimum efficiency and safety in this process, accurate monitoring of the flow rate and concentration of the KOH electrolyte (potassium hydroxide) is essential. Ultrasonic flow meters, such as the ALSONIC Plastic, offer a reliable and precise solution for this.

Why Monitoring Electrolyte Flow Matters 

In alkaline water electrolysis, water in combination with KOH is used as an electrolyte to support hydrogen production. The flow rate and the concentration of the KOH electrolyte have a direct effect on the efficiency of the process and therefore on the profitability of the overall system. 

Advantages of Ultrasonic Flow Meters 

Ultrasonic flowmeters are an excellent choice for measuring and monitoring electrolyte flows due to their non-invasive nature and high accuracy. These devices use ultrasonic waves to measure volume flow and can also determine KOH concentration by analyzing the liquid’s acoustic properties, making them ideal for comprehensive process monitoring. 

Non-Invasive Operation: Full non-invasive measurement; no sensor elements are in direct contact with the KOH solution. This prevents contamination, corrosion, and maintenance issues. 

High Precision: By providing accurate flow rate and concentration measurements, operators can fine-tune the process to maintain optimal conditions for hydrogen production. 

Real-Time Data: Continuous monitoring allows for instant adjustments, preventing inefficiencies and ensuring process stability. 

ALSONIC Plastic: Ideal Solution for Alkaline Water Electrolysis 

The ALSONIC plastic ultrasonic flow meter is perfect for challenging chemical applications, including alkaline water electrolysis. The sealless PPS plastic version is highly resistant to aqueous KOH solutions. This device combines volume flow measurement with KOH concentration determination, delivering all essential data for efficient process monitoring in one unit.
