The concentration of potassium hydroxide is a key process parameter in alkaline electrolysis and has a direct impact on the efficiency of hydrogen production. If the concentration is too low, the efficiency of power conversion decreases; if it is too high, energy demand increases and the lifespan of the electrolysis cells can be shortened. Even the smallest fluctuations can have significant effects on yield and operating costs.
With LiquiSonic® measure the KOH content continuously and with the highest precision, across the entire range, from 0% to saturation. The ultrasonic measurement method provides a stable signal, regardless of the color, turbidity, or conductivity of the liquid. The accuracy of ±0.05 wt% ensures that the process is optimized and resources are used in the best possible way.
Ein weiterer Vorteil: Dank der kontinuierlichen Messung direkt im Prozess entfallen zeitaufwändige Probenahmen und Labormessungen. Das spart nicht nur Zeit, sondern erhöht auch die Prozesssicherheit, da Messwerte in Echtzeit vorliegen. Das robuste, wartungsarme Plug & Play Design gewährleistet eine lange Lebensdauer des Systems und eine schnelle Amortisation der Investition.
Electrolyzers are not all the same – concentrations, temperatures, flow rates, and plant configurations vary from operator to operator. LiquiSonic® is therefore designed to easily cover these individual differences.
Our sensor measures reliably across the entire concentration range from 0% to saturation and remains stable even at high process temperatures of up to 120 °C. This makes it ideal for the typical concentration range of 20–40 wt% KOH at temperatures between 50 and 85 °C, as is typical in alkaline electrolysis.
The installation is straightforward: The LiquiSonic® immersion sensor is installed directly into existing pipelines without major modifications. Via the LiquiSonic® Controller 30 up to four sensors can be operated simultaneously, allowing multiple electrolyzers to be monitored with just one system. Continuous data recording enables seamless documentation and facilitates process optimization.
Even customer-specific requirements – from special installation situations to interface adjustments to extended reporting options – can be implemented. This way, you get a measurement solution that is precisely tailored to your processes.
Gas bubbles are an unavoidable byproduct of electrolysis – and a major challenge for precise measurement technology. Even the smallest bubbles can disturb the sound signal and distort measurements if not properly accounted for. This leads to unnoticed measurement errors in conventional systems that can impair process control.
SensoTech has therefore adapted the sensor design to this challenge. The combination of innovative architecture and intelligent signal processing ensures that gas bubbles are detected, their influence compensated, and the measurement results reliably displayed. Using AI algorithms, the signal changes caused by gas bubbles are analyzed and corrected, so the user receives a clean, reliable measurement result.
Furthermore, the technology goes a step further: It quantifies the amount of gas bubbles and presents them as a reproducible measurement variable. This allows changes in the process, such as unusually high gas production or disturbances in gas separators, to be detected early. This enables quick diagnosis, reduces downtime, and improves plant availability.
With this function, operators have a clear overview of the state of their electrolysis at all times and can react to deviations immediately – a decisive advantage for safe, efficient, and stable hydrogen production.
