Introduction: There is no one-size-fits-all technology, only the most suitable solution. The unique characteristics of flow battery electrolytes (corrosiveness, bubbles, temperature changes)
necessitate careful selection of level monitoring technology. This article compares three mainstream technologies to provide a basis for selection.

Flow Battery Application Compatibility
Capacitive: Best suited for small to medium-sized tanks, high cost-effectiveness, corrosion-resistant versions can directly contact the electrolyte.
Ultrasonic: Suitable for large tanks, but electrolyte vapors may affect measurement accuracy.
Radar: Highest accuracy, almost unaffected by operating conditions, but expensive, suitable for high-standard applications.
Selection Recommendations
Based on a comprehensive consideration of tank size, accuracy requirements, and budget, capacitive sensors offer the best overall cost-effectiveness in most flow battery applications.
