Analysis of the Causes of Foam Interference During operation,floor scrubbers generate a large amount of
foam from the mixture of detergent and wastewater, posing a significant challenge to liquid level detection:
Limitations of Traditional Sensors
Optical Sensors: Misidentifying foam as liquid
Float-type Sensors: Foam causes float jamming
Electrode-type Sensors: Foam causes misleading signal transmission
Breakthrough of Capacitive Solution
Utilizing patented frequency domain analysis technology, accurate identification is achieved through:
Multi-frequency signal acquisition
Intelligent analysis of medium characteristics
Dynamic threshold adjustment algorithm
