Working Principle
The
inline density meter for foam relies on ultrasonic sensing technology to measure liquid density: it first detects the transmission time of sound waves as they travel from a signal emitter to a receiver through the target liquid. The key to accurate density calculation lies in the inherent correlation between sound wave velocity and liquid density—specifically, sound travels slower in denser liquids and faster in less dense ones. By quantifying this velocity variation, the meter converts the measured transmission time into precise density readings.
