Foam Density Meter Inline

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.

Applications

Some production lines or industrial plants could benefit from the ultrasonic foam density meter:

● Food & Beverage Production for density control in aerated products like ice cream, whipped cream, or mousse mixing tanks and beer/soft drink carbonation lines;

● Pharmaceutical & Biotech Plants for density monitoring in fermentation bioreactors to prevent foam-over and optimize cell growth, and in vaccine/drug suspension aeration processes;

● Wastewater Treatment Plants for foam blanket thickness and density measurement in aeration basins and digesters to manage biological activity and prevent equipment damage;

● Chemical Processing Plants for monitoring foam formation in distillation columns and reactor vessels, allowing for precise, on-demand anti-foam agent injection;

● Pulp and Paper Mills for foam density control in pulp washing stages and flotation de-inking processes to improve fiber recovery and reduce chemical consumption;

● Mining & Mineral Processing for froth density and stability measurement in mineral flotation cells to ensure optimal separation efficiency and ore recovery.
