Dynamic Foam Analyzer
Analyzing liquid content and drainage of foam
- Data sheet
The LCM Liquid Content Module for the DFA100 measures the moisture of foams with respect to time on different foam height levels. The results are obtained by detecting the foam's conductivity as a proven method. They provide you with knowledge about a foam’s stability and help you optimize products where moisture plays a key role, such as washing foams.

Fast measurement of foam stability
In addition to showing moisture as a direct quality criterion for foam, liquid content measurement also reveals the stability, because the discharge of liquid from the foam lamellae (drainage) is the first sign of decay. Therefore, accurately measuring the liquid content as a function of time is ideal for evaluating foams in the range of long-term stability. Since it is not necessary to wait until the foam height decreases, detecting moisture can save measuring time and significantly increase sample throughput.
DYNAMIC FOAM ANALYZER
Scientific characterization of foam
Foam in everyday products as well as technical applications appears in manifold forms and is often produced on purpose, but can also be undesired. Our DFA100 characterizes almost every aspect of foam, putting a wide range of methods into practice with impressive ease of use.
Accurate moisture analysis at seven height levels
The liquid content is measured simultaneously at up to seven height increments of the foam. This accurate high resolution shows how uniform the foam is and how the homogeneity changes with time. This information is relevant for many foam products, such as food foam, which should have the same consistency everywhere, even after a long time. Liquid content measurement can be carried out simultaneously with foam height detection and foam structure analysis.
Automatic analysis and powerful evaluation
The simple operation of the instrument goes hand in hand with the intuitive user interface of our ADVANCE software. Easy to create automation programs control the measurement run and allow cyclical repetitions. The synchronous display of all time-related data for foam height, bubble structure, and liquid content is particularly convenient.
