Abstract
An apparatus for detecting change in the foam forming characteristic of an input stream of an aqueous solution which continuously samples the input stream by taking a series of discrete, independent measurements. A sample of the input stream is collected, analyzed, then discarded. The collect-analyze-discard cycle is repeated. The apparatus relies on an acoustic sensor to measure foam height within a column. This allows the column containing the foam to be fabricated from any material, including durable plastics. A sample of the input stream is introduced into the apparatus. The sample is then aerated by a aeration stone to produce foam. The height of the column of foam produced is then measured using the acoustic sensor. The sample is then discarded and the process repeated. The height of the foam column is correlated with the concentration of foam forming chemical.
