Many of the World's leading brewing companies now understand the benefits of producing a growth profile of the biomass over the entire fermentation period from start to finish.  The Yeast Monitor (Model 7720) using "Flush" electrode probes are designed and optimised for this operation.  The data from the Yeast Monitor can be used to determine:

• The initial concentration in the fermentor after pitching
• The state of cell growth; this can have an adverse effect on the quality of the final product.  High rates of cell growth can also result in foaming and loss of product
• A target peak cell concentration; this value might be used to iniate cooling or a transfer over to other vessels
• The progress of the flocculation of yeast after chilling

The probe can be installed either directly into the side wall of the  cylindraconical vessel above the cone or in a pumped pipe loop that circulates the vessels contents.  The output of the vessel will relate to the volume of biomass present around the probe and can be calibrated to any desirable units of mesurement, but commonly in cells/ml.  The signal is then fed into a suitable data logging system and data similar to the chart shown will be available for every fermentation.
