Externally mounted continuous measurement of extract in the fermenter
Measurement of apparent extract during fermentation is one of the most important pieces of information in beer production. Sample withdrawal and subsequent laboratory analysis is still the most common method of measurement.
Continuous automatic measurement is currently possible, using e.g. differential pressure measurement of a fixed level and a change in static pressure due to a change in density. However, tappings have to be retrofitted in existing tanks for this type of measurement. This might lead to problems in connection with welding work, erection of scaffolding, approvals by TUEV (Technical Inspection Organisation in Germany) and downtimes. For new installations, the tank design might have to be modified. Delgado) - and brought to market maturity.e. 2).g.
