Brewery plants are referred to beer making machine. It is used to produce beer. All styles of beer can be produced, which ranges from ales to lagers. Each brew operation is performed in a separate vessel. The machine contains parts such as, pressure gauges, sampling valves, level-gauge, thermo-wells and fermenter. Fermenters, serving tanks and bright beer tanks may have manway doors either on the top or on the side of the tank. Pressure gauges are attached to a diaphragm shell, which passes the pressure to the gauge's bi-metal sensor. The diaphragm is laser-welded to the fitting to avoid direct contact with the gauge. A 6″ clamped stainless steel thermo well is used to avoid direct contact of a thermometer or sensor with the beer. This brewery plant made up to 25.000 hl of beer per year.
