From Flow Measurement
Many industries require equipment that meets specific design and construction
criteria to ensure "sanitary" conditions. Here, "sanitary" does not refer to waste
treatment applications but to highly "clean" conditions. The most common usage
of sanitary flowmeters is in industries where bacteria growth and product contamination
are a critical concern, such as in the production of food, dairy, and pharmaceutical
products. Although this is the prime consideration in selecting a sanitarytype
flowmeter, applications in a variety of non-food industries also require sanitary
design flowmeters for reasons other than prevention of bacterial growth or
Design requirements and specifications for sanitary flowmeters originated in
the dairy industry. The handling and packaging of a perishable product such as
fluid milk required components that did not compound the problem of product
spoilage and bacterial growth. Equipment of all types, including flowmeters, had
to be designed to ensure that milk residue did not become trapped or be caught
and left to spoil. These pockets of spoiled product could harbor areas of harmful
bacterial growth and later contaminate fresh product. Flowmeters were designed
to eliminate cracks, crevices, and dead ends where residue could collect or pockets
of bacteria could form. In addition, flowmeters had to...
