In a typical process, a transducer (transmit and receive) is mounted on a stainless steel pipe. Whilst the mechanical aspects of the construction of such systems are quite straightforward there is a very wide range of pipe sizes in a plant that requires monitoring. As an example, a system designed for use in a margarine plant is shown in Figure 21.2. Manufacturers of commercial equipment for ultrasound charaterization of dairy lipids are listed in Table 21.1.

Various sources of lipid have been incorporated into ruminant diets to increase the energy density and provide the large amount of energy needed for slaughter animals to achieve market weight or for dairy cows to produce milk (see Milk and milkproducts). Fats also reduce the dustiness of feeds, increase the feedstuffs abiUty to pellet, and improve feed acceptabiUty. 

Animal and dairy fats can be differentiated from plant lipids on the basis of the FA distribution animal fats generally contain less palmitic acid than stearic acid, while palmitic acid predominates over stearic acid in plant oils.
