A method was developed for checking weigh tank sampling accuracy that was better than comparing samples from different locations in tanks. Long, narrow, deep weigh tanks with a steep pitch in the bottom yielded the most accurate samples. Cube-shaped tanks with a hopper at one corner, and round tanks gave excellent results. High fat milk was more difficult to mix than lower fat milk. Sampling location influenced gain or loss in fat.
