TEST EQUIPMENT AND ITS APPLICATION FOR MEASURING VACUUM IN THE SHORT MILK TUBE

Summary: Both ASAE and ISO standards cite recommendations for the minimum requirements of recording equipment to evaluate vacuum stability in the various parts of the milking machine. Milking-time tests require the use of instruments with response characteristics which are appropriate for the measurement of expected rates of vacuum change. This paper presents the results of a study conducted to determine the characteristics of vacuum fluctuations in the short milk tube during milking and during wet tests with flow simulators.
