The July Technology Evening was kindly sponsored by Endress+Hauser and Natlee Chetty gave an informative and interesting presentation on ‘Flexible Flow Measurement According to the Differential Pressure Principle’.

Natlee gave a résumé of basic principles relevant to the use of differential pressure for measuring flow and provided examples of primary elements used in those applications. The square root relationship between flow and differential pressure was demonstrated, with the simplified version and the much more accurate Bernoulli equation as generally applied in flow computers being highlighted. Special attention was paid to compressible fluids and the physical laws determining their behaviour, as well as the influence of the Reynolds number. While discussing pitot and other cross pipe averaging devices, the dependence of the K factor on the configuration and geometry of the primary element was emphasised and the manner in which it was determined for each type of element was explained.
The branch was pleased to welcome the Endress+Hauser team of (left to right) Vernon Moodley, Natlee Chetty, Minnesh Bugareth and Nelson Reddy.
Use of differential pressure across a primary element remains one of the most commonly applied – and often misapplied – ways of measuring flow, because of its simplicity and relatively low cost. Natlee took a comprehensive look at these aspects in the context of commonly applied types of flow measurement. After a short question and answer session a delicious supper and much networking was enjoyed by all.
