Abstract
A theoretical model is derived which shows that flow measurement errors of up to 5 per cent can result if turbine flowmeters are subjected to changes in upstream velocity profiles. This theory is then used to show how proper meter design can considerably reduce these errors. Experiments in a 50·8 mm (2 inch) diameter pipe, with water as the working fluid, were made to confirm the model and the suggested design improvements. The test results show good correlation with theory.Keywords
