Abstract :
A water flow diverter is an essential and error determining component of a liquid flow facility based on a static gravimetric system with flying start and finish. A new diverter was developed in order to reduce the uncertainty, noise and vibration by using a stepping motor to drive the dividing body. The reasons of the diverter timing error and test methods were studied. It is shown by the test results that the uncertainty of the diverter is better than 0.007%.
