Abstract：To reduce the measurement error caused by the non-unidirectional diverter in the water flow standard facility, an unidirectional diverter was manufactured. The principle of the new diverter was analyzed and the flow rate measurement model also was developed based on the principle. The following conclusions were obtained that the measurement results had nothing with pulse trigger position, velocity distribution and diverting time according to the flow measurement model derivation process. The experimental research was carried out by means of the water flow standard facility. Experimental results showed that the new diverter could reduce the errors caused by the non-unidirectional diverter. So the new diverter could be used for the water flow calibration facility to measure water flow rate intead of the non-unidirectional diverter.
