| Abstract: | The equal-graded accuracy dissemination system for flow value of quantity using the equalgraded flowmeter as a standard to calibrate the other flowmeters is presented in the paper. The factors that influence the dissemination accuracy in such system are analyzed and the general features of the system are evaluated with the method of experimental study. The experimental results show that if the instrument features have good repeatability then the actual accuracy of the flow standard facilities with standard meter method using them will approach or reach the accuracy of the higher graded standards. |
