| Abstract: | In this paper,the characteristic curve of turbine flow sensor and the method to calculate indication error are analyzed.The accumulated flow is used for calculating error and this method is used to calibrate the sub-meter coefficient.Test experiment is done on the standard calibration device and test result is given.Test result has proved that this method not only makes it possible to measure small flow and enlarge the flow range,but also the precision and reliability of flowmeter can be improved. |
