Uncertainty Assessment of
Mine Fan Flowrate Measurement |
| |
| Abstract: | In this paper the author puts forward the assessment method of uncertainty in fan's flowrate measurement according to the standard requirements for the test device when fan's flowrate is measured with a conical inlet under the test conditions of fan's aerodynamic performance in a standardized air tunnel. Assessment was conducted through some measurement examples. Thus, this will provide basis for the correct assessment of uncertainty of fan's flowrate measurement and the improvement of the accuracy degree of fan test. |
