| Abstract: | When the resistent to high temperature positive displacement flowmeter is used to measure the flow of the high temperature medium, it is necessary to have a correction for the measuring result. The article discusses that When the viscosity of measured medium varies with the temperature, the theoretical model of the correction of the measuring result of the flowrneter is set up. At the same time, the concept of the oringinal error and the induced leak of the flowmeter are put forward by the article. |
