Study on the dynamic characteristics of gas-liquid mixing phenomenon in pressure pipeline

The dynamic pressure test space is relatively limited and appeared with high temperature at the same time. Therefore, higher requirements are put forward for the tester. At present, It is necessary to lead the high temperature pressure in the pressure pipe system for measurement. In order to avoid the impact of high temperature medium and pipe system resonance on the test results, this paper proposes a gas-liquid mixed pipe system test system, avoided the influence of high temperature medium on the output characteristics of the sensor, and the influence of pipe system resonance on the test results is also reduced.
