Measurement accuracy: liquid ± 0.5%, gas / steam ± 1.0%;

　　Low requirements for straight pipe section: front straight pipe section (0-3) d, rear straight pipe section (0-3) d;

　　Dirt resistant, not easy to block: self purging structure design, no stagnant dead zone;

　　It can be used to measure medium under complex working conditions: dirty medium containing impurities and easy to crystallize, high temperature and high pressure medium, gas-liquid two-phase medium, multiphase water flow, vibration water flow, electromagnetic interference medium, various mixed gases, etc.
