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

　　It is applied to the measurement of gas, liquid, gas-liquid two-phase, liquid gas, two-way flow, dirty medium and slurry;

　　Range ratio: the conventional range ratio is 10:1. and the appropriate parameters can be increased to 20:1-30:1;

　　Low requirements for straight pipe section: balanced rectification function, usually as small as 0.5d-2d;

　　The repeatability is up to 0.1%, and the service life is 5-10 times longer than the traditional throttling device;

　　Dirt resistant and not easy to block;

　　Support bidirectional measurement
