YFLJB series standard orifice flowmeters are designed and manufactured strictly in accordance with standard documents GB / T2624 and ISO5167, and have been maturely applied to flow measurement of liquid, gas, steam, and partially mixed flow (gas-solid, gas-liquid, liquid-solid, etc.). The sealing surface of the pressure taking flange adopts the FM surface seal, which makes the throttle piece and the pressure taking flange seal better. At the same time, the installation of the throttle piece has better self-centering, which effectively improves the measurement accuracy and safety of the flow meter. performance.
