The YFLJB series standard orifice flow meter is designed and manufactured in strict accordance with the standard documents GB/T 2624 and ISO 5167, and has been maturely applied to flow measurement including liquid, gas, steam, and partial mixed-phase flows (gas-solid, gas-liquid, liquid-solid, etc.) . The sealing surface of the pressure-taking flange adopts FM surface sealing, which makes the sealing effect of the throttling and pressure-taking flange better, and at the same time makes the installation of the throttling piece have better self-alignment, which effectively improves the measurement accuracy and safety performance of the flow meter.
