Kaidi KD YELJZ Nozzle Flow Meter High temperature and pressure resistance, impact resistance
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.
