進口氣體超聲波流量計產(chǎn)品用途 Product use

采用復(fù)用雙聲道（DN25-DN-80）和復(fù)用六聲道（DN100-DN200）設(shè)計，可以消除渦流和不對稱流影響，復(fù)用聲道增加冗余備份聲道，提高系統(tǒng)的可靠性。廣泛用用于城市燃氣、石油、化工、電力、冶金等行業(yè)氣體的流量計量

The unique design of multiplexed dual channel (DN25-DN-80) and multiplexed six channel (DN100-DN200) can eliminate the impact of eddy current and asymmetric flow. The multiplexed channel adds redundant backup channels and improves system reliability. Widely used for gas flow measurement in urban gas, petroleum, chemical, electric power, metallurgy, and other industries
