The Application of Differential Flowmeter for Large Bore Pipeline Gas Mete ring

The measurement o f blast furnace gas in iron and steel pl ants is a tough subject.Based on the ana lysis of existing problems in applicatio n of traditional segmental orifice in pa st of years the application of concentri c circles orifice and integrated Annubar flowmeter in 2 meters above large bore pipeline gas measurement is presented. A fter a long period operation, the detect ing data are stable, especially the inte grated Annubar flowmeter with backblowin g device successfully resolved the block problem. This makes excellent prospect for gas flow measurement of blast furnac e, coke oven and converter in iron and s teel plants.
