Harbin Longjiang Instrument Factory, the production of Roots flowmeter has more than 10 years of history, Roots flowmeter has developed into a more complete series. From the caliber: D_g25.D_g40.D_g50.D_g80.D_g100.D_g150.D_g200.D_g250.D_g300. Nine specifications. From the pressure: 10kgf / cm ~ 2, 16kgf / cm ~ 2, 25kgf / cm ~ 2, 40kgf / cm ~ 2,64kgf / cm ~ From the temperature there are ≤ 90 ℃, ≤ 120 ℃, ≤ 200 ℃, ≤ 350 ℃. From the flowmeter and secondary instrument supporting there are four models. This series of instruments, has been widely used in oil fields, refineries, power plants and other departments, energy conservation work played a
