Spiral dual rotor flowmeter

Product Name: Spiral Double Rotor Flow Meter Product Number: HDFF Application Range: Spiral rotor flow meter is the latest product in the field of volumetric flow meters. The measuring part is a pair of spiral rotors with special tooth shapes, used for measuring and controlling liquid flow in pipelines. Features: ■ Precise design and professional craftsmanship, with extremely high precision and repeatability; Double rotor spiral structure design, contactless rotation, uniform displacement, smooth operation, low vibration and noise; No need for straight pipe sections, accuracy is not affected by fluid flow conditions, and it can adapt to a wide range of medium viscosity. Main technical parameters: nominal diameter: DN40~DN300 nominal pressure: 1.6 MPa~6.3 MPa accuracy: 0.1 level, 0.2 level, 0.5 level measurement range: 0.25 m3/h~3000 m3/h viscosity range: 0.3 mPas~2500 mPas ambient temperature: -20 ℃~+55 ℃ medium temperature: -20 ℃~+100 ℃, can reach 150 ℃ relative humidity: 45%~95% output pulse signal: Vp-p ≥ 7V (+12~24VDC power supply three wire system) Vp-p ≥ 6V (+24VDC two-wire system RL=1000 Ω) explosion-proof grade: d Ⅱ B T4
