3.Structural design
Electromagnetic flow meter:
Lining material: PTFE/F46 (strong corrosion resistance)
Electrode material: 316L/Tantalum (acid and alkali resistant)
Anti-clogging: no obstruction parts, suitable for flocculants containing trace solid particles
Turbine flow meter:
Impeller material: tungsten carbide (wear-resistant)
Bearing: Carbide (long life)
4.Installation and working condition adaptation
Installation method: flange connection (GB/T9119)
Medium temperature: ≤80 ℃(high temperature type can reach≥ 120℃)
Pressure level: 1.6MPa (optionally higher)
Explosion-proof requirements: Ex dⅡ BT4 (optional)
5.Selection suggestions
1.High viscosity/corrosive flocculants: Electromagnetic flowmeter (PTFE lining) is preferred.
2.Low viscosity/cleaning solution: optional turbine flowmeter (economical type).
3.Maintenance points:
Clean the electrode/impeller regularly (to prevent flocculant adhesion)
Avoid long-term dry operation (turbine flowmeter requires medium lubrication)
If need a QH curve or corrosion test report for a specific model, please specify the flocculant composition (such as pH value, solid content).
Electromagnetic flowmeter: (Cr27 high chromium alloy lining)
Turbine flowmeter: (low power consumption design)
