Brief introduction: 1. Low frequency rectangular binary-wave excitation is adopted, with strong anti-interference performance. 2. Simple structure, solid and high stability. 3. Diameter range: DN20 -- DN200. 4. Accuracy level: 1.0%. 5, working temperature: 25 ℃ ~ + 100 ℃ 6. Used in acid and alkali corrosion fluids: cement slurry, ore slurry, mud, pulp and other two-phase liquid: water supply and drainage system. 7. Protection level: IP65 (water-proof) 8. Working pressure: 1.0 ~ 6.0mpa. 9. Intelligent data display is optional to realize instantaneous display, recording, integration and adjustment of flow. 10. Strong interchangeability of the converter, flow change does not need to re-real flow calibration, the method is simple.
