Application of Electromagnetic Flowmeters in Chemical Scenarios

 Core Application Scenarios

• Corrosive Medium Measurement: Capable of measuring acid-base solutions (e.g., sulfuric acid, sodium hydroxide), salt solutions, chemical solvents (e.g., methanol, ethanol), etc. The sensor lining is made of corrosion-resistant materials such as PTFE and rubber, and the electrodes adopt special materials like Hastelloy and titanium alloy.

• Conductive Liquid Metering: Suitable for various conductive liquids (conductivity ≥5μS/cm) in chemical production, such as chemical slurries, sewage, and reactor discharges, unaffected by medium viscosity, density, or temperature.

• Explosion-Proof and Hazardous Environments: Explosion-proof electromagnetic flowmeters (with certifications like Ex ia IIC T6) can be used in chemical explosive hazard areas (e.g., paint factories, chemical plant areas) to ensure measurement safety.

• Continuous Process Monitoring: Real-time flow monitoring in chemical pipelines facilitates production process control (e.g., batching ratio, feeding speed), and data can be connected to DCS systems for automated management.

 Exclusive Advantages in Chemical Scenarios

• No throttling components, avoiding blockage (suitable for chemical slurries and media containing a small amount of impurities);

• Wide measurement range (flow velocity 0.1-10m/s), adapting to different flow requirements in chemical production;

• High temperature and pressure resistance (some models can withstand ≤180℃ and ≤4.0MPa), meeting chemical reaction conditions.

 Precautions

• Ensure the medium conductivity meets the standard (conductivity below 5μS/cm may easily lead to inaccurate measurement);

• Avoid strong electromagnetic interference during installation (keep away from frequency converters and motors) and ensure the front and rear straight pipe sections meet requirements (5D before and 3D after);

• Regularly inspect lining wear (long-term erosion by corrosive media may cause leakage).
