Sanitary Electromagnetic Flowmeter With DN10 To DN200 Quick-Install Flange
Based on Faraday's law of electromagnetic induction: when a conductive medium (such as milk, medicine liquid, or fruit juice) passes through a magnetic field, the electrodes induce an electromotive force proportional to the flow velocity, which is processed by the converter into a standard signal (4-20mA/RS485).
The sanitary electromagnetic flowmeter is a high-precision flow measurement instrument specially designed for industries with extremely high hygiene standards, such as food, beverages, and cosmetics.
| Structural components | Sanitary-optimized design | Core function |
|---|---|---|
| Measurement tube and flow channel | Full flow without diameter reduction, smooth inner wall (Ra ≤ 0.8 μm), no dead zones such as bolts / welds | Avoid medium residue and reduce the risk of bacterial growth |
| Lining material | Food-grade PFA/PTFE (compliant with FDA 21 CFR Part 177), sanitary rubber | Strong chemical inertness, does not react with the medium, easy to clean |
| Electrode assembly | Embedded flush electrode (seamlessly attached to the inner wall of the flow channel), made of 316L stainless steel / Hastelloy C-276 | No protruding structures, avoids medium adhesion, meets sanitary contact requirements |
| Connection method | Quick-install flange (DIN 11851/ISO 2852), clamp connection | Quick disassembly, convenient for online cleaning (CIP) / online sterilization (SIP) |
| Shell and seal | Stainless steel 316L shell, IP67/IP68 protection, food-grade fluororubber seal | Prevent contamination and water ingress, suitable for cleanroom environments |
