Core Technology & Product Systems

Vacuum Potting Technology for Moisture Resistance
Xinya’s proprietary epoxy resin vacuum sealing process encapsulates excitation coils, achieving IP68-grade protection against moisture ingress. This technology eliminates electrical reliability issues in high-humidity industrial environments, validated through deployment in Indonesia wastewater treatment facilities where polymer measuring tubes prevented scaling and corrosion in continuous humid exposure.

Advanced Material Innovation
The company’s non-magnetic loss flowmeter series utilizes two breakthrough material systems:

• Ceramic Measuring Tubes: Constructed from 99% high-purity alumina or 99.5% high-purity zirconia (Mohs hardness 9), operating at temperatures up to 180°C and pressures to 10 MPa while resisting vacuum collapse at 0.095 MPa. Deployed in Brazil metallurgy facilities, ceramic flowmeters withstood extreme abrasion and pressure fluctuations in slurry transport applications.

• FRP/Polymer Composite Tubes: Resin-based non-metallic construction eliminates magnetic field unevenness while handling negative pressure conditions. This design provides corrosion resistance equivalent to traditional rubber-lined meters at superior cost efficiency, proven in Turkey chemical facilities where high-accuracy (±0.2%) ceramic meters enabled precise acid and solvent dosing.

Precision Winding and Electromagnetic Balance
Optimized excitation coil winding maintains 0.2mH inductance tolerance, ensuring stable electromagnetic field generation. Combined with electrode shielding technology, this approach reduces electrical noise and achieves ±0.2% measurement accuracy across the SF electromagnetic flowmeter series.
