Accurate flow measurement plays a critical role in process control, energy management, and production efficiency in modern industries.
In sectors such as chemical processing, mining, metallurgy, and environmental treatment, fluids often contain corrosive chemicals, abrasive particles, or high solid content.
Under such harsh conditions, traditional rubber or PTFE-lined electromagnetic flow meters may suffer from:
Liner wear/Reduced measurement stability/Frequent maintenance or replacement
To address these challenges, ceramic electromagnetic flow meters have become a reliable solution for measuring aggressive and abrasive fluids.
As a professional flow meter manufacturer in China, Kaifeng Xinya Instrument Co., Ltd. has accumulated extensive experience in the development and production of ceramic magmeters for industrial applications.
Key Advantages of Ceramic Electromagnetic Flow Meters
High-Purity Ceramic Measuring Tube
Xinya ceramic electromagnetic flow meters are available with two advanced ceramic materials:
99% Alumina (Al₂O₃)
Excellent chemical resistance and suitable for most corrosive liquids.
99.5% Zirconia (ZrO₂)
Higher toughness and better impact resistance for abrasive slurry applications.
The ceramic tube is manufactured using isostatic pressing and high-temperature sintering, forming a dense and durable structure with:
High mechanical strength/Excellent corrosion resistance/Outstanding wear resistance/Smooth internal surface to reduce adhesion and clogging
Available size range: DN3 – DN200.
Replaceable Electrode Design
The flow meter adopts a replaceable electrode structure instead of an integrated sintered electrode.
Key advantages include:Customizable electrode materials/Reliable sealing structure//Stable long-term operation.
This design improves adaptability to various industrial media and operating conditions.
Traceable Flow Calibration System
To ensure accurate flow measurement, Xinya has developed an in-house high-precision liquid flow calibration system.
The system adopts two calibration methods:
Gravimetric Method
High-precision weighing system used as the primary calibration reference.
Master Meter Method
A 0.2-class electromagnetic flow meter is used as the reference meter for fast and stable flow comparison.
The calibration system is equipped with:
Pressure stabilizing tank/Degassing device/Variable-frequency pump system
These components maintain stable flow conditions and eliminate disturbances caused by air bubbles or pressure fluctuations.
caused by air bubbles or pressure fluctuations. Combined with an automated computer control system, the device supports:
Multi-point automatic calibration/Real-time data acquisition/Automatic calibration certificate generation
All calibration procedures comply with JJG national metrological verification standards, ensuring traceable and reliable measurement performance.

Selection Considerations
When selecting a ceramic electromagnetic flow meter, the following factors should be evaluated:
1 Fluid properties: Corrosiveness, abrasiveness, viscosity, and solid content.
2 Electrical conductivity: Electromagnetic flow meters require conductive liquids, typically ≥5 μS/cm.
3 Solid particle content: Important for slurry or high solid content fluids.
4 Temperature and pressure conditions: Confirm that the medium temperature and pipeline pressure are within the equipment design range.
5 Pipe size and flow range: Select the appropriate diameter to ensure the flowmeter operates within the optimal flow velocity range.
6 Manufacturer capability:Choosing a manufacturer with in-house production and calibration capability ensures better product reliability and technical support.
