Yokogawa CA Series Magnetic Flowmeters

Selection Notes

• Confirm that the process fluid has sufficient electrical conductivity for electromagnetic flow measurement.
• Verify the required pipe diameter and flow range for the installation.
• Check whether the fluid contains slurry, particles or adhesive substances.
• Select the required communication protocol, such as HART or pulse output.
• In addition, ensure the process pressure and temperature meet the instrument specifications.

Why Choose Yokogawa CA Series Magnetic Flowmeters

• Designed for Difficult Process Fluids
The CA Series is specifically designed for fluids that are difficult to measure with conventional magnetic flowmeters, including slurry fluids and adhesive liquids.

• Non-Wetted Electrode Technology
Electrodes are installed outside the ceramic measuring tube. Therefore, they do not contact the process fluid. This design prevents electrical noise caused by slurry particles or coating on electrodes.

• Ceramic Measuring Tube for Durability
The flowmeter uses a high-purity alumina ceramic tube, which provides excellent resistance to abrasion and corrosion in harsh industrial processes.

• Measurement of Ultra-Low Conductivity Fluids
Capacitive electrode technology allows the CA series to measure fluids with conductivity as low as 0.01 µS/cm, which is difficult for standard magnetic flowmeters.

• Total Insight Diagnostic Platform
The transmitter includes enhanced diagnostics, verification functions and a clear dot-matrix display. As a result, operators can easily check instrument status and improve maintenance efficiency.

FAQ

Q: What types of fluids can the CA Series measure?
A: The CA Series can measure difficult fluids such as slurry liquids, adhesive fluids and ultra-low-conductivity media.

Q: Why does the CA Series use non-wetted electrodes?
A: The electrodes are located outside the ceramic measuring tube. This prevents contamination or coating from affecting the measurement signal.

Q: What industries commonly use CA Series magnetic flowmeters?
A: They are widely used in chemical processing, pulp and paper production, wastewater treatment and food processing industries.

Q: What is the advantage of ceramic measuring tubes?
A: Ceramic tubes offer excellent resistance to abrasion and corrosion, making them ideal for slurry or aggressive fluids.
