Performance Advantages

What Magnetic Measurement Delivers to Your Process

Magnetic flowmeters are trusted in demanding industrial processes because they deliver stable accuracy, minimal maintenance, and reliable performance even in challenging fluid conditions.

Direct Mass Flow Outpu

Measures gas mass flow directly using thermal dispersion, eliminating the need for complex, error-prone pressure and temperature compensation calculations.

High-Accuracy Stability

Utilizes dual-platinum resistance temperature sensors to maintain precise measurements in fluctuating gas flow environments with excellent signal stability and repeatability.

Wide Velocity Range

Monitors flow velocities from 0.1Nm/s to 120Nm/s with high sensitivity, providing consistent accuracy for both low-flow leakage and peak demand.

Digital Signal Clarity

Adopts high-integration digital circuit design to ensure measurement accuracy, minimize electronic drift, and provide a stable, repeatable output signal.

No External Compensation

Eliminates the costs of purchasing, installing, and maintaining additional pressure or temperature sensors, simplifying your hardware and reducing investment costs.

Maintenance-Free Longevity

With no moving parts to degrade, this meter significantly lowers service frequency, ensuring continuous uptime & reduced maintenance expenditure.

Resilience in High-Heat

Engineered to operate reliably in process temperatures up to 350°C, providing a robust solution for high-heat steam and gas lines.

Instant Response Time

High-speed thermal sensing technology reacts to velocity changes in under one second, enabling precise control in dynamic, fast-cycling process loops.
