Accuracy : ±0.5%, ensuring the reliability of flow data.

Flow rate range : 0.01–5 m/s, balancing both low-velocity monitoring and high-speed flow scenarios.

Environmental Adaptability : Operating temperature -25℃ to +55℃ (customizable low-temperature version down to -45℃), with humidity ranging from 5% to 90%, making it suitable for harsh industrial environments.

2.  Safety and Stability

Protection Level : IP65-rated, effectively dustproof and waterproof, suitable for humid or dusty environments.

Pressure Level 1.6 MPa, meeting the pressure requirements of conventional industrial pipelines.

Power Supply Compatibility DC 16–30 VDC, with power consumption as low as 3 VA—energy-efficient and compatible with a variety of power systems.

3.  Materials and Structural Design

Measurement tube lining PEEK material combines high-temperature resistance and corrosion resistance, preventing medium residue.

Integrated Structure : Reduce external interference, enhance signal stability, and simultaneously lower maintenance costs.

III. Typical Application Scenarios

1.  Pharmaceuticals and Bioengineering

In vaccine production, reagent formulation, and other critical processes, precise control of minute liquid flow rates is essential. The high accuracy of this flow meter, combined with its hygienic-grade materials—such as clamp-style connections—ensures compliance with GMP standards.

2.  Food and Beverage Industry

Suitable for applications such as filling lines and seasoning addition, its corrosion-resistant electrode paired with food-grade materials ensures the medium remains free from contamination.

3.  Chemical Engineering and Environmental Monitoring

Designed for monitoring the flow of acid-alkali solutions, pure water, or wastewater, it is optimized for low-conductivity media, enhancing the accuracy of data collection.
