Spiral Vortex Flowmeter
This product is a velocity-type flowmeter designed based on the principle of fluid forced precession oscillation. It achieves flow measurement by detecting the vortex precession frequency and is suitable for gas media such as natural gas, liquefied petroleum gas, and air. With features including self-rectification and strong anti-interference capability, it is widely used in trade metering and process control in urban gas supply, petrochemical industries, and other fields.
Key Features of The Spiral Vortex Flowmeter
🎯 High-Precision Measurement
Utilizing dual detection technology and intelligent anti-vibration technology, this flowmeter effectively enhances signal strength while suppressing interference from vibrations and pressure fluctuations, ensuring high measurement accuracy for reliable performance.
🛡️ Superior Anti-Interference Performance
Capable of measuring gas containing small amounts of impurities, the flowmeter demonstrates strong resistance to interference, maintaining stable operation even in challenging conditions with excellent reliability and consistent measurement results.
💻 Intelligent Integrated Design
Featuring a 16-bit computer chip, the device integrates flow probe, microprocessor, pressure sensor, and temperature sensor, enabling direct measurement of fluid flow, pressure, and temperature with automatic real-time tracking compensation and compression factor correction.
⚡ Energy-Efficient Operation
With minimal pressure loss (≤0.02MPa), the flowmeter delivers significant energy-saving benefits, reducing operational costs while maintaining optimal performance levels throughout extended operation periods for maximum efficiency and sustainability.
🔧 Robust Construction & Stability
All-metal construction withstands temperatures from -40°C to +120°C, adapting to harsh working conditions. The meter coefficient remains stable long-term without requiring frequent calibration, ensuring consistent accuracy over extended service life.
⏱️ Maintenance-Free Longevity
With no mechanical moving parts and corrosion-resistant design, the flowmeter offers extended service life and requires no special maintenance during long-term operation, minimizing downtime and reducing total cost of ownership.
🔌 Flexible Communication Options
Standard 4-20mA current signal output with optional RS-485 (Modbus-RTU protocol) and HART protocol support enables seamless integration with PLC, DCS, SCADA, and other industrial control systems for comprehensive process automation.
