1.Product Overview
Vortex flow meters operate based on the vortex precession principle, wherein fluid passing through a vortex generator forms vortices that are forced to rotate within a venturi tube. Flow measurement is achieved by detecting the vortex precession frequency, which is directly proportional to flow rate. Suitable for gaseous media such as natural gas, liquefied petroleum gas, and air, these meters are widely used in small-to-medium diameter pipelines due to their self-rectifying capability and strong resistance to interference. Applications include natural gas metering, boiler and burner gas metering, and industrial process gas metering.
natural gas metering, boiler and burner gas metering, and industrial process gas metering.
2.Product Advantages
Utilizes dual detection technology and intelligent anti-vibration technology to effectively enhance detection signal strength, suppress interference caused by vibrations and pressure fluctuations, and achieve high measurement accuracy;
Capable of measuring gases containing trace impurities with strong anti-interference capability;
Incorporates a 16-bit computer chip integrating flow probe, microprocessor, pressure, and temperature sensors to directly measure fluid flow rate, pressure, and temperature, with automatic real-time tracking compensation and compression factor correction;
Low pressure drop (≤ 0.02MPa) delivers significant energy savings;
All-metal construction with temperature tolerance from -40°C to 120°C, suitable for harsh environments. Instrument coefficient remains stable long-term without frequent calibration;
No mechanical moving parts, corrosion-resistant, extended service life, and requires no special maintenance during prolonged operation.
Standard 4-20mA current signal output, optional RS485 (Modbus protocol) or HART protocol, enabling seamless integration with industrial control systems such as PLC, DCS, and SCADA.
