1. Working principle
The specially designed vortex generator makes the fluid produce rotational motion, forming a stable vortex precession phenomenon, and the sensor detects the vortex frequency to calculate the flow rate.
2. Core function
Gas flow measurement: particularly suitable for accurate metering of gas media such as natural gas, compressed air, and coal gas, with a measurement accuracy of up to ±1.0%.
Steam metering: can be used for flow monitoring of saturated steam and superheated steam.
3. Technical features
Integrated structure: the sensor and signal processor are integrated for easy installation and maintenance.
Wide range ratio: usually up to 10:1~15:1, adapting to a larger flow range.
Strong anti-interference ability: insensitive to pipeline vibration and flow field changes.
4. Industrial application advantages
No need for front and rear straight pipe sections (generally requiring 3D front and 1D rear), saving installation space
No mechanical moving parts, high reliability and long service life
Support temperature and pressure compensation, can directly output standard flow
5. Typical application scenarios
Urban gas transmission and distribution metering
Industrial boiler steam monitoring
Compressed air system energy consumption management
