The rotary vortex flowmeter is a highly advanced device that combines the functions of flow, temperature, and pressure measurement. It is capable of automatically compensating for temperature, pressure, and gas compressibility factors, making it ideal for accurate gas measurement in industries such as petroleum, chemical, power generation, and metallurgy.
This flowmeter operates based on the principle of swirling vortex formation. The flow sensor is designed to resemble a venturi tube, with spiral guide vanes placed at the inlet. As the fluid enters the sensor, these vanes induce a strong swirling motion. Once the fluid reaches the diffuser section, the vortex undergoes recirculation, leading to the formation of a precession phenomenon. The precession frequency is directly proportional to the flow rate and remains unaffected by the fluid’s physical properties or density. A detection element captures this secondary rotation frequency, ensuring excellent linearity across a wide range of flow rates. The signal is then amplified, filtered, and converted into a pulse signal proportional to the flow rate. This signal is processed by a microprocessor along with temperature and pressure data, and the results—such as instantaneous flow, total flow, and environmental parameters—are displayed on an LCD screen.
Key features of the rotary vortex flowmeter include:
1. No moving parts, which reduces wear and tear, ensures long service life, and requires minimal maintenance.
2. Equipped with a 16-bit microcontroller, offering high integration, compact design, and strong performance.
3. Intelligent design integrates the flow probe, microprocessor, pressure, and temperature sensors into a single unit, enabling real-time compensation for compressibility and other factors.
4. Dual detection technology enhances signal strength while minimizing interference from pipeline vibrations.
5. Advanced seismic technology suppresses noise caused by vibration and pressure fluctuations.
6. A Chinese character dot matrix display provides clear and detailed readings, including working and standard state flow values, total volume, pressure, and temperature.
7. EEPROM memory allows for easy parameter setting and permanent storage, with the ability to retain up to one year of historical data.
8. The converter supports multiple output signals, including frequency pulses, 4–20 mA analog signals, and RS485 communication, allowing connection to computers over long distances.
9. Multiple alarm outputs for different physical parameters can be customized by users.
10. The flow meter head can rotate 360 degrees, making installation flexible and user-friendly.
11. Compatible with FM data collectors, enabling remote transmission of pressure and temperature data via the internet or telephone networks.
12. Low power consumption allows operation using either internal batteries or external power sources.

Editor: (Hardware Business Network Information Center) http://news.chinawj.com.cn Buffer ring is a common Machine element, which is used to reduce the vibration and noise generated during the operation of the machine. Buffer rings are mainly divided into two types: rubber buffer rings and spring buffer rings. Rubber buffer rings are suitable for low-frequency vibration and impact, while spring buffer rings are suitable for high-frequency vibration and impact. Buffer ring is an important Machine element, which is widely used in automobile, machinery, electronics and other fields.
