Application of intelligent vortex gas flowmeter in gas fields and urban natural gas

The main uses of the intelligent vortex flowmeter: It can be widely used in the petroleum, chemical, electric power, metallurgy, urban gas supply and other industries to measure various gas flows. It is currently the preferred product for oil field and urban natural gas transmission and distribution metering and trade metering.

The working principle of the intelligent vortex flowmeter: A set of spiral guide vanes are placed on the inlet side. When the fluid enters the flow sensor, the guide vanes force the fluid to produce a violent vortex flow. When the fluid enters the diffusion section, the vortex flow is affected by the backflow and begins to rotate twice, forming a gyroscopic vortex precession phenomenon. The precession frequency is proportional to the flow rate and is not affected by the physical properties and density of the fluid. The secondary rotation precession frequency of the fluid measured by the detection element can obtain good linearity within a wide flow range. The signal is amplified, filtered, and shaped by the preamplifier to be converted into a pulse signal proportional to the flow rate, and then sent to the microprocessor together with the temperature, pressure and other detection signals for integration processing, and finally the measurement results (instantaneous flow, cumulative flow and temperature, pressure data) are displayed on the LCD screen.

The main features of the intelligent vortex gas flowmeter:

1. Built-in pressure, temperature and flow sensors, with high safety performance, compact structure and beautiful appearance.
2. Display temperature, pressure, instantaneous flow and cumulative flow on site.
3. Adopt new signal processing amplifier and unique filtering technology to effectively eliminate interference signals generated by pressure fluctuations and pipeline vibration, greatly improve the anti-interference ability of the flow meter, and make small flow have excellent stability.
4. The unique time display and real-time data storage function can ensure that internal data will not be lost under any circumstances and can be permanently stored.
5. The whole machine has extremely low power consumption and can be powered by internal batteries for a long time. It is an ideal on-site display instrument without external power supply.
6. The anti-theft function is reliable and has password protection to prevent parameter changes.
7. The head can be rotated 180 degrees at will, which is easy to install.

The application of intelligent vortex gas flowmeter in natural gas flow has been very extensive, and it is the best choice for natural gas flowmeter measurement at present.
