Accurate Gas Flow Measurement Made Easy With Precession Vortex Flowmeter

Overview of vortex flowmeter

The vortex gas mass flowmeter is an instrument used to measure gas flow, mainly based on the principle of vortex generation. Its working principle is as follows:

Basic principle: When a fluid (gas) flows through a specific pipe, vortices will be generated in the pipe due to changes in flow velocity. The frequency of these vortices is proportional to the flow velocity of the fluid.

Measurement method: The vortex gas flowmeter usually uses a small vortex generator (such as a small obstacle) to induce vortices. When the gas flows through this obstacle, vortices will be generated downstream. The sensor inside the flowmeter monitors the frequency of these vortices.

Calculate flow: By measuring the frequency of the vortex, the flowmeter can calculate the flow velocity of the gas, and combined with the density of the gas, the mass flow rate of the gas can be calculated.

Advantages: The vortex gas flowmeter has the advantages of simple structure, no moving parts, high reliability, and low maintenance cost. At the same time, it can maintain good measurement accuracy under high temperature and high pressure conditions.

Application field: This flowmeter is widely used in gas flow measurement in industries such as petroleum, chemical, electric power, and environmental protection.

The vortex gas flowmeter has many advantages, which makes it widely used in gas flow measurement. Here are some of the main advantages:

1. Simple structure
No moving parts: The structure of the vortex flowmeter is relatively simple. Since there are no moving parts, this reduces the possibility of wear and failure, thereby improving the reliability and durability of the instrument.

2. Low maintenance cost
Reduced maintenance requirements: Due to its characteristics of no moving parts, the maintenance frequency of the flowmeter is reduced, thus saving maintenance costs and time.

3. High measurement accuracy
Precise measurement: The vortex flowmeter can provide high-precision measurement over a wide flow range, usually with an error of less than ±1%. Suitable for precise control and monitoring.

4. Wide applicability
Suitable for a variety of gases: It can measure a variety of gases, including natural gas, air, nitrogen, hydrogen, etc., and has good adaptability.

5. High temperature and high pressure resistance
Good environmental adaptability: The vortex gas flowmeter can operate normally in a high temperature and high pressure working environment, suitable for various industrial applications.
6. Good linearity
Good flow characteristics: The relationship between the flow rate and the vortex frequency of the vortex flowmeter is relatively linear, which is convenient for flow calculation and adjustment.
7. Fast response speed
Real-time monitoring: The response speed to flow changes is fast, and the changes in gas flow can be monitored in real time, which is suitable for dynamic working conditions.
8. Not affected by the physical properties of the fluid
Strong adaptability: The vortex flowmeter has strong adaptability to the physical properties of the fluid (such as temperature, pressure, etc.), and can maintain stable measurement performance under different operating conditions.
9. Miniaturized design
Small footprint: Many vortex flowmeters adopt a compact design and occupy less space, which is suitable for use in space-constrained environments.
10. Cost-effectiveness
High cost-effectiveness: In many applications, the vortex flowmeter provides a relatively reasonable price and efficient performance, making it a cost-effective choice.
Due to these advantages, the vortex gas flowmeter has been widely used in many industries, such as petroleum, chemical, pharmaceutical, environmental protection and other fields
