Biogas Natural Gas Flow Meter Sensor Vortex Flow Meter 4-20mA RS485

The vortex gas flowmeter is a gas flow measurement instrument based on the principle of fluid dynamics. It mainly uses the vortex phenomenon generated when the gas flows in the pipeline to measure the flow rate. Its working principle can be summarized as the following steps:

1. **Fluid enters the flowmeter**:
The gas fluid enters the vortex gas flowmeter from the pipeline, and the fluid usually flows into the flowmeter measuring pipe section under a certain pressure.

2. **Fluid disturbance and vortex formation**:
When the gas flows through the flowmeter's disturbing fluid (such as a spoiler or a vortex generator), the fluid flow is strongly changed. Due to the unevenness of the flow rate, the fluid produces a rotating flow and forms periodic vortices. These vortices are caused by the gas flow rate.

3. **Generation of vortex frequency**:
The formation of vortices is periodic, and the vortex will break away from the rear of the disturbing fluid at a specific frequency. This frequency is proportional to the gas flow rate. In other words, the larger the gas flow rate, the higher the frequency of vortex generation.

4. **Frequency signal measurement**:
The vortex gas flowmeter is equipped with sensors (usually pressure sensors or vortex street sensors) to detect the frequency of the vortex formed during the flow of the fluid. These sensors convert the frequency of the vortex into an electrical signal.

5. **Flow calculation**:
By measuring the vortex frequency, the vortex frequency can be correlated with the actual gas flow rate according to the calibration curve of the flowmeter. The flowmeter will output the corresponding flow value according to the frequency of the vortex.

Main features:
- **No moving parts**: The vortex gas flowmeter has no moving parts, which reduces the need for wear and maintenance.
- **Strong adaptability**: It is suitable for measuring fluids such as dry gas, steam, air, etc., especially in high flow rate or low flow environment.
- **High stability**: The flowmeter is not very sensitive to changes in gas density and pressure, so it has high stability and accuracy.
- **High accuracy**: It can provide relatively accurate flow measurement, especially for medium to large flow ranges.

Typical applications:
Swirl gas flowmeters are widely used in the fields of petroleum, chemical industry, natural gas, air conditioning systems, environmental monitoring, etc., especially in situations where gas flow needs to be monitored and the fluid state does not change much.

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.
