Precession Vortex Flowmeter High Flow Range And Accuracy Level For Gas Measurement

The technical parameters of vortex gas flowmeters can vary according to different brands and models, but generally speaking, the technical parameters of vortex gas flowmeters include the following important indicators:

1. **Flow range** (flow range)

- **Measurement range**: Flowmeters usually have a wide measurement range, generally ranging from a few cubic meters per hour (m³/h) to several thousand cubic meters per hour (m³/h). The specific range depends on the model and design of the flowmeter.

- **Minimum flow (lower flow limit)**: The minimum flow value that the flowmeter can accurately measure is usually marked.

- **Maximum flow**: The maximum flow value exceeding this value may affect the accuracy of the flowmeter or cause damage.

2. **Accuracy level**

- The accuracy of vortex gas flowmeters is generally **±1%~±2%** (percentage of the range value), and high-end products can reach **±0.5%** or higher.

- Accuracy is usually related to the flow range, stability of the medium, properties of the fluid, etc.

3. **Working medium**
- **Gas type**: Swirl gas flowmeters are suitable for measuring a variety of gas flows, such as natural gas, compressed air, nitrogen, oxygen, steam, fuel gas, etc.
- **Gas density and composition**: Flowmeters usually require the measurement of gas density and composition, and some high-precision models can automatically compensate for changes in gas density.

4. **Working pressure**
- The working pressure range of swirl gas flowmeters is usually **0.1 MPa ~ 10 MPa** or higher, depending on the specifications of the flowmeter. Some high-pressure versions can be used for applications under higher pressures.

5. **Working temperature**
- **Normal working temperature**: Generally between **-40°C ~ 120°C**.
- **High or low temperature type**: Some special models support higher or lower working temperature ranges, suitable for industrial high-temperature and low-temperature gas flow measurement.

6. **Material and corrosion resistance**
- The main material of the flowmeter is usually **stainless steel** (such as 304, 316), and corrosion-resistant coating or special alloy materials can be selected according to needs, which is suitable for measuring corrosive gases.
- Some models also provide **explosion-proof** certification to adapt to the measurement environment of hazardous gases.

7. **Output signal**
- **Pulse signal output**: The vortex gas flowmeter usually outputs flow data through a pulse signal, and the pulse frequency is proportional to the flow rate.
- **Analog signal output**: Some flowmeters provide analog output (such as 4-20 mA, 0-10V, etc.) to connect with the flow control system or data acquisition system.
- **Digital signal output**: Some models support digital communication protocols such as **Modbus, HART**, etc., which is convenient for remote monitoring and data acquisition.

8. **Installation method**
- Flowmeters usually have two designs: **pipe installation type** and **insertion type**, which can be selected according to the size of the pipeline and the application scenario.
- The installation location of the device will also affect the measurement accuracy, usually requiring smooth fluid flow and sufficient straight pipe length.

9. **Overload capacity**
- Most flow meters have a certain overload capacity, such as **1.5 to 2 times the range**, to cope with short-term flow fluctuations or shocks.

10. **Response time**
- The response time is generally **0.5 seconds to 3 seconds**, depending on the design of the flow meter and the characteristics of the fluid. A faster response time helps to monitor gas flow changes in real time.

11. **Display and data acquisition**
- Some swirl gas flow meters are equipped with **local display** (LCD or LED) to display flow values ​​in real time.
- Optional **temperature and pressure compensation** functions can further improve measurement accuracy.

12. **Protection level**
- The protection level is usually **IP65, IP67**, which is dustproof and waterproof, and can be used outdoors or in harsh environments.

13. **Power Requirements**
- The power requirements for vortex gas flowmeters are usually **DC 24V** or **AC 220V**, but some models may support a wider power voltage range.

14. **Explosion-proof Certification**
- When used in an explosive gas environment, the flowmeter may require **Ex explosion-proof certification** to ensure the safe operation of the device in hazardous environments.
Summary:
The specific technical parameters of the vortex gas flowmeter depend on the device model and its design requirements. When selecting a model, you need to consider factors such as the working environment, flow range, gas type, and accuracy requirements.
