When choosing a vortex flow meter, you can refer to the following clear, point-by-point and summarized steps, combined with the relevant numbers and information in the article:

 

1. Determine the measuring medium and conditions

 

Medium type: The vortex flow meter is suitable for measuring the flow of various liquids, gases and steam. Select the appropriate vortex flowmeter model according to the specific medium.

 

Medium flow rate: The full flow rate of the vortex flowmeter can be selected within the range of 0.5-12m/s for the measuring medium flow rate. Make sure that the selected vortex flowmeter can meet the actual flow rate requirements.

 

Temperature range: The applicable temperature range of the vortex flowmeter is usually -40℃~+200℃ (or different according to the specific model). Make sure that the selected vortex flowmeter can work normally within the temperature range of the measuring medium.

 

Pressure range: The applicable pressure range of the vortex flowmeter is usually 0-16MPa (or different according to the specific model). Select the appropriate vortex flowmeter according to the pressure conditions in the pipeline.

 

2. Select the type of vortex flowmeter

General vortex flowmeter: suitable for the measurement of general liquids, gases and steam.

High temperature vortex flowmeter: suitable for high temperature media, such as steam, etc.

High pressure vortex flowmeter: suitable for flow measurement in high pressure pipelines.

Special media vortex flowmeter: such as corrosive media, viscous media, etc., need to choose a vortex flowmeter with special materials or structures.

 

3. Consider accuracy and functional requirements

Accuracy level: Select the instrument accuracy level according to the measurement requirements and the occasion of use. For example, for occasions used for trade settlement, product handover and energy metering, a vortex flowmeter with a higher accuracy level should be selected, such as 1.0 level, 0.5 level, etc.

Functional requirements: Consider whether remote monitoring, data transmission and other functions are required, and select a vortex flowmeter with corresponding functions.

 

4. Pipeline size and connection method

Pipeline size: Select the appropriate vortex flowmeter caliber according to the actual pipeline size. Generally speaking, the caliber of the vortex flowmeter should match or be slightly smaller than the pipeline caliber.

Connection method: The vortex flowmeter provides a variety of different connection methods, such as flange connection, threaded connection, etc. Select the appropriate connection method according to the actual situation on site.

 

5. Signal output mode

Analog signal: such as 4-20mA, 0-5V, 0-10V, etc.

Digital signal: such as RS485, HART, etc.

Choose the appropriate signal output mode according to user requirements and compatibility of instrument system.

 

6. Power supply mode

Vortex flowmeter generally requires external power supply, usually the working voltage is DC 24V or AC 220V. Select according to site conditions and requirements.
