Introduction to Vortex Flow Meters and Its Applications in Chemical and Petrochemical Processes

Vortex flow meter is a device used to measure the flow of various process fluids, including steam, gas, and liquid. It is widely used in chemical and petrochemical processes, where accurate and reliable flow measurement is crucial. In this article, we will discuss the basics of vortex flow meters and their applications in different industries.

PESCO INSTRUMENT & METER CO., LTD, a subsidiary of PETROL STEEL CO., LTD, is a leading manufacturer of vortex flow meters. We design and process flow meters according to user requirements and provide comprehensive solutions for flow measurement.

How Does a Vortex Flow Meter Work?

A vortex flow meter works on the principle of the von Kármán effect, which indicates the formation of vortices when a fluid flows past a bluff body. In a vortex flow meter, a bluff body is placed perpendicular to the fluid flow. The fluid flow creates a series of vortices downstream of the bluff body. The frequency of the vortices is proportional to the fluid velocity, and their amplitude is proportional to the mass flow rate.

The process fluid, usually a gas or liquid, flows through the pipe containing the vortex flow meter. The vortices formed downstream of the bluff body are detected by a sensor located on the other side of the pipe. The frequency of the vortices is converted into an electrical signal, which is proportional to the fluid velocity and mass flow rate.

Applications of Vortex Flow Meters in Chemical and Petrochemical Industries

In the chemical and petrochemical industries, vortex flow meters are used to measure the flow of various process fluids, including flammable gases, corrosive liquids, and high-temperature fluids. Some typical applications of vortex flow meters include:

1. Chemical manufacturing: Vortex flow meters are used to measure the flow of fluids in various chemical processes, such as mixing, reaction, and distillation. These processes require accurate flow measurement to control the quality and efficiency of the production process.

2. Petrochemical production: Vortex flow meters are used to measure the flow of fluids in various processes, such as oil refining, gas processing, and polymer production. These processes require accurate and reliable flow measurement to ensure product quality and safety.

3. Environmental monitoring: Vortex flow meters are used to monitor the flow of wastewater, sludge, and other effluent from chemical and petrochemical plants. These meters can measure the flow rate of the effluent, which helps in calculating the volume of pollutants released into the environment.

Advantages of Vortex Flow Meters

Vortex flow meters have several advantages over other flow measuring devices, such as electromagnetic flow meters and ultrasonic flow meters. Some of the advantages are:

1. High accuracy: Vortex flow meters provide high accuracy in flow measurement, even for low flow rates. They can measure flow rates up to 10,000 m3/h accurately.

2. Low pressure loss: Vortex flow meters have a low-pressure loss, which means there is less energy loss in the fluid flow. This reduces the energy consumption and lowers the operational cost.

3. Long-term stability: Vortex flow meters have a stable long-term operation, which means they require less maintenance and have a longer service life.

Conclusion

Vortex flow meters play a critical role in measuring and monitoring the flow of process fluids in chemical and petrochemical industries. They offer high accuracy, low pressure loss, and long-term stability, making them an ideal choice for flow measurement.
