Vortex Flow Meters: Components, Types, and Applications

 What are Vortex Flow Meters?

Vortex flow meters are the devices used to measure the flow rate and velocity of fluids–liquids, gases, and steam. They detect the frequency of vortices shed from a bluff body placed in the flow stream, a phenomenon known as the von Karman effect. The vortex shed frequency is directly proportional to the velocity of the fluid, which allows for accurate flow measurement. The vortex flow meters can measure volumetric flow, and with additional sensors, mass flow and energy flow.

Components

Below are the components of the vortex flow meter:

• Bluff Body: It’s a strategic obstruction placed in the flow stream that creates vortices in the flow of the fluid. Its shape and dimensions are crucial to ensure consistent and predictable vortex shedding.

• Sensor: A vortex flow sensor is a component used to detect the pressure fluctuations caused by vortices. Piezoelectric or capacitance sensors are the most common types of sensors.

• Transmitter: The vortex flow transmitter takes information from the sensor and converts it into electrical signals. The signals are then sent to the control system or display unit to present the final results.

• Meter Body: The meter body is the housing of all the components, and it is designed to withstand the pressures and temperatures of the fluid being measured. 

Types

Here’s an overview of vortex flow meter types:

• Standard Vortex Flow Meter: This device measures fluid flow by creating vortices. It is often used in applications where fluid density is relatively constant and volumetric flow measurement is sufficient. Also, it is generally cost-effective compared to multivariable meters.

• Multivariable (Pro-V) Vortex Flow Meter: A multivariable vortex flow meter measures temperature and pressure to deliver an accurate mass flow rate for gases, liquids, or steam.

• Insertion Vortex Flow Meter: Insertion vortex flow meters are used to measure flow in large pipes. They offer a cost-effective solution for large-diameter pipes.

Applications

Vortex flow meters are used in a wide range of applications. Let’s take a look at some of them:

• Vortex flow meters are used in the food and beverage industry to measure the flow of liquids like milk, juice, beer, and syrup. Their accuracy and nonintrusive nature maintain product quality and consistency. The meters also monitor steam used in cooking processes to ensure the steam’s amount is accurate.

• In the oil and gas industry, vortex flow meters are crucial in monitoring the flow of natural gas, crude oil, and other fluids through pipelines. They ensure that operations run efficiently and smoothly.

• In HVAC systems, flow meters measure air, steam, and water flow to ensure efficient and consistent heating and cooling operations.

• Chemical and petrochemical industries leverage vortex flow meters to measure the flow of chemicals, gases, and liquids. The flow meters provide reliable flow measurements to maintain consistent production and ensure safety.

• Vortex flow meters are also used in power generation industries to measure steam and water flow, optimize efficiency, and monitor system performance.
