Measuring principle
A fluid flowing with a certain velocity and passing a fixed obstruction generates vortices. The generation of vortices is known as Karman’s Vortices.The frequency of vortex shedding is a direct linear function of fluid velocity and frequency depends upon the shape and face width of bluff body. Since the width of obstruction and inner diameter of the pipe will be more or less constant, the frequency is given by the expression:
f=(St*V)/c*D

A vortex steam flow meter is a device used to measure the flow rate of steam or other fluids in a pipe. It works by measuring the frequency of vortices created by the fluid as it passes through a bluff body in the pipe. The vortex steam flow meter is particularly useful for measuring the flow of steam in power generation plants, where accurate flow measurement is crucial for efficiency and energy savings.
The FVC240 vortex steam flow meter consists of a sensor and a transmitter. The sensor has a bluff body that is placed in the pipe, causing vortices to form downstream of the body. These vortices create pressure fluctuations that are detected by a piezoelectric crystal in the sensor. The transmitter converts the piezoelectric signal into a flow rate measurement that can be used for process control.
The vortex steam flow meter is widely used in power generation plants, where it is used to optimize steam flow and energy consumption. It is also commonly used in other industrial applications such as chemical processing, oil and gas, and food and beverage production. It has several advantages over other flow measurement technologies, including high accuracy, low maintenance, and the ability to measure flows in high-temperature and pressure environments.
In summary, the vortex steam flow meter is a highly reliable and accurate device for measuring the flow rate of steam and other fluids in a pipe. Its versatility and ease of use make it a popular choice in a range of industrial applications where precise flow measurement is essential for process control and optimization.
Vortex shedding flow meters are commonly used in applications such as chemical processing, oil and gas, water and wastewater treatment, and food and beverage processing. They are used for measuring flow rates of liquids, gases, and steam in pipes and ducts. They can be used for batching and totalizing applications, where the total volume or mass of fluid over a period of time needs to be measured. They are suitable for applications where high accuracy and reliability are required, such as custody transfer applications or critical process control.
Vortex shedding flow meters are widely used in industrial process applications for measuring the flow of liquids, gases, and steam. Vortex shedding flow meters use the principle of vortex shedding to measure flow rate, which involves the frequency of vortices shed from a bluff body in the fluid stream. They can measure flow rate across a wide range of flow velocities, pressures, and temperatures. They have no moving parts, which makes them low maintenance and reduces the likelihood of clogging or damage. They are suitable for use in corrosive and abrasive fluids, and are often made of materials such as stainless steel or titanium.
