Gas Measurement Selection Guide: Is a Precession Vortex Flow Meter Right for Your Application?

In the process of using the steam flowmeter, we may encounter some minor failures, do not panic after the problem, find out how to deal with is the key. The following introduces several common faults of steam flowmeters and their solutions.

Accuracy is another significant advantage of vortex flow meters. With advancements in technology, modern vortex flow meters can provide precise and repeatable measurements even in challenging flow conditions. This high level of accuracy makes them indispensable for applications where tight control over fluid flow rates is critical, such as in chemical manufacturing or custody transfer operations in the oil and gas industry.

Vortex flow meters offer a host of advantages that make them a preferred choice in various industrial applications. One key advantage is their versatility in measuring the flow of liquids, gases, and steam. Unlike some other flow measurement technologies, vortex flow meters can handle a wide range of fluids, making them suitable for diverse industries such as oil and gas, water treatment, chemical processing, and HVAC systems.

Vortex flowmeter is also known as Karman vortex flowmeter. It is a separation flowmeter made of the principle of natural oscillation of fluid. When a fluid flows at a sufficiently large velocity through an object perpendicular to the direction of the fluid, if the object is of appropriate size, it will produce a neatly aligned and reversed vortex train behind the object along two parallel lines.

Vortex flowmeter has high requirements for installation and working environment, and the front and rear straight pipe sections must be installed in accordance with the specifications.

Vortex flowmeter is widely used because of its wide range, small pressure loss, medium accuracy, linear output, no moving parts, high reliability, small maintenance, medium low price, relatively high performance and price characteristics.

The measurement accuracy of the steam flowmeter is closely related to the pressure and temperature of the steam. Pressure compensation is recommended for measuring saturated steam, while temperature and pressure compensation is adopted for measuring superheated steam.

There are many types of flow meters for measuring nitrogen, and each type has its specific application scenarios and advantages. Here are some common nitrogen flowmeters:

Vortex flowmeter is a kind of instrument device to measure the flow of pipeline fluid, and it works by the principle of velocity vortex. Vortex flowmeter has two kinds of volume and mass flow measurement, which can be selected according to the situation of the field.

In the selection process of the vortex flow meter, in addition to the selection of a high-precision type in a comprehensive consideration of the demand, other accessories of the vortex flow meter are also very important, such as the selection of flow transmitters, the selection of compensatory pressure transmitters, and so on.

Gas flowmeters should be installed indoors as much as possible. If they are installed outdoors, measures should be taken to avoid direct sunlight and prevent rain.

Due to the compressibility of the gas, its flow measurement is more complex than that of the liquid, and the output signal of the vortex flowmeter is related to the gas density in addition to the input signal, and the density of the gas is a function of temperature and pressure (referred to as temperature and pressure).

Vortex flowmeter can be widely used in large, medium and small kinds of pipeline water supply and drainage, industrial circulation, sewage treatment, oil and chemical reagents and compressed air, saturated and superheated steam, natural gas and various media flow measurement and can be used as a flow transmitter in automatic control system, long service life. Points of attention for vortex flowmeter installation:

The installation of the vortex flowmeter has different provisions, used to measure different measured media, different positions, then the installation method is not the same, the attention point is different, generally speaking, the vortex flowmeter has the following specified points:

Vortex steam flowmeter is one of the main flowmeter products, widely used in petroleum, chemical industry, metallurgy, heating and other departments. Test and measure the flow of liquid, gas and steam.

In the realm of water and wastewater treatment, vortex flow meters are indispensable tools for monitoring and controlling the flow of water through pipelines. Municipalities and industrial facilities rely on these meters to measure the volume of water being processed and distributed, facilitating efficient water management. Additionally, vortex flow meters are often employed in chemical processing plants to measure the flow rates of various chemicals and ensure precise dosing in manufacturing processes. Their robust design and resistance to corrosive substances make them well-suited for these demanding environments, contributing to the overall reliability and accuracy of industrial processes.

1, pulse vortex flowmeter is a kind of high measurement accuracy, simple installation, small maintenance, a wide range of meters, is currently widely used in petrochemical, metallurgy, textile, urban construction, energy and other industries.

In the future operation of steam flowmeters, the inaccurate measurement or unusable situations caused by incorrect selection should be greatly reduced. The following points should be noted:

In industrial process control, energy measurement and gas/liquid flow monitoring, vortex flowmeters have become an important choice for flow measurement due to their advantages such as simple structure, wide range and high stability. However, in the face of different working conditions and application requirements, how to make the correct selection is of vital importance. This article will start from the key parameters to provide you with a detailed analysis of the selection points of vortex flowmeters, helping you achieve the best configuration.

Some common problems that may occur in the normal application of intelligent vortex flowmeters

Vortex flowmeter is based on the Karman vortex street principle, which is mainly performed by setting a non-streamlined vortex generator (resistance fluid) in the flowing fluid, and alternately producing two columns of regular vortices from both sides of the vortex generator.

Whether vortex flowmeters need temperature and pressure compensation when measuring steam mainly depends on the nature of the steam being measured and the requirements for measurement accuracy.

Vortex flowmeter is also known as Karman vortex flowmeter. Vortex flowmeter is a kind of separation flowmeter made by using the principle of natural oscillation of fluid. When a fluid flows at a sufficiently large velocity through an object perpendicular to the direction of the fluid, if the object is of appropriate size, it will produce a neatly aligned and reversed vortex train behind the object along two parallel lines.

Vortex flowmeter is a velocity flowmeter, which measures the volume flow rate in the working state. If you choose the table according to the volume flow rate, the mass flow rate provided by the customer should be converted into the volume flow rate under the working state, and then determine the diameter of the selected instrument against the volume flow parameter.

Vortex flowmeters, as a commonly used flow measurement instrument, have extensive applications in the industrial field. The following is a detailed analysis of the advantages and disadvantages of vortex flowmeters and their selection guidelines:

Nominal diameter: DN25～DN300mm
Accuracy: liquid ±1.0%, gas (steam) ±1.5%, plug-in ±2.5%

LUGB flange clamped vortex street steam flowmeter is a commonly used structure, its body itself does not have a connection flange, in connection with the pipe, the flowmeter clamped between two special flanges, and then bolted.

Vortex flowmeters are not only suitable for measuring a variety of low viscosity liquids, but also mainly for industrial measurement of gases and vapors. When measuring the volume flow of gas, vortex flowmeters are not affected by changes in fluid temperature, pressure, density, viscosity and other properties, so the measurement is very accurate and is the first choice for measuring air.

In modern industrial production, efficient and accurate flow measurement is the key to ensuring process stability and improving energy efficiency management. Vortex flowmeters, with their advantages of simple structure, high reliability and wide application range, have become the “main force” in flow monitoring in industries such as petrochemicals, energy and power, metallurgy and pharmaceuticals, providing solid support for the intelligent upgrade of industry.
