Vortex flowmeters, with their simple structure, high reliability and wide application range, occupy an important position in the field of industrial flow measurement. However, its measurement accuracy is affected by multiple factors, and how to ensure high-precision measurement has become a core issue of concern for users. This article will analyze the accuracy guarantee strategies of vortex flowmeters from the perspectives of design, installation, calibration and maintenance.

Vortex flowmeters play an important role in the measurement of steam, gas and liquid flow due to their simple structure, high reliability and wide application range. The probe, as its core sensing component, directly affects the measurement accuracy and stability of the instrument. This article will comprehensively analyze the key technologies of vortex flowmeter probes for you, helping you make a worry-free selection!

The working principle of vortex flowmeter is to place a non-streamlined vortex generator in the fluid, so that the fluid is alternately separated on both sides of the generator, releasing two series of regularly staggered vortex flowmeter. In a certain range, the vortex separation frequency is proportional to the flow rate, and the flow rate of the medium can be measured by calculating the vortex separation frequency.

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.

When the vortex flowmeter has no liquid flow in the pipeline, the receiver counts abnormally due to the noise generated by the pipeline vibration, and the sensitivity of the instrument should be adjusted.

Vortex flowmeter common faults and solutions

Vortex flowmeters are versatile instruments commonly used in various industries for fluid flow measurement. Here are some applications of vortex flowmeters in different industries:

Vortex flowmeter is a kind of flow measuring instrument widely used in the industrial field. Its superior performance and versatility make it play an important role in the measurement of liquid and gas medium. Vortex flowmeter can not only measure a variety of liquid media, but also suitable for a variety of gases, providing reliable flow data support for industrial production and process control.

1. Vibration effect

Compressed air is generated by air compressor or high pressure fan. When these devices are in operation, they all have varying degrees of vibration, and sometimes the vibration is relatively strong, and this vibration is transmitted through the connecting pipe. When selecting and determining the position of the vortex flowmeter, this influencing factor should be fully considered. In various detection methods, the anti-vibration performance of the instrument is not the same due to different detection components. For the vortex street of the detection element, the vibration resistance can reach 0.5~1G. When determining the installation position of the vortex flowmeter, it should be as far away from the power equipment such as air compressors and fans as possible.

Vortex flowmeter is a new flowmeter successfully developed on the basis of Karman vortex principle. Vortex flowmeter is suitable for measuring the mass flow and volume flow of superheated steam, saturated steam, compressed air, general gas, water and low corrosive liquid. How to ensure the accuracy of vortex flowmeter measurement during installation?

In chemical processing plants, vortex flow meters play a crucial role in measuring the flow of corrosive or abrasive liquids. Their resistance to harsh chemical environments, combined with their ability to offer accurate readings even in challenging conditions, makes them valuable assets for ensuring the efficiency and safety of chemical processes. The meters’ capability to handle different fluid types and maintain accuracy contributes to their widespread adoption in chemical industries.

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.

As a very special medium, steam will show special phenomena and problems in the process of vortex flowmeter measurement. The key problem is that the vapor density value deviates too much from the design value, which brings significant measurement errors to the measurement results. At present, the density measuring instrument with mature technology has not been successfully applied, which brings certain difficulties to the steam flow measurement.

Precautions for installation and use of vortex flow meter

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.

Another notable application of vortex flow meters is in the field of HVAC (Heating, Ventilation, and Air Conditioning) systems. These meters accurately measure the flow of chilled water or air, providing essential data for optimizing system performance and energy efficiency. By monitoring flow rates in HVAC systems, vortex flow meters help maintain ideal conditions in buildings, ensuring proper temperature control and minimizing energy consumption. In summary, vortex flow meters find widespread application across diverse industries, offering a reliable and cost-effective solution for measuring fluid flow in a variety of challenging environments.

Vortex flowmeter is one of the commonly used instruments in daily production, therefore, failure will occur from time to time, the main reasons for the inaccurate flow accuracy of the vortex include: the influence of temperature on the measurement, the influence of the accumulation of the vortex generating body on the flow surface, the influence caused by the inconsistency between the distribution tube and the inner flow meter.

The vortex flowmeter is based on the Karman vortex street principle. It is mainly characterized by setting up a non-streamlined vortex generator (blocking the fluid) in the flowing fluid, and alternately generating two regular vortices on both sides of the vortex generator. It is widely applicable to industries such as petroleum, chemical engineering, metallurgy, thermal power, textile, and papermaking, for the measurement and control of superheated steam, saturated steam, compressed air, and general gases, water, and liquids.

For energy measurement

Energy can be classified into primary energy, secondary energy, etc. Energy measurement is the scientific management of energy to achieve energy conservation and consumption reduction.

The intelligent vortex flowmeter can measure air. The vortex flowmeter is a new type of flowmeter that measures flow based on the Karman vortex street principle. It has excellent medium adaptability and can directly measure the working volume flow of various media (including air).

Vortex flowmeter is mainly used to set up a vortex generating body (resistance fluid) in the fluid, from both sides of the vortex generating body alternately to produce regular vortices, to measure the flow of fluid, vortex flowmeter is mainly used for industrial pipeline fluid flow measurement, such as gas, liquid, steam and other media. It is characterized by small pressure loss, large range, high accuracy, and is almost not affected by fluid density, pressure, temperature, viscosity and other parameters when measuring volume flow under working conditions. In daily use, the output signal may be unstable, causing this phenomenon to be excluded from the following points:
