The advantages and disadvantages of vortex flow meter are analyzed

Reliability is a hallmark of vortex flow meters, as they exhibit robust performance in harsh operating conditions. Their simple yet sturdy design, often featuring no moving parts, results in minimal maintenance requirements and increased longevity. This reliability is particularly crucial in industries where consistent and accurate flow measurement is essential for process control and optimization.

Gas flowmeter is a general term for many measurable gas flows. Today, we mainly explain the installation conditions of vortex flowmeter.

Vortex flowmeter is mainly used for the flow measurement of industrial pipeline medium fluids, 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. There are no moving mechanical parts, so the reliability is high, the maintenance is small, and the instrument parameters can be stable for a long time.

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.

Vortex flowmeters are suitable for measuring the mass flow and volume flow of superheated steam, saturated steam, compressed air, general gas, water and low corrosive liquids. We often encounter the following failures in the use of vortex flowmeters:

Precautions for installation and use of vortex flow meter

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.

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 precession vortex flowmeter adopts advanced microprocessing technology, which has the advantages of strong function, wide flow range, simple operation and maintenance, convenient installation and use.

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 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?

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 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.

Vortex flowmeter is mainly used for the flow measurement of industrial pipeline medium fluids, such as gas, liquid, vapor and other media. In addition to the characteristics of the aforementioned vortex flowmeter, it also has the following characteristics:

When selecting the right air flow meter product, a number of factors need to be considered to ensure that the selected product can meet the actual needs and has good performance. Here is a detailed buying guide to help you choose the best air flowmeter:

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.

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 flowmeter common faults and solutions

Vortex flowmeter is a commonly used flow meter, the use of any instrument is inseparable from daily maintenance and maintenance, whether it is its own failure or interference by external factors, we calmly respond to the occurrence of failure.

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.

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.

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 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.
