Several compensation methods of vortex flow meter

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:

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.

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.

1. There is fluid flow in the pipeline after power-on, but no signal output

The insertion vortex flowmeter is mainly used for the flow measurement of large-diameter gas, liquid and steam medium in industrial pipelines. In order to ensure the accuracy of its measurement, the following points should be noted when installing:

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 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:

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 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:

Whether the temperature and pressure compensation is required for steam measurement by vortex flowmeter mainly depends on the properties of the steam being measured and the requirements of measurement accuracy.

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.

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 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 flow meters:

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

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.

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 mature density measuring instrument has not been successfully applied, which brings certain difficulties to the steam flow measurement.

The structure of the vortex flowmeter is relatively simple, only the sensor and the display instrument are composed of two parts, and the measurement accuracy and stability are also relatively stable.

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 flow meters offer a cost-effective solution for flow measurement. Their relatively simple design, coupled with low maintenance requirements, contributes to a lower total cost of ownership over the life of the instrument. This cost efficiency, combined with their accuracy and reliability, positions vortex flow meters as a favorable choice for industries seeking optimal performance without compromising on budget considerations.

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

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 vortex flowmeter can measure the flow rate of the medium by calculating the vortex separation frequency.

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:

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.

To play a greater role, the vortex flowmeter must be correctly selected, and the selection is mainly judged by the temperature, pressure, flow rate of the medium, interference and other problems in the working condition.

The split vortex flowmeter is a kind of flowmeter suitable for measuring steam at high temperature, which can avoid the influence of interfering signals on the measurement of the instrument. So what are the characteristics of the split vortex flowmeter?

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, and relatively high performance price characteristics.
