Vortex flowmeters are mainly used for flow measurement of industrial pipeline material fluids, such as gases, liquids, and steam. Due to the small pressure loss, wide range and high accuracy of vortex flow, it is almost unaffected by fluid density, pressure, temperature and viscosity when measuring working conditions. If a flow error is reflected in the use of a vortex flowmeter, the first thing to do is to distinguish this error, which leads to a flow deviation.

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 the field of modern industrial flow measurement, vortex flowmeters have become the preferred choice for measuring the flow of liquids, gases and steam due to their advantages such as simple structure, high reliability and wide application range. So, how does this star product achieve precise measurement? Let’s explore the scientific principle behind it.

With the continuous production progress of the reform and opening up industry, it has been applied in more and more industries, and the vortex flowmeter is widely used in large, medium and small pipeline water supply and drainage, industrial circulation, and sewage treatment.

The vortex flowmeter is used in measuring coke oven gas, and the coke oven gas in some coke plants has been developed in the direction of civil gas. As a result, the problem of gas measurement becomes more and more prominent, and the demand for accuracy of gas measurement becomes higher and higher. However, there will be some problems in use, let’s talk about the causes and solutions of these problems:

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 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:

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.

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.

1. Requirements for piping:

The inner diameter of the upstream and downstream piping at the installation point of the steam flowmeter is the same as the inner diameter of the flowmeter.

There are various types of flowmeters for measuring nitrogen, and each type has its specific application scenarios and advantages. The following are some common nitrogen flowmeters:

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 flow meters are highly versatile instruments widely utilized in various industrial applications to measure the flow of liquids, gases, and steam. One prominent application of vortex flow meters is in the oil and gas industry, where they play a crucial role in measuring the flow rates of hydrocarbons through pipelines. These meters are particularly adept at handling the challenging conditions present in oil and gas operations, including high pressures and temperatures. By accurately measuring flow rates, vortex flow meters contribute to efficient process control and optimization, ensuring that production and transportation systems operate smoothly and cost-effectively.

Vortex flowmeter is a kind of fluid oscillating flow detection instrument based on Karman vortex principle. It is characterized by small pressure loss, wide range and high measurement accuracy. It is almost unaffected by fluid density, pressure, temperature, viscosity and other parameters when measuring volume flow under working conditions. In daily use, there may be problems such as large measurement errors, so we need to eliminate problems from the following aspects:

The causes of faults in the on-site metering system of the steam flowmeter can be summarized into two major reasons: one is caused by the flowmeter or its related equipment; The second reason is not related to the flowmeter, that is, the flowmeter is normal, but the fault is caused by environmental or system reasons.

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.
