Vortex flow meter is a commonly used flow measurement instrument, suitable for flow measurement of various liquids and gases. It has the advantages of high precision, stability and reliability, so it is widely used in many fields. However, in actual applications, Vortex flow meter are not suitable for all situations. Below we will introduce in detail the situations where Vortex flow meter are not suitable.

1. High-viscosity liquids Vortex flow meter are mainly suitable for flow measurement of liquids and gases. However, for high-viscosity liquids, due to their greater viscosity, the resistance flowing through the Vortex flow meter is greater, which can easily lead to inaccurate flow measurement, so they are not suitable for flow measurement of high-viscosity liquids.

2. High-temperature medium The turbine and sensor inside the Vortex flow meter are generally made of metal materials. For high-temperature media, it is easy to cause thermal expansion and contraction of the turbine and sensor, resulting in inaccurate measurement and equipment damage. Therefore, flow measurement in high-temperature media is not suitable for Vortex flow meter.

3. High-pressure medium The installation position of Vortex flow meter is generally located upstream of the pipeline. Therefore, for high-pressure medium, due to the high pressure flowing through the Vortex flow meter, it is easy to cause damage to the turbine and sensor, and it will also affect the measurement accuracy. Therefore, flow measurement under high-pressure medium is not suitable for Vortex flow meter.

4. The liquid contains particulate matter. The turbine and sensor inside the Vortex flow meter are generally made of metal materials. When the liquid contains particulate matter, the particulate matter can easily cause wear and damage to the turbine and sensor, and will also affect the measurement accuracy. Therefore, it is not suitable for flow measurement of liquid containing particulate matter.

5. The liquid contains bubbles. When the liquid contains bubbles, it is easy to interfere with the rotation of the turbine, resulting in inaccurate measurement. Therefore, when the liquid contains bubbles, it is not suitable for flow measurement of the Vortex flow meter.

In short, although the Vortex flow meter has many advantages, there are also situations where it is not applicable in practical applications.

The correct usage is: To maximize its use, you need to pay attention to the following aspects:

1. Selection of installation location

The accuracy and stability of the Vortex flow meter largely depend on the choice of installation location. During installation, bends and bulges in the pipeline should be avoided as much as possible to ensure that the fluid can fully flow through the Vortex flow meter and to avoid bubbles and solid particles in the fluid from gathering near the flow meter. In addition, the Vortex flow meter also needs to have a certain length in the pipe to ensure stable flow of fluid through the flow meter.

2. Choice of installation method

There are two main installation methods for Vortex flow meters: side mounting and direct mounting, which need to be selected according to the specific application scenario. Side mounting is suitable for pipes with small diameters and low flow rates, which can avoid changes in the cross-sectional area of ​​the pipe and deformation of the pipe structure. Direct installation is suitable for pipes with large diameters and high flow rates, which can avoid pipe bends and unstable flow.

3. Proper calibration and maintenance

The accuracy and stability of Vortex flow meter require regular calibration and maintenance. Before calibration, it is necessary to confirm the parameters and working conditions of the flow meter, such as the temperature, pressure, viscosity, etc. of the fluid. Calibration requires the use of a standard flow meter or weighing method to check the accuracy of the Vortex flow meter. At the same time, regular cleaning and maintenance are required to ensure the long-term stability of the flow meter.

4. Reasonable use environment and working conditions

Vortex flow meters need to work best under certain environmental and working conditions. When using, avoid high temperature, high pressure and highly corrosive media, and avoid excessive vibration and impact. In addition, it is also necessary to avoid the Vortex flow meter from being idle for a long time to avoid damage to the flow meter.

The Vortex flow meter is a very practical flow meter that can play a great role when used and maintained correctly. To maximize its usefulness, it is necessary to choose the appropriate installation location and method, correct calibration and maintenance, and operate under reasonable usage environment and working conditions.

The accuracy and stability of the Vortex flow meter largely depend on the choice of installation location and installation method. The right choice can maximize the effectiveness of its measurements. This article will introduce in detail how to choose the installation location and installation method of the Vortex flow meter to ensure the accuracy and stability of the flow meter.
