What technical parameters need to be understood before selecting a vortex flowmeter

Gas flowmeters should be installed indoors as much as possible. If they are installed outdoors, measures should be taken to avoid direct sunlight and prevent rain.

Vortex flow meters offer a host of advantages that make them a preferred choice in various industrial applications. One key advantage is their versatility in measuring the flow of liquids, gases, and steam. Unlike some other flow measurement technologies, vortex flow meters can handle a wide range of fluids, making them suitable for diverse industries such as oil and gas, water treatment, chemical processing, and HVAC systems.

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:

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.

In the selection process of the vortex flow meter, in addition to the selection of a high-precision type in a comprehensive consideration of the demand, other accessories of the vortex flow meter are also very important, such as the selection of flow transmitters and the selection of compensatory pressure transmitters.

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 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.

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.

The advantages of vortex flowmeters

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 HVAC (heating, ventilation, and air conditioning) systems, vortex flow meters are utilized to measure the flow rates of air and other gases. Their ability to provide accurate readings in a wide range of temperatures and pressures ensures efficient HVAC system operation. Vortex flow meters contribute to energy savings by enabling precise control of airflow and facilitating better management of heating and cooling processes.

Across various industries, including pharmaceuticals, food and beverage, and power generation, vortex flow meters continue to find applications in processes requiring precise fluid flow measurement. Their adaptability to different fluid types, low maintenance requirements, and reliable performance make them indispensable tools for optimizing industrial processes and ensuring the accurate allocation of resources.

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.

In the process of diameter selection of vortex flowmeter, special attention should be paid to the fact that the diameter of vortex flowmeter cannot be selected according to the original pipe diameter on site. The diameter of the vortex flowmeter should be determined according to the parameters in the pipeline such as the flow range of the medium in the pipeline, working temperature and working pressure, and then combined with the technical parameters of the vortex flowmeter.

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. This article will start from the key parameters to provide you with a detailed analysis of the selection points of vortex flowmeters, helping you achieve the best configuration.

Insertable vortex flowmeters are widely used in the measurement of steam, gas and liquid flow due to their advantages such as simple structure, easy installation and low cost. However, in practical applications, its measurement performance is limited by multiple factors. If the selection or use is improper, it may lead to data deviation or even equipment damage. This article will conduct an in-depth analysis of the main limitations of the insertable vortex flowmeter to help users make reasonable selections and optimize their usage.
