What are the advantages and disadvantages of vortex flow meters?

The vortex steam flow meter is mainly used for measuring the industrial pipeline media fluid flow, such as gas, liquid, steam, and other media. The vortex flow meter has a very wide range of applications in petroleum, chemical, metallurgy, paper, and other industry sectors. However, any instrument in its product performance will have certain limitations. The vortex flow meter is no exception.

The vortex flow meter has a wide range ratio and high measurement accuracy. The vortex gas flow meter range ratio is generally 10:1. The vortex shedding flow meter can adapt to the measurement of occasions where the flow size fluctuates frequently. Vortex shedding flow meter measurement accuracy is generally 0.75% to 2.0%, and this measurement accuracy in the flow meter for the high level.

The output signal of the vortex shedding flow meter is a digital pulse signal. This digital signal is easy to connect with the computer interface and is not affected by temperature changes. The vortex flow meter has no zero drift, no signal hysteresis, and easy to accumulate measurements.

The vortex flow sensor can measure the flow of gas, steam, and liquid. The vortex flow sensor can also measure the flow of high-temperature, high-pressure, corrosive, and dirty media. Vortex flow sensor has good adaptability and versatility. The flow coefficient of the vortex flow sensor is not affected by changes in the physical parameters of the medium, such as temperature, density, viscosity, and so on. In other words, the coefficient of the vortex gas flow meter remains unchanged under the working condition. This characteristic makes the vortex flow sensor easy to use and simple to calibrate.

The vortex gas flow meters are easy to install, reliable, and low maintenance. There is no pressure -conducting pipe and no special insulation measures are required. Therefore, the vortex gas flow meter is easy to install and has a low failure rate. The vortex flow meter has a simple structure and stable flow coefficient. Generally speaking, if the vortex generator and vortex gas flow meter body structure do not change, then the meter coefficient will not change.

The vortex gas flow meters are characterized by low-pressure loss compared to other mechanical flow meters. The vortex flow sensor is a kind of energy-saving flowmeter.

But the vortex steam flow meter also has limitations.

The vortex flow sensor is a kind of fluid vibration type flow measurement instrument. The vortex flow meter vibration resistance compared with velocity gas flow meter is poor. Especially in the stress type measurement state, this problem appears more prominent. Therefore, the vortex flow meter should not be used in the pipeline vibration is relatively strong occasions. If you need to use a vortex shedding flow meter on vibration occasions, then you should take appropriate measures.

The vortex shedding flow meter for the measurement of dirty media adaptability is poor. The generator body of the vortex steam flow meter is very susceptible to entanglement by dirty media. It can have a significant impact on the measurement accuracy.

The vortex steam flow meters have a relatively poor temperature resistance. Generally speaking, the vortex steam flow meter can only measure the fluid flow of media below 300℃.
