The installation of the vortex flowmeter has different provisions, used to measure different measured media, different positions, then the installation method is not the same, the attention point is different, generally speaking, the vortex flowmeter has the following specified points:

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:

Vortex flowmeter common faults and solutions

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

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 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.

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.

As industries continue to seek efficient and reliable flow measurement solutions, vortex flow meters stand out for their accuracy, adaptability, and durability. Their ability to provide real-time data and facilitate process optimization makes them indispensable tools for ensuring the efficient operation of various industrial processes where precise flow measurements are essential.

At present, there are many misunderstandings about steam measurement in China, and many users often think that buying a high-price flowmeter can get accurate measurement results. The measurement of steam is different from other fluids such as water, air and other media, and there are many factors affecting its measurement in the actual measurement. Therefore, there is often a phenomenon that the flow meter itself is qualified, but the actual measurement is not “allowed”. So what’s the problem with these factors?
