Vortex flowmeters are more popular than orifice flowmeters

Now the steam flow meter is more and more widely used, we are more used in real life, then the principle of the steam flow meter it is what? Now let me give you a brief overview. Its principle, it is based on the Karman vortex street principle to measure gas and steam, as well as liquid volume flow and volume flow or mass flow volume flowmeter, it can also be used as a flow transmission, and applied to automated control system, and it is the use of more advanced plug-in technology, and then with isolation shield filtering and so on some measures, Thus, it overcomes some problems such as poor shock resistance and small signal data disorder among similar products.
And the use of some unique sensor packaging technology, as well as some protective measures, so as to ensure the reliability of the product, and then the product is divided into two forms of basic and composite basic type, it is to measure a single flow signal and composite, it can not only measure a single flow signal, it can also observe the realization of temperature and pressure, There is also a measure of flow, which has an overall structure for each form. As well as a separate structure, it can be installed to adapt to different installation environments. Steam flowmeter measurement principle it is saturated steam gas, flow measurement in the 1980s people are generally used a standard orifice flowmeter, but from your current flow expected development situation, orifice flowmeter although its history is relatively long, the scope of application is particularly wide, but people's research on it is also very full, The trial data are relatively complete.
However, with this kind of flow meter to measure the saturated steam flow, it still has some shortcomings, first of all, its pressure loss is relatively large, second, it is easy to reverse the pressure tube, three components and connection joints are easy to leak. The third is that its range is relatively small, the flow fluctuation is large, the tutorial measurement value is low, and relatively speaking, it has a simple structure. The transmitter is mounted directly on the pipe, thus overcoming some of the phenomena that the pipe is easy to leak. In addition, the pressure loss of the vortex flowmeter is relatively small, its measurement defense is very broad, and then proportional to the saturated steam side measurement, so with the maturity of the vortex steam flowmeter measurement technology, the use is now more and more favored by people.
