What you need to know to influence the accuracy of the vortex flowmeter

As everyone pays more and more attention to environmental protection and energy conservation, our requirements for flow meters are getting higher and higher. And how to properly use the vortex flowmeter

This is a very complicated problem. Steam is an environmentally friendly energy source. Today's development is a good use of resources and has been widely used. Of course, with the increasing use of steam, various types of vortex flowmeters are constantly researching and producing to meet the needs of enterprises. How do we do the work of the vortex flowmeter? To ensure its use value.

The first point, the flowmeter is the influence of the measurement range used: each product has its range of use and pressure, and the vortex flowmeter is also the same, the right flow meter can be selected at the right place and in the right range. Produce the greatest use value. In the use of accurate budget work, choose the appropriate size of the caliber, in order to meet the authenticity of the measurement, and get accurate data.

The second point, pay attention to the measured medium environment: the parameters of different media environments are different. Obvious problems, when measuring liquid or solid, we must accurately set the parameters of the flow meter, which not only allows The value of the flowmeter is reflected in its own value, and it can give you a unique and accurate result.

Third, the choice of steam density is important: the density of steam is mainly calculated from its own temperature and pressure measurements. For steam, the calculated value of density is an important factor that directly affects the measurement. Calculate the results, we must make the correct compensation method by observing the actual state of the steam, in order to make better use of the vortex flowmeter. The above analysis may not be very extensive and comprehensive. If you have more needs, we will give a detailed introduction to what you need to know. At the same time look forward to working with you for exchanges and cooperation.

Since the intelligent gas flowmeter uses the cumulative flow value under standard conditions as the basis for measurement and trade settlement in actual work, in the actual measurement verification process, the natural gas flowmeter to be tested is connected in series with the standard or standard flowmeter. Together, the metrological verification is performed by comparing the flow values under the standard conditions. According to the existing national standards and verification procedures, in the actual verification work, only the flow sensor is verified, and the verification of the temperature and pressure sensor affecting the flow rate is neglected.

In the actual verification work, when the metering meter is out of tolerance, if the temperature and pressure indications are not easy to detect with the laboratory test medium temperature and pressure, only adjust the meter factor to ensure the flowmeter is in the laboratory environment. The agreement on the experimental data. However, because the laboratory testing environment is different from the temperature and pressure of the pipeline medium, leaving the laboratory environment will bring new errors, making the measurement accuracy of online work even more unguaranteed
