How to choose the gas thermal mass flow meter correctly

Abstract: How to correctly choose the gas thermal mass flow meter information is provided by the excellent flow meter and flow meter manufacturers and quotation manufacturers. How to choose the right gas thermal mass flow meter? Let's introduce it below. There is data to prove that in terms of the failure probability of flow measurement, improper flow meter selection accounts for about 70%, and flow meter product quality or other reasons account for 30%, which can be seen in the selection. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the article details on how to correctly choose a gas thermal mass flowmeter. How to choose the gas thermal mass flowmeter correctly? Let's introduce it below. There is data to prove that in the probability of failure in flow measurement, improper flow meter selection accounts for about 70%, and flow meter product quality or other reasons account for 30%. It can be seen how important the selection is to flow measurement. The user of thermal gas mass flowmeter should pay special attention not to choose a certain type of flowmeter, unless you choose to replace the original flowmeter, and leave this work to the seller, because they are professional. You just need to provide as complete as possible working condition data and some technical requirements. For example, the flow range (it is recommended to use the standard square for the flow unit), the medium to be measured, the diameter of the pipeline, the material of the pipeline, the working pressure, the working temperature, whether explosion-proof is required, the working environment temperature of the flowmeter, the signal power requirements, the accuracy level, and what is the application Technologically (process control or trade measurement), measure the dryness and cleanliness of the medium. When measuring the mixed gas flow, be sure to provide the percentage value of each medium. A final reminder: if the site has conditions, the flowmeter should be integrated. If it is split, since the transmission signal cable is part of the measurement bridge, it has resistance itself. No matter how well done, because the resistance of the measuring probe is very small, the resistance of this cable will inevitably affect the The calculation and processing of the electronic circuit, coupled with the influence of the on-site environment, the resistance value will drift. If you have to choose a split, it is recommended that the distance between the splits should be as short as possible. If the measurement gas is other gas medium other than air, it is recommended to choose a thermal flowmeter product with real flow calibration abroad, which must be remembered. Of course, unless you have low requirements for measured data, don't care how much deviation, just look at the flow trend, you can still choose those low-end thermal flowmeter products. For low-priced dumped products, pay more attention to yourself. Calculate the basic cost to see if it is a flowmeter product that can guarantee product quality. There is a basic cost that cannot be avoided. The most important thing to correctly choose a thermal gas mass flowmeter is to learn more, master the measurement principle and Product performance, and more in-depth communication with the product manufacturer's business personnel, to identify the characteristics of each brand. Only then can we base ourselves on ourselves and correctly choose thermal gas mass flowmeter products that meet our own requirements.
