Gas flow measurement method
Thread Content
Can anyone provide the current gas flow measurement method (excluding water vapor), the use range of each flow meter, and an approximate quotation~~Thank you!!!!
Please explain the medium in detail so that friends can post correct answers: lol
The medium other than water vapor, such as air\N2\O2\CO\water gas, etc., as long as it is not water vapor, it is fine.~~
The types of flow meters that can be used are: Thermal mass flowmeter, rotor flowmeter, turbine flowmeter, orifice flowmeter, velocity averaging tube flowmeter, ultrasonic flowmeter, waist wheel flowmeter, etc. can be used to measure gas flow. The key is to look at the required accuracy, medium, working conditions, etc.
Thank you 4# for your answer. What I want to know now is the working principle and usage range of each flow meter, as well as which manufacturer of each flow meter is relatively better and its approximate price.~~
my email jlb91@163.com Thank you "Sha Po Lang" Haiyou! :loveliness:
It is best to first explain the specific parameter requirements and working conditions in detail to accurately select the model.
Gas flow meter prices are skyrocketing. It cost 700 yuan in 2007. I just bought one a few days ago and it cost 1,200 yuan.
The key is that I don’t know the specific parameters. The leader asked me to look up some gas flow measurement methods. It doesn’t have to be water vapor. The scope is too wide. I don’t know how to proceed. I just searched for a long time on Baidu and reluctantly scraped together some words.~~
If you are measuring air volume, you can choose a thermal gas mass flow meter or a Deltabar flow meter, both of which are suitable for large pipe diameters and have relatively high accuracy. The applicable scope of working conditions is also relatively wide. If the requirements are not high, you can choose throttling devices such as orifice plates and wings.
