What size should be chosen for air volume measurement?
Thread Content
Hello everyone. Due to the requirements regarding straight pipe sections for secondary air measurement, I would like to choose an air volume measurement device. It seems that several products, those with FWS92 and those with SZJL, are all based on the Pitot tube design – essentially in a back-to-back configuration. I’m not quite sure what purpose the probe used for measuring total pressure (dynamic pressure) serves, or how it prevents clogging; I really don’t understand how this total pressure sensor works or how it manages to prevent blockages A knowledgeable person recently provided a detailed analysis and explanation
The pressure of a fluid includes dynamic pressure and static pressure, and the total pressure is the sum of these two.
2# jujiangliu I’m aware of this relationship. I’m not very clear about the structure of his so-called sensors – how does it manage to prevent blockages?
