Seeking advice on related issues in GB50131-2007?
Thread Content
Everyone, there is a question that has been bothering me: Paragraph 4.3.2 of section 4.3 on pressure transduction elements in GB50131-2007 states that \"when the pressure transduction element and the temperature transduction element are located on the same pipe segment, the former should be installed on the upstream side of the latter.\" How should this statement be understood? I heard from an experienced colleague on site that this one doesn’t seem to be very important. Under what circumstances is it installed in this way? Specific requirements? Thank you!
I’m not entirely sure either, but in practice there seems to be no noticeable impact. When measuring temperature, it’s important to avoid the formation of vortices and dead zones, and pressure doesn’t exhibit such phenomena at either the front or back positions; I don’t understand this
Why aren’t more people coming to discuss (give advice)? I hope everyone will share more opinions and views!
It does have an impact; when it is installed after the temperature sensor, vortices are formed in the pressure-taking section, resulting in pressure fluctuations. The greater the pipeline pressure, the more pronounced these fluctuations become.
