Measuring gas; the differential pressure transmitter is below the pressure sensing element

If the gas doesn’t condense, then lead the pressure gauge tube to the ground and connect it to a differential pressure gauge – that’s it. Monkeys, laugh {:2_40:} {:2_42:} {:2_45:} {:2_33:} {:2_36:}

Look, HG/T21581 has such installation diagrams. Make sure to properly drain at the low points.

If there really are liquid droplets, then install a tee on the pressure guiding tube, connect a section of pipe and a small container or something, so that the liquid droplets can flow to a place lower than that of the differential pressure gauge. Then, open the valve periodically to drain the accumulated liquid – and that’s it, right? :lol

Thank you! So if the gas contains hydrogen sulfide or flammable gases, should an isolation tank be installed?

Taking this topic as an opportunity to talk about some other related issues. In fact, such problems are nothing in the eyes of those who have experienced them before. As a newcomer, it’s quite convenient to call those who are more experienced around you \"master\" for advice. However, there are also some masters who are arrogant,,, The internet plays a certain role in this regard as well. Just do a search online, and it seems that basically everything can be solved. Why ask others for advice and let them look down on you? ? Or is there something else? ? On-site preaching is the most practical, and it can be backed up by guarantees from certain parties. I have also paid attention to such things. Young people these days are different from those in our generation; they enter the workplace already mature, working alone, and they turn to the internet for help. I’m not sure if this makes my analysis correct. Here, I advise these young students to be good at seeking advice from those around them, especially their assigned teachers. If there are any objections, they can be sent in for verification; this is a better way of learning. It’s just discussion; it’s not directed at any individual. For reference.

For non-corrosive gases, it is sufficient to connect the pressure line directly to the transmitter; however, a drain valve is required for regular drainage...

Well said. One should make good use of the skilled craftsmen available around them. This actually reflects another issue: today’s young people are not very willing to communicate with others. In fact, interpersonal relationships in society are a complex subject, and everyone needs to learn something about it to some extent

Instead of relying on others, one can turn to the internet; this provides a broader perspective and reduces the chances of making mistakes. If one goes a step further and can often use search engines to discover the essence of knowledge from fields unrelated to their own, as well as find the correct answers to difficult and unusual questions, then that’s truly amazing – such a person can be considered an expert. {:2_45:}

“Hydrogen sulfide or flammable gases – do they undergo significant chemical reactions with the sensor diaphragm? It doesn’t react, right? To fully understand this matter, one needs to consult the material corrosion tables and the corrosion manuals. If there is no reaction, then no isolation tank is needed. Calling it doing something unnecessary is like saying it’s adding extra steps when none are needed. Let’s use a simple example: on any broken pipe, you can see a pressure gauge installed directly there; it shows how the pressure is changing, and that’s all there is to it. For stuff like this, don’t go asking your master. . . The master is just a few seedlings. When has Sun Wukong ever asked Old Tang about subduing demons and monsters? Lao Tang is just a showoff, Amitabha..... Guys, laugh, {:2_40:} {:2_42:} {:2_45:} {:2_32:} {:2_33:} {:2_36:}
