Ordinary pressure gauge with isolation tank or diaphragm pressure gauge
Thread Content
I have a gentle question: which of the above methods is better for use with heavy oil? A. Ordinary pressure gauge with isolation tank ； B. Diaphragm gauge ； Explain the differences between the two! Examples with on-site experience would be better! ! Thank you! !
It is better to choose a tank with isolation; otherwise, sticking may occur, leading to inaccurate measurements!
It is recommended to use diaphragm pressure gauges; heavy oil is quite viscous and can easily cause blockages in the Bourdon tube
Both should work; in practical projects, the method of using isolation tanks is quite common. Constructing with an isolation tank is rather troublesome
We use diaphragm pressure gauges here.
A running-in pressure gauge should be used. In our factory, heavy oil is always handled with diaphragm gauges; otherwise, blockages or coking can occur, making it very difficult to clear things up
The wrong model was chosen for B; it should be a diaphragm pressure gauge, not a bellows type. Hehe. I would like to ask whether an isolation fluid or something similar is needed for diaphragm pressure gauges? Is there any maintenance needed on a daily basis?
Does a diaphragm pressure gauge require any regular maintenance? I have a separate tank filled with isolation fluid; won’t this cause blockages in the spring tube?
Let me correct one thing: it should be a diaphragm, not a diaphragm box. Diaphragm boxes are used for measuring small ranges of vacuum levels! I saw it after I sent it; thank you! ! Learn together*, progress together! !
Overall, diaphragms tend to stick together, so it is recommended to use isolation tanks along with isolation fluid!
It is best to use a flanged diaphragm pressure gauge.
