Where can I find information on the density of the inert liquid used to fill the capillaries in Rosemount differential pressure and pressure transmitters? How can I find this information? Thank you!
It’s best to ask the manufacturer; it’s straightforward. If you know the ingredients, you can look up the density under the relevant temperature and pressure conditions
Bro knows. Do you spend money on intelligence? In addition to the discount for you :P
Actually, telling you the density of silicone oil is completely useless – silicone oil manufacturers provide the density of the material at a specified temperature, but this isn’t a fixed value; rather, it’s within a certain range, with a difference of almost 0.1 g/cm3. The density also varies depending on the batch in which the product is manufactured. . . Speaking of silicone oil again, its thermal expansion is also quite significant; for a change of 1°C in temperature, the density change is roughly more than 0.001 g/cm3. So, it’s really difficult to come by any decent information about Lao Luo’s screw business in order to make some money from it. :lol
Differential pressure level calculation is sometimes needed; please be lenient.

After the differential pressure gauge is installed, the pressure reading indicated by it when the tank is empty corresponds to a liquid level of 0; this value is also what you refer to as the migration amount. The pressure reading on the differential gauge when the tank is full corresponds to the full liquid level; that is, (full-level reading – zero-level reading) = the operating range. The shortest distance between two points is a straight line — there’s no need to consider the density of silicone oil! It’s necessary to understand the density of silicone oil for wood! It’s necessary to understand the density of silicone oil for wood! Got it? There’s no need to worry about the density of the ball material liquid either. . . And what the actual value of gravitational acceleration is? Who the hell knows. . . The so-called calculation is simply taking off one’s pants, applying lipstick around the anus, and then letting out an inaccurate, smelly fart.
