What would you like to know about Coriolis mass flow meters?

This post was last edited by A Chao syc62100 on 2017-4-25 06:59. I would like to ask fellow sailors: 1. In principle, does the mass flow rate measured by a Coriolis mass flow meter depend on the medium? From the perspective of the theoretical derivation, it seems unrelated. Can it be said that, in theory, a Coriolis mass flow meter can be used to measure the mass flow rate of any type of fluid? :Lol 2. In addition to mass, a Coriolis mass flow meter can also measure density and temperature directly. Can it measure pressure as well? 3. Is the density measured by the Coriolis mass flow meter the density under actual operating conditions, or is it the density under standard conditions after conversion? Thank you! :)
The question raised by the original poster is quite comprehensive. It gives me the impression that you understand it at the same time as not understanding it; I’m not sure whether you do understand it or not!
1. Independent of the medium. Of course, think about it again: any derived formula has underlying conditions; if those conditions are not met, then the formula does not exist ； Any measuring instrument has its limitations; how can one find a flowmeter that can measure the flow of any medium? Not to mention mass flow rate. So you need to pay more attention to the application ranges, advantages, and disadvantages of various flowmeters. 2. Density is measured, while temperature is measured using a separate thermometer; this is essential. Pressure does not have to be measured; if it is, it is measured by a separate pressure gauge. 3. Density under actual operating conditions requires no conversion. Remember, mass flowmeters are most commonly used to measure the mass flow rate as well as the density of the fluid under actual operating conditions.
I’m sorry, Pig Brother – the flow meter textbook is full of numerous derivation formulas, which really confuses me: lol
Yeah, it’s a bit unclear. I checked the books, but they didn’t explain it clearly either, so I asked other users for help: lol
Actually, you’ll get a lot of useful information by searching for posts on quality mass flow meters on the Haichuan Forum!
