What is the best method of measurement for easily vaporizable low-temperature liquid materials?
Thread Content
The workshop uses pure trimethylamine in the production process; it is a liquid that vaporizes easily at low temperatures, with a boiling point of just over 3 degrees, making it quite easy to vaporize. I now want to measure the amount of trimethylamine being transported using some kind of measurement method; are there any mature measuring instruments available for this purpose? Electronic scales have large errors and are also cumbersome to use; mass flow meters are expensive, and it seems they also have significant errors for materials that are prone to vaporization. I’m asking the teachers for help – are there any good solutions? Thank you!
Can insulation be used to prevent vaporization? :lol:lol
It is best to maintain it in a low-temperature liquid state for measurement; or it is also acceptable to let it fully vaporize and measure it as a gas. Partial vaporization is the most troublesome, while measuring a two-phase mixture of liquid and gas is difficult and results in inaccurate measurements.
Measuring two-phase flow is a bit difficult.
