What special instruments are needed to measure oxygen and liquid oxygen?
Thread Content
For pressure, oxygen pressure gauges must be oil-free; but for parameters such as the liquid oxygen level, flow rate, and temperature, what kind of instruments are needed that differ from those used for ordinary media? ? Asked a question, a newbie in design!
Liquid oxygen is at low temperatures, so instruments made of materials suitable for low temperatures should be used
Pure oxygen is a strong oxidizing agent, while liquid oxygen is a cryogenic medium. When liquid oxygen vaporizes, it absorbs a large amount of heat, and its volume expands rapidly at the same time. Based on these characteristics, specific requirements are put forward for the selection of instruments.
