Popular science: which flowmeter can be used to measure nitrogen?

To measure nitrogen, we can use a v-cone flowmeter. First of all, let me briefly introduce what is nitrogen. Nitrogen is a gas with no smell and no color. Although nitrogen contains a lot of oxygen, its properties are very unstable. It can be solved by using the v-cone flowmeter. The v-cone flowmeter is one of the more common measuring instruments on the market. It has the characteristics of good stability, high precision, and convenient later maintenance. Moreover, the v-cone flowmeter is resistant to The advantages of high temperature and high pressure resistance, so using v-cone flowmeter to measure nitrogen is the most suitable choice.
