Hydrogen sulfide, a new type of pneumatic ball valve for natural gas gathering and transmission, is a highly toxic gas, which will have a great impact on human body and the environment. Because the natural gas transported by pipeline contains a large amount of hydrogen sulfide before desulfurization, this is one of the difficulties of natural gas transmission. There is still residual hydrogen sulfide in the natural gas treated by desulfurization and other processes. Therefore, the valves must be pipeline valves made of sulfur resistant materials.

Electromagnetic flowmeter has incomparable advantages in measuring the liquid flow of conductive medium. This year, electromagnetic flowmeter has been widely used in various industries, and more and more instrument workers who are required to maintain have more knowledge about electromagnetic flowmeter.
