It has the characteristics of high precision, wide measuring range, small size, light weight, easy installation and maintenance, reliable use and long service life. There are many kinds of instruments used to calibrate gas flow. Commonly used ones are gas rotary flowmeter and wet gas flowmeter. Now most gas calibration is used in laboratories and research institutions. Basically, wet gas flowmeter is used in laboratories. When calibrating gas, the gas is usually introduced into the calibration tube, and then tested and calibrated. Since the introduced gas will carry some air in, the air contains various trace amounts of carbon monoxide and carbon dioxide. These gases will interfere with the flow calibration detection, resulting in inaccurate gas calibration and affecting the experimental data.
