Description

Technical Field

[0001] The present invention relates to the field of metrology and detection, and particularly to a wet gas metering and detection device. Background Art

[0002] Wet gas flowmeters are divided into two types: one is made of brass and is generally used within the range of non-corrosive gases; the other is made of corrosion-resistant stainless steel and can measure corrosive gases. The LMF / LML series wet gas flowmeters are one of the commonly used instruments in laboratories. When measuring the total volume of gas, they have high accuracy, especially at low flow rates, with small errors. They can be directly used to measure gas flow and can also be used as standard instruments to calibrate other flowmeters.
