Thermal Mass Flowmeter TMF


Size (mm)

Thermal gas mass flow meter is divided into Pipe-line and Insertion, according to installation infrastructure. It can be used for measuring gas such as Air, Oxygen, Methane, Natural gas and other mixture gas, except acetylene and humid gas.

Working principle

Thermal gas mass flow meter is designed based on thermal diffusion and adopt principle of constant temperature difference to measure gas.


Application industry
