TGF450 Series Thermal Mass Flowmeter

Brand: Comate Flow Meter

TGF450 Series Thermal Mass Flowmeter is COMATE’s latest technology specially designed for air and N2 applications. It has more compact design, which means smaller enclosure and thinner insertion tube probe. 

Due to its small diameter insertion probe and shorter high-sensitive sensor, it can be used on pipes from DN25-DN500. 

In some higher pressure applications, it can be installed / removed without stopping the fluid, as the pipe is thinner, field engineers will be able to insert the meter to pipe very easily. 

Also, to fulfill the cost-saving demand in compressed air and N2 applications, TGF450 will be the most cost-effect model in the market.

TGF450 Series Thermal Mass Flowmeter measures the gas mass flow base on thermal diffusion theory. It has two RTDs as its sensors, one of which sense the velocity of the gas flow (RH) and the other one will detect the temperature shift of the gas flow (RMG). 

When the two RTD are in the gas flow, the RH will be heated while the RMG will sense the temperature changing of the gas flow. More heat will be taken away as the velocity of the gas flow increasing ,so the temperature on RH will decline.
