Comate Intelligent Sensor Thermal mass flow meter datesheet TGF450 Series Thermal Mass Flowmeter 1. Brief Introduction 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 According to King’s law, the heating power P, the temperature difference ΔT (TRH-TRMG) and the mass flow rate are mathematical related . P/△T=K1+K2 f(Q)K3 , the K1、K2、K3 are constants related to the properties of the gas. TGF Series Thermal mass flow meter is designed base on constant power measuring method, thus the RTD is heated in a consistent power and will be more durable and stable. That is why TGF flow meter has less problem of zero-off which may caused by a function failure of RTD due to over-heated in long term. Email: info@comateflowm

Comate Intelligent Sensor Thermal mass flow meter datesheet 4. Process connection The TGF450 Series Thermal Flow meter has two different installation types, one is insertion and the other is in-line type. The insertion type can be installed and maintained on line. To install it, you have to weld and install a socket with screw thread outside on the pipe and install a 1 inch or 1/2 inch ball valve on the base. Then drill a hole of 13mm (or 22mm) diameter on the pipe with a special tool and install the flow meter on the pipe through the hole. The position and depth of how the sensor is fixed...

Comate Intelligent Sensor Thermal mass flow meter datesheet 2) Ball valve mounting When users want to replace or re-calibration or for any reason want to remove the flow meter while do not want to stop the flow , our ball valve mounting can help. Once the meter is installed with a customized ball valve, user can remove the meter away while still keep the pipeline sealed with the ball valve. This design should only be used when it is absolute necessary and the fluid is not explosive or hazard. Ball valve mounting 3) Hot taping driller Some user may not want to stop the flow when installing...
