Thermal Mass Type Air Velocity and Flow Transmitter-FTM06T-A

FTM06T-A thermal mass type air velocity and Flow transmitter, contains three 

sensing elements (Rh / Rt / PT), the heater (Rh) is used for measurement, 

temperature compensation sensor (Rt), the temperature sensor (PT) that detects

 the air flow is used as a reference to measure the temperature of the medium.

Rh is the heating body, Rt is used to sense the temperature change of the water

 flow;as the water velocity increases, when the fluidpasses through Rh, it will take

 away more heat; PT will sense the current temperature of the gas at any time.

The temperature difference between the two sensors of Rh and PT is used as the

 basis for measuring the flow rate, when the medium flow rate increases, the 

temperature difference value is decreased, and conversely increase, the 

temperature difference value is processed and converted into standard signal 

output and displayed, through the unique linear regression technology, a good

 flow rate performance is obtained
