working principle:
R-FT Series thermal flow meter is designed based on the principle of thermal diffusion flow meter. When that is the use of fluid flow through the hot objects, hot objects of heat loss and how much fluid flow showed a certain proportion.
The series flowmeter sensor has two standard level of RTD, one used for heat, one for measuring the temperature of the fluid, when the fluid flow, the size of the temperature difference between the flow rate of a linear relationship.
Then through the micro-electronic control technology to convert this relationship to measure the flow linear output signal.
