... The Flow sensor element consists of two temperature depending platinum-resistors, both deposited on one chip. The low-ohm resistor with a small area is used as a heater, whereas the other high-ohm resistor serves to measure the reference temperature. Using a bridge circuit, the differing resistance value of two elements leads to different (self) heating ...

... Electronic circuit recommendation As shown on the scheme to the right, the heater R sensor R need to be connected in a bridge circuit essential to determine the correct values of the resistors R1, R2, and R3. The bridge is in balance as soon as the desired temperature difference between R and R S 30K changing flow the bridge voltage U_Bs needs to be controlled in dependence of the bridge balance V1-V2. The values for R1… ...
