Hello.
I want to measure the temperature of flowing liquid at the beginning of the tube and compare the temperature at the end of the tube. The liquid heats as it goes through the tubing. The difficult part is that the tubing inner diameter is only 125 micrometers, and I want to be able to measure the temperature difference with 0.001 degrees C precision if possible.
Sorry, I am very new to this. If you could get me started with how this can be done, I'll research more into. I just couldn't find a good starting point, and my researching left me more confused.
One idea that I came across was to use a feedback circuit with thermopiles to measure the temperatures, which is used in calorimeters that use a reference cell and a sample cell. The feedback circuit is used to heat the cooler end and I can measure the differential power signal. However, this does not seem to be the best way, since I don't want to heat the other cooler end.
