I just recently put in a ground source heat pump, and I want a way to check the inlet and outlet temperatures of the water flow. I have a set of valves on a mettalic "Tee" in each line, which gives me a metal place to measure the flow temps. There is enough of a difference to readily notice by hand. Temps would be in the 45deg - 75deg F range.
What I would like is a way to measure by thermocouple using a cheap HF $4 digital VOM as a readout, I remember reading about this some years ago. I have a commercial Chromel/Alumel thermocouple (type K) which could work I think.
Can anyone point me to a simple circuit that would do what I am looking for?
TIA,
Steve
