I am trying to develop a btu calculator for my solar thermal water heater. I would eventually like to use labview to do the acquisition. I have an internal heat exchanger and know the temperature before and after it enters the exchanger. I have a flow meter w/ a pulse output. What would the equation look like to do the calculation? Can I use the volume of the exchanger (approx 2 gallons) multiplied by the gallon to pound conversion, then multiplied by the flow rate over the period of the exchange?(adsbygoogle = window.adsbygoogle || []).push({});

Thanks

Chris
