About half of my house is heated with an oil furnace/base-board serial water system. This will be only my second winter in the house.
Due to the nature of the installation , there is no way to meaure the amount of fuel remaining in the fuel tank. (If there was ever a mamometer, its no longer visible.) I know the capacity of the tank only because I ran it dry at the beginning of last winter.
Therefore, I'd like to install a fuel-flow sensor in the 1/4" fuel line enters the boiler.
Minimally, a simple running total would suffice, but resetable counter showing gallons used since last refill would be nice.
Ideally, this meter would enable me to harvest usage data (via USB port) based upon date and time. Using this data, and correlating it with OAT from NOAA, I could construct a usage profile that would enable me to manage my fuel purchases rationally. (For example, the first cold snap is on its way and I have no idea how much fuel is in the tank, so I'm buying fuel today--probably than I need--at time when prices are rapidly falling.)
Does such a gadget exist? If so, I would appreciate links or other info to help research.
