Hot wire measurements the hot wire anemometer consists of a sensor, a small electrically the hot film sensor is essentially a conducting film laid on a ceramic or. Mass flow sensor wikipedia. The gm ls engine series (as well as others) use a coldwire maf system (produced by ac delco) that works similarly to the hotwire maf system; however, it uses an additional "cold" resistor to measure the ambient air and provide a reference for the "hot" resistor element used to measure the air flow.. The mesh on the maf is used to smooth out airflow to ensure the sensors have the best chance. Diy solar air heating collectors pop can vs screen absorbers. Diy solar air heating collectors are one of the better solar projects. They are easy to build, cheap to build, and offer a very quick payback on the cost of the materials to build them.
