Measuring air flow in an HVAC duct can be a tricky business ... The principle behind the sensor [ItMightBeWorse] is working on is nothing new. He discovered a paper from 2015 that describes ...
Because a precise mixture is crucial to efficiency and clean combustion, the MAF sensor accounts for differences in air density, which varies with temperature and altitude. A failed MAF sensor is ...
