    Abstract: A digital fluid flow meter for measuring fluid flow past a surface on one side of a wall including first and second reduced thickness areas in the wall spaced from one another, a first detector having a first temperature sensitive element thermally coupled to the first reduced thickness area to provide thermal transfer between fluid in contact with the surface and the first detector, a second detector comprising a second temperature sensitive clement thermally coupled to the second reduced thickness area of said wall to provide thermal transfer between fluid in contact with the surface and the second detector. The digital fluid flow meter includes means for sensing the temperature of the first and second temperature sensitive elements, first and second heating elements for heating the respective temperature sensitive elements proximate to the first and second detectors, respectively.
