Methods of Reduction of Fuel Consumption Measurement Error by Thermo-Anemometric Flow Meter

It was analyzed the ways of influence on the indexes of radial heat flow in thermo-anemometric flow meter that will influence the indexes of axial heat flow, will make them more informative and this, in its turn, will affect the consumption measurement error. It was formulated the condition of selecting the temperatures distribution with the minimal measurement error for multi-sectional flow meter, it can be obtained by the indexes of thermal transformers of the very pipe of multi-sectional thermo-anemometric flow meter, where the maximal total temperatures difference between all the neighboring thermal transformers was measured. Expanding the range of fuel consumption measurement by the thermo-anemometric flow meter was suggested due to the application of sequentially axially installed sections with different diameters.
