Fleisch type pneumotachometer
Flow (V') is being measured in a tube with a small, fixed resistance. In this type of
pneumotachograph the resistance to flow comes from an array of capillaries arranged in parallel with
the direction of flow (ref. 1). The pressure drop across the resistance relates linearly to flow at
relatively low flows, when the flow pattern is laminar. Higher flows give rise to a turbulent flow
pattern, when the pressure drop across the resistance changes more than proportionally with flow.
Accurate measurements are best performed when the flow pattern is laminar and flow linearly related
to pressure drop.
