Head type devices measure flow by constricting a stream and measuring the resulting pressure drop. The pressure drop can then be related to a flow. ... The most common displacement flow-measuring device is the turbine meter. In a turbine meter, a rotor is placed in the flow path. Usually, the rotor is...

The thermistor was strongly nonlinear and flow reductions (hypopnoeas) were underestimated: a 50% reduction in V' (+/-0.5 L.s(-1), 15 bpm, sinusoidal) resulted in only an 18% reduction in V'th. V'th depended considerably on the airflow pattern: for V'=+/-0.5 L.s(-1), V'th increased by 100% from sinusoidal (20 bpm) to...
