Information on Flow Meter Manufacturers Web Listings Publications News Topics Information A spirometer is an apparatus for measuring the volume of air inspired and expired by the lungs. It is a precision differential pressuretransducer for the measurements of respiration flow rates. The spirometer records the amount of air and the rate of air that is breathed in and out over a specified time. The Spirometer and attached flow head function together as a pneumotachometer, with an output signal proportional to airflow. It was invented by John Hutchinson in 1846. [CaRP] Can't open cache file.
