Pitot Flow Sensor, 1904, End-view
From: Die Geschwindigkeith des Athemstromes und das Athemvolum des Menschen, by H. Zwaardemaker and C.D. Ouwehand, Archiv für Anatomie und Physiologie, Volume 28, Published by Physiologische Gesellschaft zu Berlin, 1904, page 243.
An early flow measuring device. When a subject blew through the central tube (a), positive and negative pressure in the opposed pitot tubes (b) caused thin plastic domes (f) to rise or fall. Their movement was transferred to a long, counter-balanced pen which traced a curve on a smoked drum.

Spirometer, LSE Vanguard DS-601, circa 1980
Used a disposable pneumotach (plastic body with filter paper mesh). Manufactured by the LSE corporation in the 1980’s. There was an optional strip chart recorder for volume-time curves. Numerical results were displayed one at a time on the digital front panel by pressing a button to step through them. Taken from: http://www.ebay.com/itm/like/271258328169?lpid=82
Pneumotacograph, Fleisch, 1942
From: The Pleuro-subpleural Zone: Its Clinical & Experimental Investigation and Its Practical Importance in Chest Pathology by Josef Skládal, 1942, page 27. Fleisch’s original design used a mirror and a light beam to record air flow on photographic film.
