Answer to Question 1

ANS: C
All pneumotachographs, except the ultrasonic pneumotachograph, operate on the principle that gas flow through them is proportional to the pressure drop that occurs as the gas flows across a known resistance.

Answer to Question 2

ANS: C
The vortex ultrasonic flowmeter uses struts to create a partial obstruction to gas flow. As gases flow past these struts, whirlpools (or vortices) are produced. The frequency at which these whirlpools are produced is related to gas flow through the struts.
