Nancy Holmes (editorial director), Illustrated Manual of Nursing Practice, Wolters Kluwer Health (Lippincott Williams & Wilkins), 3rd Edition, page 154, While all spirometers encourage slow, sustained maximal inspiration, they can be divided into two types: flow incentive and volume incentive.

   Wet-type spirometers (such as the classical bell spirometer with a water seal) are simple and accurate but are no longer in use as they have a hygiene problem; they are distinguished from dry-type spirometers (e.g., bellows or piston spirometer).
