Abstract
A peak flow measurement device comprises a hollow body (1) having an inlet (8) for receiving fluid and an outlet (3), wherein the inlet (8) and outlet (3) are spaced apart from each other, the cross-sectional area of the body being greater than the cross-sectional area of the outlet and wherein in use the device is oriented such that the inlet is above the outlet and the measured peak flow is proportional to the maximum height (11) of fluid within the body.
