A new method for the calibration of peak flow meters
A new method for the calibration of peak flow meters
The objective of this paper is to assess the current methods for the calibration of peak flow meters and devise a method of producing a known flow with an inexpensive apparatus simple enough to be built from a set of dimensions. The methods currently available tend to be expensive and complex or impractical for routine use. The aim was that the wave form produced should approximate to a forced expiratory flow and be capable of being described in mathematical terms and be relatively inexpensive to produce. The resulting apparatus which has been built, produces a sine wave flow the peak of which can be set to any desired level and be determined to a high degree of accuracy. The apparatus can be built from a set of dimensions and is inexpensive. The apparatus is a primary and not a derived standard.

Abstract
The objective of this paper is to assess the current methods for the calibration of peak flow meters and devise a method of producing a known flow with an inexpensive apparatus simple enough to be built from a set of dimensions. The methods currently available tend to be expensive and complex or impractical for routine use. The aim was that the wave form produced should approximate to a forced expiratory flow and be capable of being described in mathematical terms and be relatively inexpensive to produce. The resulting apparatus which has been built, produces a sine wave flow the peak of which can be set to any desired level and be determined to a high degree of accuracy. The apparatus can be built from a set of dimensions and is inexpensive. The apparatus is a primary and not a derived standard.
