One of the most difficult problems facing the instrument engineer is the accurate calibration of orifice meters, particularly at remote or inaccessible locations. The object of this paper is to describe a unique solution to this problem, an automatic pneumatic deadweight test utilizing the floating ball principle. The Ametek Model PK Pneumatic Deadweight Tester is an ideal instrument to use for the calibration of orifice meters. This instrument provides unexcelled accuracy combined with reliable operation and ease of use for both field and laboratory calibration. It has been accepted by most of the gas transmission companies as a pressure standard for meter calibration.
