Abstract
The invention refers to a method and device for air calibration of gas flowmeters designed for flowmeter calibration at high flow rate and gas yield.The method, in accordance with the invention, consists of sucking a gas with given and stabilized characteristics from an enclosure into a duct with constant inner diameter, and measuring the static and total pressure at the duct inlet where the speed is evenly distributed and the gas has an isentropic evolution.The device, in accordance with the invention, consists of an inlet section (1) connected to an intermediary section (2) on which the flowmeter to be calibrated (3) is mounted. Both sections have the same inside diameter. The inlet section (1) has at one end (a) a rounded border (b) and a static pressure probe (6) that is located in the same section as the total pressure probe of a Pitot tube (7). The intermediary section (2) is also connected to an exhauster blower (4), the flow being controlled through a valve (9).<IMAGE>
