A portable universal unit for calibration and testing of liquid and gas meters and flowmeters

摘要

Information about the unit intended for calibration and testing of roller-paddle flowmeters (RPF) and quantity counters is presented. Working medium generators realized in the form of existing RPF types are utilized in the unit. The procedure offlowmeter metrological certification on the unit by comparison method is proposed. The procedure allows calibrating the dimension-type family of high-precision universal wide-range flowmeters and quantity counters of the 3{sup}(rd) roller-paddlegeneration under various flow modes.
