Scope
This document specifies the metrological characteristics, calibration conditions, calibration items, calibration methods, expression of calibration results, and recalibration time intervals for on-site calibration of pressure-type sulfur hexafluoride (SF6) gas density controllers, also known as gas density relays (hereinafter referred to as density controllers). This document is applicable to on-site calibration of density controllers that use spring tubes or bellows as measurement elements, are equipped with temperature compensation devices, and have contact output functions.
