This standard specifies the terms and definitions, types and basic parameters, technical requirements, test methods, inspection rules, marking, packaging and storage of capacitive level meters (hereinafter referred to as meters). This standard is applicable to capacitive level meters that are composed of sensors and electronic conversion components and continuously measure liquid or material levels by detecting the capacitance between the two poles of the material in an open container or pressure vessel, as well as products derived and developed based on this principle. Radio frequency admittance level meter.
