Scope

This standard specifies the terms and definitions, product classification, basic parameters, technical requirements, test methods, inspection rules, marking, packaging, transportation and storage of jet water flow sensors. This standard applies to closed full-pipe jet oscillating water flow sensors (hereinafter referred to as sensors) powered by low-voltage DC (or battery) and pulse signal output. It also applies to jet cold and hot water meters, jet flow meters, and jet flow transmitters. Sensors in water flow detection instruments with a nominal diameter less than or equal to DN40, a maximum allowable working pressure (MAP) greater than or equal to 1.0 MPa, and a maximum allowable working temperature (MAT) less than 100°C.
