Scope
This standard specifies the terms, metrological characteristics, calibration conditions, calibration items and methods, sealing and marking, processing of calibration results, and recalibration intervals for sewage treatment terminal discharge metering systems primarily composed of velocity-type flow meters or open-channel weir flow meters. The method specified in this standard is applicable to sewage treatment terminal discharge metering systems primarily composed of velocity-type flow meters or open-channel weir flow meters with a nominal diameter of DN ≤ 3000 mm, a flow velocity of (0.10~6.00) m/s, and a flow range of (5~150,000) m3/h.
