Scope

Main technical specifications: (1) Maximum allowable error of average flow rate: ≤±5%. (2) 24-hour zero drift: ≤±1% full scale (F.S.); weekly zero drift: ≤±2% F.S. (3) 24-hour range drift: ≤±1% F.S.; weekly range drift: ≤±2% F.S. (4) System response time: ≤5 s. (5) Zero flow reading: ≤0.01 m/s. (6) The insulation resistance between the power terminals and the grounding terminals, and between the output terminals and the grounding terminals of the flow meter is greater than 20 MΩ. (7) The power terminals and the grounding terminals, and the output terminals and the grounding terminals of the flow meter can withstand a frequency of 50 Hz, an AC RMS voltage of 1500 V, and a duration of 1 minute without arcing or breakdown. The technical specifications are verified through testing methods to ensure that the products leaving the factory meet the requirements of the technical specifications.
